I want to develop musical notes detector as my degree project and I want to do it from scratch. I have written code for ".wav" file which extracts all info from that audio music file and gives me a...

So I'm trying to write the Discrete Fourier Transform in C to work with real 32-bit float wav files. It reads in 2 frames at a time (one for each channel, but for my purposes I'm assuming they are ...

Possible Duplicate: How to get Frequency from FFT result I am somehow confused with the x axis of fft(DFT) command in Matlab. When we do a fft command for a signal which has sampled i...

I am working on optimizing a data flow task, I thought I will see which component takes how much time. I got these tasks: How should I find out how much time each took? Except time if i can find...

For instance, consider the DFT or DCT. Precisely, what would be the differences between an image transformed by sub-blocks, and an image transformed whole? Is the resulting file size smaller? Is th...

I'm trying to understand a few things about neural networks. First, after looking around on the web, it seems that there is no way to compute a (discrete) Fourier transform through a neural n...

I am new in OpenCV and image processing algorithms. I need to do inverse discrete fourier transformation in OpenCV in C++, but I don't know how. I searched over internet and I didn't find answer. I...

I am currently trying to write some fourier transform algorithm. I started with a simple DFT algorithm as described in the mathematical definition: public class DFT { public static Complex[] Tran...

I've been playing around a little with the Exocortex implementation of the FFT, but I'm having some problems. Whenever I modify the amplitudes of the frequency bins before calling the iFFT the res...
