    forward_window_fn=functools.partial(window_ops.hann_window, periodic=True),

Defined in tensorflow/contrib/signal/python/ops/spectral_ops.py.

Generates a window function that can be used in inverse_stft.

Constructs a window that is equal to the forward window with a further pointwise amplitude correction. inverse_stft_window_fn is equivalent to forward_window_fn in the case where it would produce an exact inverse.

See examples in inverse_stft documentation for usage.


  • frame_step: An integer scalar Tensor. The number of samples to step.
  • forward_window_fn: window_fn used in the forward transform, stft.
  • name: An optional name for the operation.


A callable that takes a window length and a dtype keyword argument and returns a [window_length] Tensor of samples in the provided datatype. The returned window is suitable for reconstructing original waveform in inverse_stft.
