(see examples/array/

--- - 2004.9.29
- now able to write audio files (wav, aiff, raw)
(try and concurrently with any other shreds
to record to disk)
- STK file endian is now observed (more things should work
on little endian systems)
- added 4 "special" built-in sound samples
"special:glot_pop" - glottal pulse (flat)
"special:glot_ahh" - glottal 'ahh' pop
"special:glot_eee" - glottal 'eee' pop
"special:glot_ooo" - glottal 'ooo' pop
(see/listen to,,
- all bulit-in sound samples now loadable from both WaveLoop and sndbuf
- (win32) sndbuf now properly loads wav aiff
new examples:
- - stooges, evolved
- - run this concurrently to write audio to file
(also try with -s flag for file out, no real-time audio)
- - same as rec, but writes to different file every time,
for sessions

- all of STK is now in ChucK!
- new examples (see below)
