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,

Hey,

I am after numerical values for things such as:
  • Loudness (RMS)
  • Brightness
  • Pitch
  • Bandwidth
  • Average frequency
  • Harmonicity
But I want to research several different characteristics to find out which ones work best for the classification problem. At the moment, I am hoping to differentiate between composers.

Can you tell me more about this "AudioUnits"? I have downloaded the SDK off the apple website - but am still new to programming on the Mac. Are there any examples of using this SDK to open wav files and get parameters from them??

Any help is appriciated!

Thanks,
Chris
