already found it and used it, but did some more research...
packed/unpacked the wave files, made programs for generating
frequencies, playing them, saving them, and plotting the files as
amplitude as a function of time.

Yeah, I know ;-) I expected the OP to discover that really quick,
and enjoy an early tidbit of success, maybe printing the parameters
in a pretty format to his taste ;-)

You can do this with one function call - wave.Wave_read.getparams()
import wave
wave.open("filename","b")
wave.Wave_read.getparams()

I used it to create an echo effect toy for my grandson by reading existing .wav sound effect files and adding delayed reduced-aplitude feeback to itself and writing another file. Parameters were distance in feet to a reflecting wall (assuming 1000 ft/sec sound speed ;-) and relection volume factor. Not hard. Maybe make yourself a little utility first that will show you the specs for any .wav file (i.e., sampling frequency, bytes per sample, channels, etc.) I don't recall at the moment whether you have to deal with signed or offset amplitude values, but it won't be hard. This won't play the sounds though. Regards, Bengt Richter -- http://mail.python.org/mailman/listinfo/python-list

generating audio signals
I'm running linux and would like to generate specific frequencies and play them(in OSS) or alternatively save them as wav files, how should I accomplish this? Using python to play and generate is not strictly necessary, as long as I can invoke the command from python. I know for example xmms can do this, but I want a command-line only solution. thanks -- http://mail.python.org/mailman/listinfo/python-list
