In this video - http://www.youtube.com/watch?v=0y0v-aY9RrI I need the background music (mp3) minus the talking from 0:15 to 0:30. If volume can be increased, that would be good as well. PM ME!
You can use http://www.youtube-mp3.org/ to extract the audio, but removing voices will be more difficult. You will need an audio editing program. I would guess that there is audio software used to make karaoke. http://download.cnet.com/Vocal-Remover-Winamp/3000-2169_4-10254947.html (I have never used that or any similar software so I can't help)
Hey - I posted a site with a link the other day but it got pulled because I inserted the link. I guess I don't have enough posts to include links. Anyway, you can download VideoSoft, which will either rip the whole YouTube video or just the MP3. It's freeware. Google DVDVideoSoft and you'll get the link. After you rip it, you can edit the MP3 with any sound editor. There's also a Firefox add-on you can use to download videos and then you can edit in a movie editor. I use Sony Vegas Pro for video editing but it costs about $100 - I do a lot of video so it was worth it for my business.
