On behalf of the PyWavelets development team I am pleased to announce the
release of PyWavelets 0.4.0.

As always, new developers interested in wavelets are welcome to join us at:


PyWavelets is a free Open Source library for wavelet transforms in Python.

The main features of PyWavelets are:

- 1D, 2D and nD Forward and Inverse Discrete Wavelet Transform (DWT and
- 1D and 2D Stationary Wavelet Transform (Undecimated Wavelet Transform)
- 1D and 2D Wavelet Packet decomposition and reconstruction
- Approximating wavelet and scaling functions
- Over seventy built-in wavelet filters and custom wavelets supported
- Single and double precision calculations
- Results compatible with Matlab Wavelet Toolbox (TM)

Git (source) repository:
Mailing list:!forum/pywavelets

Highlights of this release

- 1D and 2D inverse stationary wavelet transforms
- Substantially faster 2D and nD discrete wavelet transforms
- Complex number support
- nD versions of the multilevel DWT and IDWT
- modernization/streamlining of the API
