How to convert MP4 to WAV
Extract the audio from a video as an uncompressed WAV file, ready for editing in Audacity, a DAW or transcription software.
- Drop your MP4 file into the box above, or add it from a link.
- WAV is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your WAV file.
To do this from your own code, call the FileForge API with "output_format": "wav".
Good to know
- WAV files are large: about 10 MB per minute of stereo audio.
- Use the sample rate setting if your editor expects 44.1 or 48 kHz.
- Use MP4 to MP3 instead if you just want to listen or share.
About the formats
.mp4
MP4 is the most widely supported video format. It plays on practically every phone, browser, TV and editor, usually with H.264 video and AAC audio inside.
.wav
WAV is uncompressed audio, as recorded. It's the standard for editing and for software that needs raw sound, but files are about ten times bigger than MP3.
Questions
WAV or MP3 for editing?
WAV. It's uncompressed, so editing and re-exporting won't add more compression loss.
