This will cause distortion and change the shapes of your waveforms, and
introduce extra harmonics. It may be an interesting effect, but it will
change the sound of your beatboxing.

This would be the preferred method.

If you have multiple instruments or voices in the output, you'll be
decreasing the volume globally and throwing off your mix.

Then, you haven't picked the right computer for your composition :)
Really, I don't think compression should be a cpu-expensive process. Plus,
you have only one mic, right?
