Sound card input

[Nick]

Are there any good C++ libraries that let me input bytes from a sound
card's line in? I've tried a few, but they always seem to be fubar.

I need to be able to make distinctions between sounds input from a
radio connected to the sound card thru the line in, probably using the
sine wave formula of the input.

They are not behavers defined in ISO C++.
You may need to consult some platform-dependent implemetion,
for exampe, MS VC.
