Drop a video or audio file
MP4, MOV, WebM, MP3, WAV or M4A. The file is read on this page and never uploaded.
When you need the sound alone
- Editing a podcast or voice-over from a video recording in a DAW such as Audition, Logic or Reaper.
- Sending a transcription service or a translator the audio instead of a large video file.
- Keeping the sound of a talk or lesson to listen to later.
About the WAV file
The file is 16-bit PCM WAV, which every editor, DAW, player and transcription tool opens. It is uncompressed, so nothing is lost on the way out, and it is larger than an MP3: about 10 MB a minute in stereo, half that in mono. Mono suits speech and halves the size; As recorded keeps the left and right channels.
The sample rate is the one your browser decodes at, usually 48 kHz, which is the rate video sound is recorded at.
Captions from the same file
Caption it in the studio opens the same video in Cuecaps, which finds every word, times it and animates word-by-word captions, or exports SRT, VTT and ASS subtitles. It renders in your browser too.
Questions
Is my video uploaded?
No. The browser reads the sound out of the file on this page and the WAV is saved with a normal download.
Which formats work?
Whatever your browser plays: MP4 and MOV with AAC sound, WebM, and audio files such as MP3, M4A and WAV. Chrome and Edge also read most MKV files.
Can I get an MP3?
This page saves WAV, which keeps the sound exactly. Any audio app, including the free Audacity, converts it to MP3 in one step.
