The [simple_sound] code will probably go into my ch 3 at <url:

I haven't yet discussed trig functions, and maybe /with/ changes suggested
by you?
def _append_as_big_endian_int16_to( a, i ):
if i < 0:
i = i + 65536
assert( 0 <= i < 65536 )
a.append( i // 256 )
a.append( i % 256 )
data = array.array( "B" ) # B -> unsigned bytes.
Do you know that array.array() supports 16 bit signed integers?
Yes. I used bytes since that seemed to be what [wave] required. But I tested now
and at least [aifc] handles 16-bit integers fine.
Hm, nice example down the drain...
There's even
a byteswap() method to deal with endianess.
Utility class that may be used to capture output (an instance of this or
any other file like class can be passed as "filename" to
simple_sound.Writer):

class BytesCollector:
Are you reinventing io.BytesIO() here?
Probably. :-) Checking... Yes, I was; thanks!
