Hi I'm looking for a library to detect when ball hit in a audio of a tennis match. I read this topic but I think there is a suite library for this job. please guide me tanx

A: 

I doubt that there is a library for this specific task. You can probably implement something from scratch though, using a sliding FFT to generate a power spectrum and some kind of simple template matching in the frequency domain.

Would you mind introducing me that library?

@Ali: which library ? There are plenty of FFT libraries out there, if that's what you mean, e.g. FFTW: http://fftw.org or Kiss FFT: http://sourceforge.net/projects/kissfft
