WebAug 21, 2013 · The FFT is a O (NlogN) algorithm, where N is the number of points. While it may not be as dramatic as the naive DFT, the increase in N will start to bleed your processor, especially if you're working in the confines of an embedded system. Secondly, when you increase N, you're gaining frequency resolution while you're losing time resolution. WebPyWavelets is free and Open Source wavelet transform software for the Python programming language. It combines a simple high level interface with low level C and Cython performance.
