PyWavelets - Wavelet Transforms in Python. Wavelet transforms are time-frequency transforms The mexican hat wavelet “mexh” The Morlet wavelet “morl” The complex Morlet wavelet (“cmorB-C” with floating point values B, C) The Gaussian wavelets (“gausP” where P is an integer between 1 and and 8) The complex Gaussian wavelets (“cgauP” where P is an integer between 1 and 8) The Shannon wavelets (“shanB-C” with floating point values B and C) The frequency B-spline PyWavelets is a free Open Source library for wavelet transforms in Python. Aug 4, 2025 · PyWavelets What is PyWavelets Documentation Installation State of development & Contributing Contact License What is PyWavelets PyWavelets is a free Open Source library for wavelet transforms in Python. It introduces the main function cwt alongside several helper function, and also gives an overview over the available wavelets for this transfom. Lee, Ralf Gommers, Filip Wasilewski, Kai Wohlfahrt, Aaron O’Leary (2019). Note cwt and related functions in PyWavelets have some known issues; you may be interested in trying the cwt implementation in ssqueezepy, which is substantially faster and may also be more accurate. 0: scipy. This module requires NumPy, SciPy Signal extension modes # Because the most common and practical way of representing digital signals in computer science is with finite arrays of values, some extrapolation of the input data has to be performed in order to extend the signal before computing the Discrete Wavelet Transform using the cascading filter banks algorithm. In addition, the module also includes cross-wavelet transforms, wavelet coherence tests and sample scripts. 12 and will be removed in SciPy 1. Wavelets are mathematical basis functions that are localized in both time and frequency. We recommend using PyWavelets instead.
