Is it possible to extract only the audio from one of the concerts I downloaded? I would like to take Hammersmith '75 and have the concert music converted to MP3s so I can listen to them on my MP3 player. Any ideas? Thank you.
There's a program called Electronic Cosmo's MPEG Suite, which I use to decode stuff and sometimes for encoding MP3s... and it should be able convert the file to audio. The only problem is, mpeg movie audio generally seems to come out at the wrong speed so you'd need to be able to adjust the speed in a wav editor I think. link
It's completely free.
