Analyzing .WAV files

indienick · 08-16-2006, 11:09 AM

I'm looking to build an audio comparison program - as for which language to write it in, it doesn't matter.

How do you analyze a WAV file frame by frame, and return the frequency level?

I'm looking to write a DSP sound analysis program for linux, because there doesn't seem to be anything half-decent. The best thing I can find (and runs flawlessly in Wine) is DADiSP.

What I want from this program is simply for it to analyze each frame of the WAV file, and return the value at that audio frame in plain text.

Any help on the matter would be greatly appreciated.

the first thing to do would be to learn the format of wav files

wotsit is a good place for that

I'm curious to understand how a wav file can be analysed frame by frame, given a frame apply to video, and wav is a sound format.

another good reason to study the file format
