fade rate both linear & equal power
* shuffle - a no-repeat random generator, outputs numbers within a set range
* pan~ - equal power stereo panning
* system - sends a system message to the console
* ln~ - natural log + inverse
* rec2pol~ - convert rectangular coordinates to polar eg. can be used
to convert sine & cosine rfft~ output to phase & magnitude
* pol2rec~ - inverse of rec2pol~
* getenv - Sends value of an environment variable argument on bang
