Generates a window function that can be used in inverse_stft.
tf.signal.inverse_stft_window_fn(
frame_step, forward_window_fn=tf.signal.hann_window, name=None
)
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. |
