tf.signal.inverse_stft_window_fn(

name=None
)
Defined in tensorflow/python/ops/signal/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.
Args:
frame_step
: An integer scalarTensor
. The number of samples to step.forward_window_fn
: window_fn used in the forward transform,stft
.name
: An optional name for the operation.
Returns:
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.
