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

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

Parameters
Xarray, shape (…, wsize / 2 + 1, n_step)

The STFT coefficients for positive frequencies.

tstepint

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

Txint

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

Returns
xarray, shape (Tx,)

Array containing the inverse STFT signal.
