Overview
The audio editor lets you trim, fade, and adjust the level, pitch, and speed of an audio file without leaving Projects or opening a separate app. You can edit any browser-playable file already in your project, or edit a take right after recording it.
The Edit audio option is only available to project Owners, Admins, and Editors. Viewers don’t see this option.
Step-by-Step Guide
Open the editor in one of two ways:
- From an existing file: click the more actions (...) menu on a project audio file and select Edit audio.
- From a fresh recording: in the Recorder’s preview step, select Edit.
Drag the trim handles on the waveform to set the start and end of your edit.
Under Processing, adjust your edit:
- Fade in / Fade out: up to 10 seconds, or the length of your trim selection, whichever is shorter
- Gain: from −24 dB to +24 dB
- Normalise: toggle on to bring your take to a consistent peak level
- Reverse: play the selection backwards
- Pitch / Speed: on supported browsers, adjust and bake these into your exported file (see limitations below)
Important noteIf your gain setting would clip the audio, red lines appear on the waveform where levels exceed the limit.
Choose your output format: WAV for full, uncompressed quality, or MP3 for a smaller file size.
Click Preview to listen to your edit before saving.
Save your edit:
- From an existing file, choose Upload as new version (keeps your edit as part of the same file’s version history) or Upload as new file (saves it as a separate file in the current folder/project).
- From a fresh recording, choose Apply edit to bring the edited take back into the Recorder.
Frequently Asked Questions (FAQs)
What order are my edits applied in?
Trim is applied first, then reverse, then normalise, then gain, then fades, then pitch and speed. This is worth knowing if you’re trying to predict how your final result will sound.
Why is “Upload as new version” greyed out?
This happens when your chosen output format doesn’t match the file’s original format. For example, if you’re editing a WAV file and select MP3 as the output, you’ll need to use Upload as new file instead, since a version needs to keep the same format as the original.
Does converting MP3 to WAV improve the quality?
No. WAV is a lossless container for your edited result, but converting an MP3 to WAV doesn’t recover any quality lost in the original MP3 compression.
Can I edit AIFF or ALAC files?
Only if your browser can play them. Safari can play AIFF and ALAC files directly, so editing might be available there. Chrome and Firefox can’t play these formats, so the Edit audio option won’t appear on them in those browsers.
Why don’t I see pitch and speed controls?
Pitch and speed adjustments aren’t available in Safari or in any browser on iOS, including Chrome on iPhone. These controls are hidden rather than offered with an unreliable result. If you need to adjust pitch or speed, use Chrome, Edge, or Firefox on desktop or Android.
Why can’t I change the output format when editing a fresh recording?
If your recording included an audio track, the output format is locked to match that track’s format to keep the two compatible if you upload your edited take as a new version.
Do the fade curves I see match what gets exported?
The curved fade shape you see on the waveform is a visual preview. Exported audio currently uses a straight (linear) fade.
If I edit a recording that had timing issues with the backing track, does the editor fix that?
No, the editor doesn’t handle timing alignment. If you edit a take that was recorded with a backing track and had sync calibration applied in the Recorder, that same calibration carries over automatically when your edit is applied back to the take. You don’t need to redo anything in the editor.
