I know a WAV is sound, but I don't know a more powerful (or appropriate) encoder. I have a CD with music on the left channel and voices on the right. I can rip that to an interleaved stereo WAV file or a down-mixed mono WAV. How might I set it to only take the left channel out? Or another project I should go to?
