Hi,

can someone give me some pointers on where I can learn about writing
code to sample data from the microphone port on a sound card on a
system running RHL 9?

Of course we have apps which can record audio from the mic, but I want
to sample the microphone during some real time intervals and try to
detect several tones.

thanks much,

sorry if this is the wrong group.
