    capture the audio while playing the video, and trim as needed. I always add a little padding before and after as it is simple to remove excess bits, but you cannot add once you are done playing the source. I would go with a WAV* file then convert to the lossy codec of choice, as in Ogg-Vorbis, MP3, Wavpack, etc. You can also save the file as straight MP3 and skip the middle step.
    A good free option is Audacity, and of course the final quality will only be as good as the source material.

    *Personally I save a master file in a lossless codec (Wavpack Hybrid these days), and then convert the WAV file to whatever lossy codec I need depending on the final use.

    As an alternative you can use ffmpeg to re-encode the audio track directly. Something like:

    ffmpeg -i myvideo.file -vn -c:a mp3 mynew.mp3

    Would do what you're looking for. It requires a bit of command line jiggery-pokery but nothing too complicated. The advantage to this is that you don't have to sit through it in real-time, and you don't have to worry about mucking up your stream by playing something else. You can just let it strip and encode in the background.

    Should also note that ffmpeg supports a wide variety of formats for both input and output, including wavpack.
