Download the M4A
Just the sound, no video.
Why save the audio as M4A
Only the soundtrack is processed, so this is much faster than converting the video, and the picture is left out.
M4A is AAC audio in an MP4-style file, Apple's usual audio format (Voice Memos, GarageBand, iTunes). It sounds a little better than MP3 at the same size.
For speech, like a talk or interview you'll transcribe, a low bitrate is plenty; for music, pick a higher one.
