Separating the audio does not re-encode the picture, because the picture is discarded rather than converted. That is why this takes seconds on a file that would take minutes to transcode. Their caps exist because every conversion runs on a machine they rent. Yours runs on the machine in front of you.

  1. 1

    Where your MP4 came from

    An MP4 is what a phone, a camera and every video site produce. Its audio track is AAC and it is a fraction of the file.

  2. 2

    Why you are converting it

    Nothing refuses an MP4. What refuses is the situation: a podcast host, a transcription service or a music player that wants sound and not a picture. WAV is uncompressed samples with a forty four byte header. Editors, samplers and anything that has to process rather than play the audio want it.

  3. 3

    What it costs

    Nothing further is lost going into WAV, because nothing is thrown away. What an earlier encode discarded is still gone, and a large file does not bring it back.
