tf.contrib.signal.inverse_stft_window_fn

tf.contrib.signal.inverse_stft_window_fn(
    frame_step,
    forward_window_fn=functools.partial(window_ops.hann_window, periodic=True),
    name=None
)

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.

Args:

• 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.

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.
