Spectrogram processing

This sub-package provides functions to process signals in the time-frequency domain, such as the calculation of the Short-Time Fourier Transform (STFT) and Inverse STFT (ISTFT).

Stft([signal, fft_size, window_type, ...])	Compute the short-time Fourier transform (STFT) of a signal.
Istft([stft])	Compute the inverse short-time Fourier transform (ISTFT) of a signal.
