-The "audio playpen" is intended as a collection of analog-style modules
-for people who just want to patch stuff together without worrying much
-about how Pd works.  A fair amount of work would be needed to make this into
-a more usable package than it is now.  At the moment it's unclear what
-should be the relationship between this collection, the "examples," and
-the "tools".
-
-At the very least there should be oscillators and envelope generators here,
-and audio-rate db/rms/dB, mtof, ftom conversion...
