01Introduction
Audiopod is a full-featured podcast editor that runs entirely inside your web browser. No additional software to install, no account to create, and no files uploaded to any external server.
What is Audiopod
Audiopod is a podcast editor designed to be used directly in the browser, with no desktop application or browser extension required. All audio processing — recording, editing, effects, mixing, and export — takes place locally on your device, inside the browser's JavaScript engine, using the Web Audio APIs.
You can record your voice straight from the microphone, import existing audio files, edit them on a multi-track timeline, apply professional audio enhancements, and export the final result as a WAV or MP3 file ready to publish. Your audio never leaves the device.
The app is ideal for podcast creators who want a fast, private workflow without depending on cloud service subscriptions or paid software. The interface is available in Catalan and English, and adapts to large screens and tablets alike.
Key advantages
- Total privacy: your audio never leaves your device. No files are sent to any external server. Data is stored locally in the browser's IndexedDB.
- Cross-platform: works on any operating system with a modern browser: macOS, Windows, Linux, ChromeOS, and even iPadOS (with limitations).
- Auto-save: all changes are saved automatically as you work. No need to press a save button manually — you won't lose anything if you accidentally close the tab.
- Non-destructive editing: editing tools preserve the original data until the final export. You can undo any operation at any time with ⌘Z.
- No installation: open the browser, go to the URL, and start working. App updates arrive automatically with nothing to do on your end.
- Professional-grade tools: includes a compressor, EQ, noise gate, DeEsser, noise reduction, and LUFS normalization — the same tools found in paid desktop DAWs.
Recommended browsers
Audiopod works best in Chromium-based browsers. Here is a summary of compatibility:
| Browser | Compatibility | Notes |
|---|---|---|
| Google Chrome | Recommended | Best performance and full compatibility. Version 90 or later. |
| Microsoft Edge | Recommended | Chromium-based, equivalent performance to Chrome. |
| Mozilla Firefox | Compatible | Works correctly. Version 95 or later recommended. |
| Safari | Caution | Works, but Safari may delete IndexedDB data if the site is not visited for more than 7 days. Make ZIP backups regularly. |
| Brave / Opera | Compatible | Chromium-based. Make sure they are not blocking the Web Audio APIs. |
Safari enforces a data-deletion policy for rarely visited websites. If you do not use Audiopod for 7 days or more, Safari may erase projects stored in IndexedDB. To avoid losing your work, always export a ZIP copy of important projects once they are finished.
First steps
Getting started with Audiopod is quick. Follow these steps to create your first project:
- Open the browser and go to the Audiopod URL. You will see the main project management screen.
- Click "New from file" if you already have an audio file (interview, voiceover, music, etc.), or click "New recording" to record directly from the microphone.
- If you are importing a file, select it from your operating system's file manager. The app accepts WAV, MP3, OGG, M4A, FLAC, and WebM.
- Once the project is created, the timeline editor will open. The audio file will appear as a clip on the first track.
- Press Space or the play button to listen to the content. Use the editor tools to trim, split, and enhance the audio.
- When you are satisfied, click the "Export" button to generate the final file and download it.
02Project management
The main Audiopod screen is the project manager. Here you can create, open, rename, delete, and back up your podcast projects.
Creating a project from a file
If you already have a previously recorded audio file — for example, an interview recorded on your phone, a voiceover captured with another app, or a music track — you can create a project from it directly.
Click the "New from file" button on the project management screen. Your operating system's file manager will open. Select the audio file you want to import. Audiopod accepts the following formats:
| Format | Extension | Notes |
|---|---|---|
| WAV | .wav | Maximum quality, no compression. Recommended for original masters. |
| MP3 | .mp3 | Very common compressed format. Compatible with all sources. |
| OGG Vorbis | .ogg | Open compressed format. Good quality at small file sizes. |
| M4A / AAC | .m4a | Apple format, very common on iOS and macOS devices. |
| FLAC | .flac | Lossless compression. Maximum quality with smaller files than WAV. |
| WebM | .webm | Web video/audio format. Supported when it contains an Opus or Vorbis audio track. |
Once the file is selected, the app will create a new project named after the file (without the extension) and open the editor with the imported content on the first track, ready to edit.
You can also drag an audio file from your operating system's file explorer directly onto the editor timeline to add it as a new track. No need to go back to the project screen.
Creating a project from a recording
If you want to record audio directly using your device's microphone, click the "New recording" button on the project management screen. The recording dialog will open.
The dialog lets you select the microphone device, adjust the input gain, and monitor the level in real time before and during recording. See the Audio recording section for full details on the recording workflow.
Once the recording is finished and you press the "Stop" button, the app will automatically create a new project and open the editor with the recording as the first track. The project name is generated automatically using the recording date and time; you can rename it at any time.
Opening, renaming, and deleting projects
Opening an existing project
All created projects appear in the list on the project management screen, sorted by last-modified date (most recent first). To open a project, click the "Open" button that appears to the right of the project name. The editor will load with the state in which you last left it.
Renaming a project
Once the project is open in the editor, the project name appears in the top bar (topbar). Click the name to edit it directly. Type the new name and press Enter to confirm, or Esc to cancel. The change is saved automatically.
Deleting a project
In the project list on the main screen, each project has a delete button (bin icon or "Delete" button). Clicking it will prompt you for confirmation before permanently deleting the project. This action cannot be undone, so make sure you have exported a ZIP copy if you need to keep the content.
Storage space
Audiopod projects are stored in IndexedDB, the browser's local database. Unlike cookies or localStorage, IndexedDB can store large files (tens of gigabytes) and persists across sessions, even when the browser is closed.
Available space depends on the device and browser, but in general a modern hard drive with free space allows for projects of considerable size. Audiopod monitors the percentage of the browser's storage quota in use and displays a visible warning when more than 80% of the available quota is used.
If you see the storage warning message, export old projects as ZIP files and delete them from Audiopod. Deleted projects free up space in IndexedDB. Exported ZIP files are saved to your local file system and can be re-imported at any time.
Recommendations for managing storage space:
- Export a ZIP copy of each project once the episode is finished and published.
- Delete old projects you no longer need to edit.
- If a session involved many takes, delete unnecessary draft tracks before saving.
- Avoid importing high-resolution WAV files (24-bit/96 kHz) unless strictly necessary; 16-bit/44.1 kHz already delivers maximum quality for podcasts.
03The editor — overview
The Audiopod timeline editor is the main workspace. This is where you assemble and edit the episode: arrange clips, trim segments, apply effects, and prepare the content for export.
Interface anatomy
The editor interface is divided into four main areas:
- Topbar (top bar): displays the project name (editable), global action buttons (export, add track, preferences, language, color mode), and status indicators.
- Transport bar: playback controls (play, stop, skip forward/back), time position indicator, zoom slider, and undo/redo buttons.
- Multi-track timeline: the central area of the editor. On the left are the track headers (name, volume, mute, solo); on the right, the content of each track with audio clips represented as waveforms. The time ruler appears at the top of the timeline.
- Toolbar: contextual editing tools (split, delete clip, delete range, ripple delete, silence range, fade in, fade out) and audio enhancement tools.
Transport bar
The transport bar gives you full control over project playback. Here is a description of each control:
- Play / Pause (Space): starts or pauses playback from the current cursor position. If the cursor is at the end, playback resumes from the beginning.
- Stop: stops playback and returns the cursor to the previous playback point (or the beginning if there was none).
- Skip −5s: moves the playback cursor 5 seconds back. Useful for re-listening to a segment without manually repositioning the cursor.
- Skip +5s: moves the playback cursor 5 seconds forward.
- Time indicator: shows the current cursor position in
MM:SS.ssformat. In some modes it also shows the total project duration. - Zoom slider: controls the timeline zoom level. Drag right to zoom in (see detail) and left to zoom out (see the whole episode).
Zoom and navigation
To navigate efficiently through a long episode, Audiopod offers several options:
- Zoom slider: in the transport bar. Adjust the zoom to view a segment in detail or the full episode at once.
- Horizontal scroll: when the zoom makes the content wider than the screen, a horizontal scrollbar appears at the bottom of the timeline. Use it to move through the timeline.
- Minimap: a thumbnail view at the bottom of the timeline showing the position and size of the current view relative to the total content. Click the minimap to quickly jump to any part of the episode.
- Click on the time ruler: click on the ruler (the numbered bar at the top of the timeline) to move the playback cursor to the desired point.
Selecting elements
Most editing operations require something to be selected. Here is how to select the different elements:
Selecting a clip
Click on any clip (waveform) in the timeline. The selected clip is highlighted with an amber outline. Once a clip is selected, you can apply operations such as Split, Delete, Fade In or Fade Out, or audio enhancement tools.
Selecting a range (time zone)
Click on an empty space on a track (where there is no clip) and drag horizontally. A semi-transparent blue highlighted range selection will be created. With a range selected you can apply: delete range, ripple delete, or silence range.
Selecting an entire track
Click on the track header (the area on the left with the name, sliders, and mute/solo buttons). The selected track is highlighted. With a track selected, the audio enhancement tools act on all clips in the track.
Deselecting
Press Esc to clear any active selection. You can also click on an empty space outside any track.
Undo and Redo
Audiopod maintains a complete history of all editing operations performed during the session. You can undo and redo operations at any time:
- Undo: ⌘Z (macOS) or Ctrl Z (Windows/Linux), or the "Undo" button in the toolbar.
- Redo: ⌘⇧Z (macOS) or Ctrl ⇧Z (Windows/Linux), or the "Redo" button in the toolbar.
The operation history includes all timeline edits (splits, deletions, position changes), audio processing operations (auto-enhance, EQ, compressor, etc.), track volume changes, and adding or removing tracks. The history resets when you close and reopen the project.
04Tracks
Tracks are the vertical channels of the timeline. Each track contains one or more audio clips that play back in parallel. You can have as many tracks as you need to organise voice, music, and sound effects.
Adding a track
There are several ways to add a track to the project:
- "+ Track" button: the topbar has a "+ Track" button. Clicking it adds an empty track at the end of the timeline. You can drag clips onto this track or import audio directly into it.
- Drag an audio file: drag any audio file from your operating system's file explorer and drop it directly onto the timeline. The app will automatically create a new track with the clip at the timeline point where you dropped it. If you drop it onto an existing track, the clip will be added to that track.
- Add via recording: when you record audio using the "New recording" button, the recording is automatically added as a new track.
Track header
On the left side of the timeline, each track has a header containing its main controls. Here is what each element does:
Track name
By default, tracks are named "Track 1", "Track 2", and so on. You can change the name by clicking on the name text in the header. The field becomes editable; type the new name and press Enter to confirm. Using descriptive names (such as "Host voice", "Background music", "Effects", "Guest voice") will help you stay oriented in complex projects with many tracks.
Volume slider (gain)
Each track has a volume slider that controls the playback gain — how loud that track plays relative to the others. The default value is centred (neutral gain, 0 dB). Move the slider right to raise the track volume, left to lower it. This is useful for balancing the relationship between the voice (should always be the loudest) and background music (typically −15 to −20 dB below the voice).
M button (Mute)
The M button mutes the track during playback. A muted track is neither heard nor included in the export. The button is highlighted (typically in yellow or orange) to indicate that the track is muted. Click again to unmute it. Mute is useful for comparing how the project sounds with and without a track, or for temporarily disabling tracks you do not need at a given moment.
S button (Solo)
The S button activates solo mode for that track: it mutes all other tracks and plays only the soloed track. This is especially useful for listening to a track in isolation and checking whether the audio processing sounds right. You can solo multiple tracks simultaneously, so only the tracks with solo active will be heard. Click the S button on the track again to deactivate solo.
× button (Delete track)
The × button deletes the track and all the clips it contains. The app will ask for confirmation. This action can be undone with ⌘Z.
Working with multiple tracks
Audiopod supports an unlimited number of tracks. The timeline scales vertically to accommodate as many tracks as you need, and you can scroll vertically to see them all.
A typical track layout for an interview podcast might look like this:
- Track 1 — Host voice: the main voice asking questions or presenting content.
- Track 2 — Guest voice: the interviewee or guest voice. Recording it on a separate track allows you to apply different audio processing to it.
- Track 3 — Intro/outro music: the theme music or jingle for the start and end of the episode.
- Track 4 — Background music: low-volume ambient music used during specific sections of the episode.
- Track 5 — Sound effects: punctual sounds (transitions, applause, etc.).
Remember to use the volume sliders to balance each track, and the Mute and Solo buttons to review each element separately during editing.
05Clips
A clip is the basic unit of audio in the editor. Every imported audio file, every recording made, and every segment resulting from a split operation is an independent clip that you can move, trim, process, and arrange on the timeline.
What is a clip
Visually, a clip is represented as a waveform inside a timeline track. The horizontal length of the clip corresponds to its duration. You can see the audio amplitude (volume) reflected in the height of the waveform: silent areas appear as a flat line in the centre, while loud audio shows larger waves.
Each clip is independent of the rest: you can apply audio processing to a specific clip (for example, normalise only one particular segment), move it to a different position on the timeline, or delete it without affecting adjacent clips. When you split a clip, the two resulting fragments become independent clips.
The clip name (if any) appears at the top of the clip on the timeline. Selected clips are shown with an amber-coloured outline to distinguish them.
Splitting a clip (Split)
The split operation cuts a clip into two fragments at the exact point where the playback cursor is located. This is one of the most commonly used editing operations, as it lets you:
- Remove a portion from the middle of a segment (mistakes, swear words, overly long pauses).
- Break a long clip into segments that you can reorder.
- Apply different processing to two parts of the same original audio file.
To split a clip:
- Click on the clip you want to split to select it (it will be highlighted in amber).
- Move the playback cursor to the exact point where you want to make the cut. You can use playback (press Space and press it again where you want to stop) or click on the time ruler.
- Press S or click the "Split" button in the toolbar. The clip will be divided into two independent clips at the cursor point.
Both resulting clips retain the original audio. You can now select one of the two clips and delete it, move it, or apply different processing to it.
Deleting clips and ranges
Deleting a clip
Select the clip by clicking on it and press Del or ⌫, or click the "Delete clip" button in the toolbar. The clip is removed and leaves a gap (silence) in its place on the timeline. Adjacent clips do not move.
Deleting a range (leaving the gap)
Drag across an area of the timeline to create a range selection (it will appear highlighted in blue). Click the "Delete range" button. All audio contained within the selected range is deleted, leaving a silence gap in its place. Clips to the right of the range do not move, so the timing of the rest of the project is preserved.
Delete and close the gap (Ripple delete)
Ripple delete is a particularly powerful operation for removing segments without leaving gaps. Select a range and click the "Delete and close" button (or press ⇧Del). The app deletes the selected range and shifts all clips to the right forward to close the gap, as if the deleted time had never existed.
Use ripple delete to remove:
- Long silences between sentences.
- Segments where the speaker gets lost and restarts a phrase.
- Sections of content you have decided not to include in the final episode.
- Swear words, sneezes, coughs, or other unwanted sounds.
Use Delete range when you want to keep the timing of the rest of the project (for example, to leave a deliberate pause). Use Ripple delete when you want the following content to shift forward to fill the removed space, maintaining the narrative continuity of the podcast.
Silencing a segment, Fade In, and Fade Out
Silencing a segment
Sometimes you do not want to remove a segment but simply make it silent (for example, a very loud breath that is noticeable if cut but goes unnoticed if reduced to silence). Select a range on the timeline and click the "Silence range" button. The selected zone is converted to silence, but the clip still occupies the same time slot. This operation can be undone with ⌘Z.
Fade In
A fade in is a smooth transition from silence to normal volume at the start of a clip. It avoids abrupt pops or cuts at the beginning. To apply one:
- Select the clip on which you want to apply the fade in.
- Click the "Fade In" button in the toolbar.
- Enter the fade duration in seconds. The valid range is 0.1 to 10 seconds. A fade in of 0.5 to 1 second is usually sufficient for voice; for music you may need fades of 3 to 5 seconds.
- Confirm. The clip waveform will show the volume ramp at the start.
Fade Out
A fade out is the reverse transition: the volume gradually decreases to silence at the end of the clip. Very useful for fading out background music or smoothly exiting a section. The process is the same as Fade In, but clicking the "Fade Out" button. The recommended duration for podcasts is 0.5 to 2 seconds for voice, and 3 to 8 seconds for music.
06Audio enhancement
Audiopod includes a complete set of audio processing tools to improve sound quality. You can apply the full enhancement chain with a single click, or use each tool individually for finer control.
To activate the audio enhancement tools, you must have a clip or track selected. If nothing is selected, the enhancement buttons will be disabled (greyed out). Click on a clip or on a track header to select them.
Auto-enhance
The Auto-enhance button (highlighted in amber in the toolbar) is the fastest way to achieve professional-quality audio with a single click. When pressed, the app automatically applies the full processing chain in the optimal recommended order:
- Noise reduction: continuous background noise is removed first, so subsequent tools do not process it unnecessarily.
- DeEsser: excessive sibilance is reduced, which can cause distortion in dynamics processors.
- Equaliser (EQ): the recommended voice filter is applied to add clarity and presence to speech.
- Compressor: volume variations are evened out to achieve a consistent, clean voice.
- Noise gate: the gate is applied to remove any residual noise that may remain during silences.
- LUFS normalisation to −16: the final volume is adjusted to the standard level for podcasts (−16 integrated LUFS), the value recommended by Spotify and Apple Podcasts.
Auto-enhance is recommended for the vast majority of cases. If the result is not perfectly to your liking, you can undo it with ⌘Z and apply the individual tools to fine-tune the parameters.
Individual tools
The individual tools are available in the "Audio enhancement" dropdown in the toolbar. Each tool acts on the selected clip or track:
Normalize
Adjusts the maximum amplitude peak of the clip to −1 dBFS. Ensures the audio uses the full available dynamic range without clipping. Useful as a first step if the audio is very quiet.
Equaliser (EQ)
Applies a filter optimised for spoken voice: a high-pass filter at 80 Hz to remove low-frequency noise (air conditioning, vibrations), +3 dB at 3 kHz for presence and intelligibility, and −2 dB at 400 Hz to reduce a "boxy" sound.
Compressor
Reduces the volume difference between the loudest and quietest parts of the voice. Parameters: ratio 3:1, threshold −18 dBFS. Result: a consistent voice that sounds professional even without perfect microphone gain staging.
Noise gate
Cuts the audio in segments that fall below the threshold (−40 dBFS by default) — that is, moments when the speaker is not speaking. Removes light background noise during silences, making the track sound clean between words and sentences.
DeEsser
Reduces excessive sibilance — the "s", "sh", and "z" sounds that on certain microphones or at certain distances can sound too aggressive or exaggerated. Ideal for condenser microphones that are very sensitive to high frequencies.
Noise reduction
Analyses and removes continuous background noise such as air conditioning, computer fans, or electrical hum. The tool performs a spectral analysis to identify the noise profile and subtracts it from the useful audio.
Trim silences
Automatically detects silences longer than 1.5 seconds and trims them down to 0.5 seconds. Saves editing time by removing excessively long pauses without having to locate them manually one by one.
Loudness LUFS
Normalises the perceived volume (integrated loudness) to the target level. Available options: −16 LUFS (Spotify and Apple Podcasts standard), −14 LUFS (YouTube), −19 LUFS (broadcast EBU R128). Always apply this step last in the processing chain.
If you apply the tools one by one, the recommended order is: Noise reduction → DeEsser → EQ → Compressor → Noise gate → Loudness LUFS. Applying them in a different order may produce less optimal results. For example, applying the compressor before the EQ can amplify the frequencies you intend to cut.
Remember that any processing operation can be undone with ⌘Z (macOS) or Ctrl Z (Windows/Linux). Don't be afraid to experiment with the individual tools to find which result best suits your microphone and recording environment.
07Audio recording
You can record your voice directly from the microphone without leaving Audiopod. The recording dialog gives you control over the device, gain, and signal level in real time.
Access and microphone selection
To access the recording dialog, click the "New recording" button on the project management screen. If you are already in the editor and want to add a recorded track, you can find the recording button in the toolbar.
The first time you try to record, the browser will display a permissions dialog asking for microphone access. Grant permission to continue. You can manage microphone permissions at any time from the browser's privacy settings.
Once the recording dialog is open, you will find a dropdown listing all available microphone devices on the system. If you have multiple microphones (for example, the laptop's built-in microphone and an external USB microphone), you can select which one to use. Always use a quality external microphone over the laptop's built-in one.
The browser may ask for microphone permission once and remember it, or ask again each session, depending on the settings. If you accidentally click "Block", you will need to go to the browser settings and manually unblock microphone access for the Audiopod domain.
VU meter and gain control
Before recording, it is crucial to adjust the input level so that the audio is neither too quiet nor too loud (saturated). The recording dialog shows two elements to help you:
Input gain slider
The "Input gain" slider has a range from 0× (mute) to 10× (maximum gain). The default is 1× (no modification). If the voice looks very quiet on the VU meter (the bar barely moves), increase the gain to 2–4×. If the voice is clipping (the bar reaches red), reduce the gain. Note: excessively high gain can introduce noise; it is better to speak a little closer to the microphone than to push the digital gain too high.
VU meter (level bar)
The level bar shows the microphone signal volume in real time, even before pressing "Record". Interpret the colours as follows:
| Colour | Indicates | Recommended action |
|---|---|---|
| Green | Correct level (approx. −18 to −6 dBFS) | Optimal. Start recording. |
| Orange (hot) | High level, close to the limit (approx. −6 to 0 dBFS) | Workable, but headroom is low. Consider reducing gain or moving slightly further from the microphone. |
| Red (clip) | Clipping — signal exceeds 0 dBFS | Reduce the gain or move away from the microphone immediately. Clipped audio cannot be repaired. |
Record, pause, and stop
Once the microphone is configured and the gain adjusted, follow these steps to record:
- Click the "Record" button (the red circle). Recording begins immediately. An elapsed time counter appears next to the button to show the duration of the current recording.
- Speak naturally into the microphone. Watch the VU meter: it should stay mostly in green, peaking into orange at louder moments. Avoid red.
- If you need to take a break (to check notes, have a drink of water, etc.), click the "Pause" button. Recording stops temporarily. The counter pauses. Click "Resume" to continue; the recorded audio is joined seamlessly without interruptions.
- When you are done, click the "Stop" button. The recorded audio is processed and automatically added as a new track to the project. If you were on the project screen, the editor will open with the new track.
Tips for a good recording
The quality of the recorded audio depends greatly on the environment and microphone technique. Here are the most important recommendations:
- Quiet environment: record in a room with little reverb and no background noise. Close the windows, turn off fans, appliances, and air conditioning. Small rooms with furniture and soft furnishings absorb sound better than large, empty rooms.
- Microphone distance: keep the microphone 15 to 30 cm from your mouth. Too far away and the sound will be quiet and reverberant; too close and it can cause distortion and exaggerated breathing noise.
- Avoid plosives: the letters "p", "b", and "t" can cause loud pops. Use a pop filter (windscreen) if you have one, or speak slightly to the side of the microphone rather than directly in front of it.
- Do a 10-second test: before recording the full episode, record 10 seconds of a test and listen back with headphones to verify the sound is clean and the level is correct.
- Once recorded, apply Auto-enhance: even a good recording benefits from the automatic processing chain. Select the recorded track and click the Auto-enhance button to polish the sound professionally in one click.
08Markers and chapters
Markers let you flag important points on the timeline (topic changes, guest entries, musical sections) and are automatically exported as ID3 chapters when generating the final MP3.
Adding and managing markers
Markers are visual indicators that appear as vertical lines on the timeline. You can add as many markers as your episode has sections or chapters.
To add a marker:
- Move the playback cursor to the point on the timeline where you want to place the marker. You can use playback (press play and pause where you want) or click directly on the time ruler.
- Press M or the marker button in the toolbar. A coloured vertical line will appear on the timeline and a dialog will ask you for the marker name.
- Type the chapter name (for example, "Introduction", "Interview with John Smith", "Conclusion", etc.) and confirm. If you leave the field blank, the marker will be added without a name.
Renaming a marker
To change the name of an existing marker, double-click on the marker line in the timeline. The name editing dialog will open. Enter the new name and confirm.
Deleting a marker
Click on the marker line in the timeline to select it and press Del or the delete button in the toolbar. Deletion can be undone with ⌘Z.
Navigation with markers
Markers act as navigation points. You can click on a marker in the timeline to jump directly to that point in the episode. Some external players (Apple Podcasts, Overcast) display the chapter list to help listeners navigate.
Exporting ID3 chapters
When you export the project in MP3 format, all markers are automatically included as ID3 chapters (CHAP / CTOC tags in the ID3v2.3 format). You do not need to do anything special; simply make sure you have added the markers and named each one, then click "Export".
ID3 chapters are compatible with:
- Apple Podcasts: displays the chapter list in the player and lets listeners skip between sections.
- Overcast: popular iPhone podcast player that prominently displays chapters.
- Pocket Casts: compatible with ID3 chapters.
- Spotify: displays chapters if uploaded through a compatible distributor.
- Most modern players that support ID3v2.3 or later.
Note: chapters are not included in WAV exports, as the WAV format does not support chapter metadata in the same way as MP3.
09Export
Once your podcast episode is ready, export it as an audio file to upload to your distribution platform. Audiopod generates the file entirely in the browser and delivers it directly as a download.
Export formats
To access the export options, click the "Export" button in the topbar. It is only visible when the project has audio. A dialog will open with format, quality, and metadata options.
Audiopod exports in two main formats:
WAV (lossless)
WAV is an uncompressed audio format. Every audio sample is stored in its original form, with no quality degradation. The resulting WAV files will be considerably large (approximately 10 MB per minute at 44.1 kHz / 16-bit stereo), but quality is at its maximum.
Recommended for:
- Keeping the original master of the episode for future use.
- Delivering audio to a producer, sound studio, or professional platform.
- Situations where quality is an absolute priority over file size.
MP3 (compressed)
MP3 is the standard format for podcasts. It uses lossy compression to significantly reduce the file size while maintaining perceptually acceptable quality for most listeners. Three quality options are available:
| Quality | Bitrate | Approx. size per hour | Recommended for |
|---|---|---|---|
| Standard | 128 kbps | ~57 MB | Simple voice content, low-budget podcasts. |
| Recommended | 192 kbps | ~86 MB | Standard podcast. Good quality/size balance. Recommended for most use cases. |
| Maximum | 320 kbps | ~144 MB | Podcasts featuring music or high-quality sound effects. |
ID3 metadata
ID3 metadata is information about the episode embedded inside the MP3 file. Podcast players and distribution platforms use this metadata to identify and display the episode correctly to listeners. Here is what each field does:
| Field | ID3 tag | Description |
|---|---|---|
| Title | TIT2 | Episode title. Will appear in all players. E.g.: "Ep. 42: The future of AI". |
| Artist | TPE1 | Name of the podcaster or hosts. Can be the show name. |
| Album | TALB | Name of the podcast (the show as a whole). E.g.: "Generation AI". |
| Episode number | TRCK | The episode number within the series. E.g.: "42" or "S2E05". |
| Genre | TCON | Content genre. For podcasts: "Podcast" or "Technology", "Education", etc. |
| Year | TYER | Publication year. E.g.: "2025". |
| Cover art | APIC | JPG or PNG cover image. Drag the image to the field or click to select it. Recommended: square, 3000×3000 px, under 500 KB. |
If you have added markers to the timeline (see the Markers and chapters section), they will be automatically included as ID3 chapters in the exported MP3. No additional configuration required.
Export process
- Click the "Export" button in the topbar. The export dialog will open.
- Select the format (WAV or MP3) and, if MP3, the desired quality.
- Fill in the ID3 metadata (especially the title and podcast name).
- Add the cover art if you have one.
- Click "Export" inside the dialog. The app will process all tracks, mix them, and apply compression if applicable. A progress indicator will show the advance.
- Once complete, the browser will automatically download the file to the system's downloads folder.
The duration of the export process depends on the project length and device specs. A 30-minute episode typically exports in under a minute on a modern computer.
10Backups (ZIP)
ZIP backups let you take your Audiopod projects anywhere, create external copies, and protect yourself against browser data loss.
Why make backups
Audiopod projects are stored in IndexedDB, the browser's local database. This storage is convenient and persistent, but it has important limitations you should be aware of:
- Device-bound: projects in IndexedDB are not automatically synced between devices. If you want to continue working on another computer, you need the ZIP file.
- Browser-bound: if you use Chrome at work and Firefox at home, each browser has its own IndexedDB. A project created in Chrome will not appear in Firefox unless you import it.
- Deletion risk: if someone clears the browser data (cache clearing, browser uninstallation), projects are deleted. Safari may delete them automatically if the site is not visited for 7 or more days.
- Portability: a ZIP file is a standard file you can copy to an external hard drive, upload to a cloud service (Google Drive, Dropbox, iCloud), or send by email.
Exporting a project as ZIP
On the project management screen, each project in the list has the "Export ZIP copy" button available. Clicking it will generate a .zip file containing:
- The JSON file with the project structure: tracks, clips, positions, fades, markers, metadata, and operation history.
- All original audio files imported or recorded in the project, in their original format.
The resulting ZIP file will be automatically downloaded to the system's downloads folder. The filename follows the format ProjectName_YYYY-MM-DD.zip. Keep it in a safe place.
Importing a project from a ZIP
To restore a project from a previously exported ZIP file, follow these steps:
- On the project management screen, click the "Import ZIP" button at the top of the project list.
- The system file manager will open. Browse to the project ZIP file and select it.
- The app will unzip the archive, read the JSON and audio files, and rebuild the project in IndexedDB. The project will appear in the list, ready to open.
The import is non-destructive: if a project with the same name already exists, the app will create the imported project with a slightly different name to avoid conflicts (for example, "My episode (2)").
Make it a habit to export a ZIP copy of each project once the episode is finished and published. Store the ZIPs in a folder organised by year or show in your local file system. Also consider keeping copies on a cloud service such as Google Drive or Dropbox for additional protection.
11Keyboard shortcuts
Keyboard shortcuts significantly speed up the editing workflow. Learning the most common shortcuts will let you work much faster and more fluidly.
You can display the shortcuts list at any time from the editor by pressing the ? key.
| Action | Shortcut (macOS) | Shortcut (Windows/Linux) |
|---|---|---|
| Play / Pause | Space | Space |
| Split clip at cursor | S | S |
| Add marker | M | M |
| Delete selected clip or range | Del / ⌫ | Del / Backspace |
| Delete range and close gap (Ripple delete) | ⇧ Del | Shift Del |
| Undo | ⌘ Z | Ctrl Z |
| Redo | ⌘ ⇧ Z | Ctrl Shift Z |
| Clear selection | Esc | Esc |
| Show shortcuts help | ? | ? |
All keyboard shortcuts are available when the editor has focus. If shortcuts are not responding, click once on the timeline to make sure the editor has keyboard focus (and not, for example, an open text field).
12Preferences
Audiopod adapts to your visual and language preferences. All preferences are automatically saved in the browser and remembered across sessions.
Dark mode and light mode
Audiopod offers a dark mode (black/dark grey background) and a light mode (white/light grey background). To switch between the two modes, click the sun/moon button (☀ / ☾) in the topbar, at the top right of the editor.
By default, the app automatically detects the operating system's preference. If your system uses dark mode, Audiopod opens in dark mode; if it uses light mode, it opens in light mode. Once you manually change the mode using the button, your choice is remembered and takes priority over the system preference.
To return to automatic system detection, you can reset the preference via the button (in some browsers, clearing the site data will restore automatic detection).
Language
Audiopod is available in two languages:
- Catalan — default language if the browser detects a Catalan regional setting.
- English — default language for all other regional settings.
To change the language, click the globe button (🌐) in the topbar. A menu will appear showing the available language options. Select the desired language; the interface reloads immediately in the new language. Your choice is saved and remembered in the next session.
Note: the language setting affects all interface text (labels, buttons, error messages, etc.), but does not affect project content (track names, clip names, metadata, etc.) or the documentation.
Other remembered behaviours
Audiopod automatically remembers your preferences between sessions for:
- Timeline zoom level.
- Timeline scroll position.
- Selected microphone device (if the browser keeps it available).
- The last opened project (suggested when the app opens).
