This is a toolbox of time-frequency analysis based on Python.
It includes Short Time Fourier Transform (STFT), S-transform (ST), Wigner-Ville distribution(WVD), and Continuous Wavelet Transform (CWT).
In response to the increasing demand for time-frequency aggregation, synchronous squeezing(Sq) and synchronous extraction(SET) have been added to the toolbox for SqSFTF and SEO-S.
[1] Python-based time-frequency analysis method (excluding CWT).
