How to use
Free online audio editor: trim clips, merge several files, adjust gain, fade in and out, change speed or reverse, and extract the audio track straight from MP4 / MOV files - then export as WAV. Everything runs locally in your browser, nothing is uploaded, no signup.
- To grab audio from a video, just upload the MP4 / MOV - the audio track is extracted automatically.
- Output is WAV: 16 and 24 bit are lossless PCM, 32 bit is float - all ready for a further pass in an editor.
- Worried about size? Pick mono and drop the sample rate to 16000 Hz to cut the file to roughly a quarter.
- Merge mode joins files in list order and can insert silence between clips - handy for megamixes or podcast intros.
- Fades are in seconds; when both ends exceed the clip length they are scaled down so they never fight each other.
