invert_stft#

hmc_mir.tsm_tools.tsm_tools.invert_stft(S, hop_length, window)[source]#

Reconstruct a signal from a modified STFT matrix.

Parameters:

  • S – modified STFT matrix

  • hop_length – the synthesis hop size in samples

  • window – an array specifying the window used for FFT analysis

Returns:

A time-domain signal y whose STFT is closest to S in squared error distance.
