It is currently impossible to change the mono/stereo setting for each track. It might be technically possible for vorbis (although not for mp3, I guess) but in any case it does not look like a very good idea to me. When liquidsoap decodes an mp3 file that contains mono audio, it should copy the mono track on both left and right channels. If you can check on a minimal config and confirm that this is not the case, I think we should declare it a bug, so please file a ticket. Finally, there are operators for converting from mono to stereo, I think it's simply called mono2stereo(). But it'll treat every track: it is meant for an uniformly mono stream, not for a stream where isolated tracks are mono. > Question #2 > I've noticed that on long tracks (30 minute + tracks) that right before the > track ends there is a very short silence (usually <1 second or less).

You can try without the crossfade, maybe. Are you sure that it's not the file. To run that sort of tests, you might be able to use the accelerate() operator that removes the middle of a track; this is a hack that might not work in some situations, but which I designed some day when running tests on transitions.
