[Portaudio] Cannot find a ease hello world FFT or what ever frequency finder.

As long as you only need to detect specific frequencies, the Goertzel algo should be ok: http://stackoverflow.com/questions/11579367/implementation-of-goertzel-algorithm-in-c

Applying the algo to the correct portions of wav file is left as an exercise for the reader ;)

Is there a c/c++ software that looks for a certain frequency in a wav file? For example, like a c/c++ function that will return the strength 440Hz frequency between 10 seconds and 12 seconds in a 60 second wav file.
