mne.time_frequency.istft(X, tstep=None, Tx=None)[source]¶

ISTFT Inverse Short-Term Fourier Transform using a sine window.

Parameters:

Parameters:	X : 3d array of shape [n_signals, wsize / 2 + 1, n_step] The STFT coefficients for positive frequencies tstep : int step between successive windows in samples (must be a multiple of 2, a divider of wsize and smaller than wsize/2) (default: wsize/2) Tx : int Length of returned signal. If None Tx = n_step * tstep
Returns:	x : 1d array of length Tx vector containing the inverse STFT signal

X : 3d array of shape [n_signals, wsize / 2 + 1, n_step]

The STFT coefficients for positive frequencies

tstep : int

step between successive windows in samples (must be a multiple of 2, a divider of wsize and smaller than wsize/2) (default: wsize/2)

Tx : int

Length of returned signal. If None Tx = n_step * tstep

Returns:

x : 1d array of length Tx

vector containing the inverse STFT signal
