Wav -> Dsp -> Components, Using DSP to take components from a .wav Options

[tingleychris]

Hi,

I am developing an MLP Artifical Neural Network application (www.etingley.com/uni), but am now at the stage of using a DSP toolkit to remove certain traits (components) of a .wav file.

I am developing in C++ in XCode on Panther.

Can anyone suggest a decent toolkit to use that will easily allow me to give it a wav and extract numerical components?

Best Regards,

FFTing won't help you much, FFT is an amazing tool (as you probably have noticed in my own FFTea!) but it is very very limited by :
*) it's ambivalence between time resolution and frequency resolution: the bigger the FFT, the more data you need to feed it, and therefore the less frequency resolution you get!
*) lack of resolution at low frequencies. Even with a large FFT, anything even remotely bass-like falls in between FFT bins and is pretty much not measurable.

Have a spin playing with FFTea, you'll quickly learn the limit of the mathematical tool.
