Generating Multichannel Audio

Set up continuous audio generation using multiple audio channels. The signal, a sample of Handel's "Hallelujah Chorus", is broken up into contiguous segments and played back in two parts. The first part of the example plays each segment on a single speaker and a sub-woofer. The second part plays each segment on a different set of speakers (a choir of voices).
