Convert MP4 to WAV

Drop an MP4 and download its audio track as a 16-bit PCM WAV, at the sample rate and channel count the source used.

What WAV is for

WAV is the format to hand an editor. It carries no codec to decode, so a DAW, a transcription tool, or an analysis script opens it directly, and every edit after this point works from uncompressed samples.

That is the only gain. The AAC track inside the MP4 was lossy before this conversion started, and WAV cannot put back what the encoder removed. Expect roughly 10 MB per minute of stereo audio.

Sample rate

Nothing is resampled here. A 48 kHz video soundtrack, which is what most cameras and screen recorders produce, comes out as a 48 kHz WAV. Use the sample rate converter if a destination demands 44.1 kHz.

Frequently Asked Questions

Why is the WAV so much larger than the MP4?

WAV stores every sample uncompressed. Stereo 44.1 kHz 16-bit PCM runs at about 10 MB per minute regardless of what the source was encoded at.

Does converting to WAV restore quality the video lost?

No. The MP4's AAC track discarded detail when it was encoded, and decoding it to WAV recovers only what survived. The WAV is bigger, not better.

Which bit depth does it write?

16-bit PCM. The full Audio Converter offers 8, 24, and 32-bit.

Why use WAV at all then?

Editors, transcription tools, and DAWs read it without a decoder, and every further edit starts from an uncompressed file rather than adding another lossy generation.
