MP4 to WAV ConverterExtract the sound from an MP4 video as a WAV file for editing. WAV is uncompressed, so every audio editor and digital audio workstation opens it instantly and no further quality is lost while you work.
MP4 vs WAV: what changes
MP4 audio is compressed (usually AAC) to keep video files small. WAV stores the decoded sound as plain, uncompressed samples. That makes WAV large, about 10 MB per minute for stereo, but ideal for cutting, cleaning up noise, mixing and mastering. For listening or sharing, MP4 to MP3 gives a much smaller file.
When to convert MP4 to WAV
Use it before editing a video’s sound in Audacity, Adobe Audition, GarageBand, FL Studio or Reaper, for transcription software that prefers WAV, or when a client asks for uncompressed audio.
Before you convert
WAV does not improve the sound: it is an exact copy of what the MP4 contained, just uncompressed. The WAV is saved as 16-bit PCM at the video’s original sample rate, and the file will be much larger than the MP4’s audio track.
Common problems and fixes
The WAV is enormous
WAV is uncompressed, so even a 10-minute video gives about 100 MB of audio. Choose MP4 to MP3 if you only want to listen.
My editor wants 48 kHz
The WAV keeps the sample rate of the video, which is 48 kHz for most phone and camera videos, the standard for video editing.
There is a delay between audio and picture in my edit
The WAV covers the full video from the first frame, so line it up with the start of the clip in your editor.

Frequently asked questions
Why is the WAV so large?
WAV is uncompressed. One minute of stereo audio at 44.1 or 48 kHz is about 10 MB. That is normal.
Will WAV keep the original sample rate?
