tf.compat.v1.signal.overlap_and_add

tf.signal.overlap_and_add(
    signal, frame_step, name=None
)

Adds potentially overlapping frames of a signal with shape [..., frames, frame_length], offsetting subsequent frames by frame_step. The resulting tensor has shape [..., output_size] where

output_size = (frames - 1) * frame_step + frame_length

Args
signal	A [..., frames, frame_length] Tensor. All dimensions may be unknown, and rank must be at least 2.
frame_step	An integer or scalar Tensor denoting overlap offsets. Must be less than or equal to frame_length.
name	An optional name for the operation.

Returns
A Tensor with shape [..., output_size] containing the overlap-added frames of signal's inner-most two dimensions.

Raises
ValueError	If signal's rank is less than 2, or frame_step is not a scalar integer.
