Hello, Wo can help me with C/C++ source from FFT or DSP or other filter function''s for analyzing analog audio waveforms? Thanks

I try to look at this site, but i can get access to it?
Do you now some way to get in?

Erm - DSP quite distinctly stands for Digital Signal Processing. If you''re looking for tools to analyze analog signals, you''ll either need to convert them to a digital form first (sample them) or use appropriate hardware (some analog DSP board) in which case I personally cannot help you...

If you want to use someone else''s code, Google will most likely help you out, although I suggest finding a book, which would first explain the method to you and then provide you with the source code. To find a book that would contain what you''re looking for, go to a book store and browse through DSP books (preferably for beginners) - these usually explain things in quite some depth. You might also look for a book called A Scientist and Engineer''s Guide to DSP, which is available online for free (it''s ~600 pages; chapters 12-20 deal with everything you might be looking for).

If you''re going to be doing some serious coding, you may want to check out http://www.fftw.org/ as you''d be hard pressed to find faster FFT code. Hope it''s useful!
