is there any way to extract or record the audio off a youtube video?

There are ways. If you’re on a Mac, Audio Hijack or WireTap will do this. I’m not sure how you’d do it on a PC, but it is definitely possible.

I have both so I’ll check those programs out ty

If you have QuickTime Pro, it will open a .flv file (use keepvid or something like that) and then you can Export audio-only to .mp3 or .aiff (or lots of other formats). VLC (videolan) should also be able to.

here is FLV audio extractor
FLV

and you can download the FLV video file very easy with firefox plugins. just search the add-ons

and here is RMC, its awesome and does alot…
Replay Media Catcher

check them both out and tell me if im understanding your question cheers

The easiest way is to copy the url of the youtube video to zamzar.com/url and select MP3 as the output format. Zamzar will automatically e-mail you the song download link once it has finished converting the audio.
