How to extract semi-precise frequencies from a WAV file using Fourier Transforms
- by Seisatsu
Let us say that I have a WAV file. In this file, is a series of sine tones at precise 1 second intervals. I want to use the FFTW library to extract these tones in sequence. Is this particularly hard to do? How would I go about this?
Also, what is the bast way to write tones of this kind into a WAV file? I assume I would only need a simple audio library for the output.
My language of choice is C
