Why WAV for editing
Every time audio is encoded to a lossy format like MP3 or AAC, a little detail is thrown away. If you extract to MP3, then edit, then export to MP3 again, the losses add up. WAV avoids one of those steps.
Most audio software opens WAV directly: Audacity, Adobe Audition, Logic, Pro Tools, Reaper and GarageBand, as well as transcription tools that prefer uncompressed input.
File size
ClipFit writes 16-bit PCM at the video’s original sample rate. CD-quality stereo uses about 10 MB per minute, so an hour of audio is around 600 MB. Very long videos are rejected before processing starts, with a suggestion to use MP3 instead.
Syncing audio from a separate recorder
When you record sound on a separate microphone or recorder, the camera’s own audio is used to line up the two in an editor. Extracting the camera track as WAV gives you a clean reference file without having to import the whole video.
WAV is also the safest choice for speech recognition and subtitle tools, which tend to give the most accurate results with uncompressed audio.
Private by design
ClipFit processes your video inside your browser using FFmpeg compiled to WebAssembly. The file is never uploaded, so there’s no waiting for transfers and no copy left on a server. Once you close the tab, nothing remains.
Questions
Is the WAV better quality than the video’s audio?
It’s identical to the decoded audio track. WAV prevents further loss, but it can’t add detail that the original compressed track didn’t have.
What sample rate is used?
The same as the source, usually 44.1 kHz or 48 kHz. Nothing is resampled.
Can I extract WAV from several videos?
Yes. Select up to 20 videos and each gets its own WAV download.
Which editors can open the WAV file?
Practically all of them, including Audacity, GarageBand, Logic Pro, Adobe Audition, Reaper, Pro Tools and the audio tracks of video editors like Premiere Pro and DaVinci Resolve.
