I have this live video of a michelle branch singing all you wanted, and wanted to save the song so i could listen in the car. Is there a program where i could just get the audio from the video?
There are programs out there that can extract audio from different a/v sources. What media format is the video?
If it's digital, check out www.vcdhelp.com where you should be able to find a program to do what your asking. Let me know if you can't find what your looking for.
P.S. You might be able to use your sound card with "What you hear" as a recording source.
I don't know of any off of the top of my head, but there are programs that will take exactly what your sound card is supposed to be playing and it records that sound to a file as you play your media. I am sure there are other recording methods as well.
