I am trying to compute the frequency of a given sound process through the microphone on the iphone. I\'ve read all the post about FFT (including all apple code examples e.g aurioTouch,SpeakHere), but
I studied the Cooley Tukey algorithm and I understood it. I got everything in the CUDA convolutionFFT2D example till these kernels:
I\'m reading how the cooley tukey method works, but I have a few problems with the following python script:
I have an ArrayList that has Double elements. I want to implement FFT(Fast Fourier Trans开发者_Go百科form) on it. However I don\'t want to take a Java code somewhere else and copy it. How can I find t
At the moment I have no code to help me, but the Fast Fourier Transform probably has something to do with my goal.
I am working on some fourier transform code in matlab, and have come across the following: xx = meshgrid(1:N);
I can re-create a periodic signal using Fourier series expansion using sin and cos waves.But how can I adapt the equation so the equation
Closed. This question does not meet Stack Overflow guidelines. It is not currently accepting answers.
I\'m currently working on this project that implies some DSP skills. I must extract the audio from a movie and then, by analyzing it, I must determine when someone speaks or not, more like an voice ac
I am trying to implement a matlab code that I have that does a 2D convolution. The matlab code first centers the 3x3 kernel in a padded matrix the size of the Image. I do the same thing in my C++ co
