Does any one know where I can get a good free tool that takes the audio from video. I found some but they only do 1/2 of what you want or up to 30 seconds.
Although that works, there might be some loss of quality since your method probably has to undergo some digital->analog->digital conversions... as well as be done in real-time [the full-duration of the media].I used to do it using plain old Windows sound recorder. Have that recording in the background at the same time as the video is playing. It seemed to work OK for me. I used this to pull some songs off of movies on DVD.
While this also works, there's now the possibility of introducing electrical noise (e.g., hum) into the audio recording. This must also be done in the full-duration of the media.I've always just used Audacity. I take a cord and connect the headphone output and then put the other end in the microphone input. It has worked fine for me every time so far.
