JTFA(Joint Time Frequency Analysis)

I want to make signal analysis program with C or C++.
I will use joint time frequency analysis, so I must code "Gabor Spectrogram", "STFT(Short Time Fourier Transform)", "Wigner-Ville" and etc.
Who have source of that kind or know related sites ?

Hello Lighter,

For real-discrete FFT's I use FFTW (http://www.fftw.org/). There is platform-independent source code for one-dimensional and multi-dimensional transforms available at this site. The code is, in my opinion, fast. However, it seems like you are looking for a different algorithm. Perhaps the site has some kind of a link.

P.S. This forum might be the wrong place to look for informatin about numerical algorithms. There are mostly questions about Visual C++ programming here.

Good luck.

:)

Sorry about the comment relating to the Visual C++ forum. We are, in fact, on the generic C++ (non-Visual C++) forum page. Had forgotten where I was.

Chris.
