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

I'm trying to link my project with fftw and so far, I've gotten it to compile, but not link. As the site said, I generated all the .lib files (even though I'm only using double precision), and copied them to C:\Program Files\Microsoft Visual Studio 9.0\VC\lib, the .h file to C:\Program Files\Microsoft… >>> More
How to extract frequency information from samples from PortAudio using FFTW in C

Hi all, I want to make a program that would record audio data using PortAudio (I have this part done) and then display the frequency information of that recorded audio (for now, I'd like to display the average frequency of each of the group of samples as they come in). From some research I've done… >>> More

FFTW 2.x builds a .la file (under fftw/.libs directory). I think I need a .so file to link to. (I am not sure, because I am a gcc newbie). >>> More

Confusion testing fftw3 - poisson equation 2d test

as seen on Stack Overflow - Search for 'Stack Overflow'
I am having trouble explaining/understanding the following phenomenon: To test fftw3 i am using the 2d poisson test case: laplacian(f(x,y)) = - g(x,y) with periodic boundary conditions. After applying the fourier transform to the equation we obtain : F(kx,ky) = G(kx,ky) /(kx² + ky²) (1) if… >>> More
