I have an FFT result. These are stored in two double arrays: a real part array and an imaginary part array. How do I determine the frequencies that correspond to each element in these array开发者_如何

I\'m using a FIR filter to oversample audio. It\'s a simple typical windowed sinc, i.e. a sinc function truncated and windowed. As usual it requires past and \'future\' samples to work. in practical t

I want to make a program that detects the note that is being played in front of the microphone. I am testing the FFT function of Naudio, but with the tests that I did in audacity it seems that FFT doe
Can s开发者_运维问答omeone tell me how we can amplify the sound of specific frequency alone?Actually, you don\'t need to use FFTs for this -- digital filters are very computationally efficient, needin
I completed a Window Function kernel in OpenCL. Basically a window function just applies a set of coefficients over another set of numbers piece by piece (Wikipedia explains it better). I was able to
