Subterranean Sonar

Number six in my series of FM synthesis experiments is a grainy, low frequency stomach growl that makes me imagine subterranean seismic activity. For this example I played a randomized patch three times at different positions on the keyboard while exploring the patch.

One word of warning: I have not filtered out any subsonic frequencies or tested the audio on equipment that is capable of producing them.
