ISTFT Inverse Short-Term Fourier Transform using a sine window.
- Parameters
- X
array
, 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
array
, shape (Tx,) vector containing the inverse STFT signal
Examples
x = istft(X)
x = istft(X, tstep)
