100 periods have been collected from a 3 dimensional periodic signal. The wavelength slightly varies. The noise of the wavelength follows Gaussian distribution with zero mean. A good estimate of the w
I have FFT outputs that look like this: At 523 Hz is the maximum value. However, being a messy FFT, there are lots of little peaks that are right near the large peaks. However, they\'re irrelevant,
I read that several DSP cards that process audio, can calculate very fast Fourier Transforms and some other functions involved in Sound processing and others. There are some scientific problems (not m
I\'m trying to write a simple tuner (no, not to make yet another tuner app), and am looking at the AurioTouch sample source (has an开发者_JAVA百科yone tried to comment this code??).
this question is most relevant for users with experience using the JTransform package for Fast Fourier Transforms. I\'m attempting to eventually create an equalizer as part of a larger realtime audio
I need to implement an efficient version of an image convolution with non-separable kernels (so CUDA\'s sdk is useful just for the FFT example, but it is clearly stated that it works great only for bi
I\'m studying the code behind the convolutionFFT2D example of the Nvidia CUDA sdk, but I don\'t get the point of this line:
FFT and changing frequency and vectorizing for loop Greetings All I can increase and decrease the frequency of a
I am new to threading building blocks and trying to encode the FFT algorithm in TBB to get some hands on experience. In case of this algorithm i can only parallelize the innermost loop. but by doing s
I use fftwpp to transform both my data and my convolution kernel into the fourier space, multiply them together like in a scalar prod开发者_JAVA百科uct and convert them back to the real space. When I
