[microsound] Pirthorexia

[Charlie DeTar]

Uploaded my pi day contribution.

Pirthorexia -- unhealthy obsessive diet of pi.  Sine waves (what else --
pi at work), triggered with a density proportional to one period of a
cosine curve 3 minutes and 14 seconds long.  Every tone is 3.14 seconds
long, and over that interval modulates its frequency in a small sine
curve.  No tone repeats (tones include every 1/48th octave between 27.5
Hz and 21096.96 Hz).  Intervals between subsequent notes are taken from
subsequent digits of pi (though following the no-repeat rule).  Panning
is determined by digits of pi (0 == far left, 9 == far right).
Generated in python (pi-thon).

Audacity's ID3 export did not work with the repository; the linux "id3"
command worked.
