There is an example at
Analyzing WAV Files with Perl. In this example,
I needed to track the frequency of a tone versus time.
I used Audio::Wav, PDL, and
PDL::FFT.
This code includes various algorithms to track the frequency of a tone. The example graphs are for the algorithm that worked best for my application. I have written some other audio analysis modules, also, so please let me know if you would like more examples. It should work perfectly the first time! - toma In reply to Re: Manipulating Audio Data in Perl
