LTFATPY: Towards Making a Wide Range of Time-Frequency Representations Available in Python
LTFATPY is a software package for accessing the Large Time Frequency Analysis Toolbox (LTFAT) from Python. Dedicated to time-frequency analysis, LTFAT comprises a large number of linear transforms for Fourier, Gabor, and wavelet analysis along with their associated operators. Its filter bank module is a collection of computational routines for finite impulse response and band-limited filters, allowing for the specification of constant-Q and auditory-inspired transforms. While LTFAT has originally been written in MATLAB/GNU Octave, the recent popularity of the Python programming language in related fields, such as signal processing and machine learning, makes it desirable to have LTFAT available in Python as well. We introduce LTFATPY, describe its main features, and outline further developments.
