  3. Preview and download the WAV.

MP4, M4A and WAV in brief

MP4 is a container format used for most videos from phones and cameras. Its audio is usually compressed with AAC. M4A is the same container with only audio inside; iPhone voice memos and many music downloads use it. WAV stores audio uncompressed, which makes it larger but universally accepted by audio editors, DAWs and transcription tools.

Converting MP4 to WAV decodes the AAC audio into plain samples. The sound quality matches the original track; it can’t add back detail the AAC compression removed, but it won’t lose any more.

Frequently asked questions

Which sample rate should I choose?

44.1 kHz is CD quality and works everywhere. 48 kHz matches most video. 16 kHz mono is ideal for speech-to-text services and makes much smaller files.

How big will the WAV be?

About 10 MB per minute for 44.1 kHz stereo, or about 2 MB per minute for 16 kHz mono.

Are my files uploaded to a server?
