Extension for Chrome to download videos as MP3?

[Berryracer]

Is there an extension for Chrome that allows the user to download a video he is watching directly as an MP3 without having to go to other sites to convert it there?

Basically what the user wants is to extract the audio directly from the video in a downloadable format

Keepvid.com used to allow you to just save the audio from a vid clip. Haven't used them in a long time though.
