Hi,
I've been toying recently with the X window test extension (which
allows the user to simulate input events) and I've decided to create a
bigger project that uses it. My project idea would be a unix daemon
that reads data from the sound card, gets the dominant frequency and
then reports a key corresponding to this data.
Unfortunately, I don't know the theory of spectrum analysis and I
don't think I could come up with a high-performance spectrum analyzer
in reasonable time.
So, my question is : do you know a good spectrum analyzer, preferably
written in C that I could modify ?
Regards,
Karim
