Graphing the pitch (frequency) of a sound

http://stackoverflow.com/questions/4708613/graphing-the-pitch-frequency-of-a-sound

But I need to show the audio's pitch not amplitude. Fast Fourier transform appears to get the pitch but it needs to know more.. just an efficient algorithm for calculating the discrete Fourier transform DFT see http en.wikipedia.org wiki Discrete_Fourier_transform.. transform DFT see http en.wikipedia.org wiki Discrete_Fourier_transform . The basic DFT algorithm is much easier just two..

http://stackoverflow.com/questions/962426/processing-audio-data-using-fourier-transforms-in-java

Audio Data using Fourier Transforms in Java I'm trying to process audio data. I'm working.. N data samples to a function that calculates the Discrete Fourier Transform or Fast Fourier Transform which is more efficient.. that calculates the Discrete Fourier Transform or Fast Fourier Transform which is more efficient . I've read documentation..

Fastest Gaussian blur implementation

domain is equivalent to multiplication in the frequency Fourier domain. This means that you can take the Fourier transform of.. frequency Fourier domain. This means that you can take the Fourier transform of the image and the filter multiply the complex results.. multiply the complex results and then take the inverse Fourier transform. The complexity of the FFT Fast Fourier Transform..
