[linux-audio-user] Digital audio files for hardware verification

[Paul Winkler]

Awk is powerful and concise, but it's not my friend - I can never remember how
the heck it works ;-)

I'd probably do like Paul D. suggests and use existing tools - e.g.
find something
to generate an appropriate soundfile, then feed it through sox.
But just for fun, here's something silly I just whipped up:

$ ./sine_hex.py
Usage: ./sine_hex.py frequency [sampling rate] [bits]
Print one cycle of a sine wave of approximately the
given frequency.
Values given in hex with *bits* precision at *sampling rate*.
Default sampling rate is 44100. Default bits is 16.

And here's the source. Most of it is argument handling :-)
