video-sound splitting program

does anybody know any program that splits the sound from videos ? it would be very useful, as i need it for some youtube videos. i think i had one, it was called... something with "studio"... so post the name of the program and if you can a link, too. thank you...

pinnacle studio, but its a load of crap.The only free video editing software I know is virtualdub

thanks, but does anybody know any program that works directly with mp4 archieves? (if i convert it the quality gets ruined)

virtualdub will work with anything you have codecs for.

nop, it says it doesnt support mp4

mp4 pisses off like all video editors because it's a really annoying format to edit with.

WavePd (NCH)...
Audacity...
Also, convert MP4 with Xilisoft Video Converter or Youtube Downloader..
