Why choose WAV output?

WAV is an uncompressed audio format, which makes it useful for editing, cleanup, voice work, podcast preparation, and moving audio into apps like Audacity or video editors. WAV files are larger than MP3 or M4A, so choose MP3 or M4A when you only need a small file for sharing.

Does WAV improve MP4 audio quality?

Converting MP4 to WAV does not magically improve the original audio. Most MP4 files already contain compressed audio. WAV gives you an editing-friendly file without adding another lossy compression step, but the final quality still depends on the audio inside the source video.

Supported video formats for WAV extraction

Upload MP4, MOV, M4V, MKV, AVI, WEBM, 3GP, MPEG, MTS, or TS videos and export the audio as WAV. Videos can be up to 1GB and 3 hours long in the current beta.

Can I convert MOV, WEBM, or MKV to WAV?
Yes. MediaReady accepts common video formats including MP4, MOV, M4V, MKV, AVI, WEBM, 3GP, MPEG, MTS, and TS.
Is WAV better than MP3?

Will converting MP4 to WAV improve audio quality?
