OverlapAdd¶
streaming mode | Standard category
Inputs¶
frame
(vector_real) - the windowed input audio frame
Outputs¶
signal
(real) - the output overlap-add audio signal
Parameters¶
frameSize
(integer ∈ (0, ∞), default = 2048) :the frame size for computing the overlap-add process
gain
(real ∈ (0., ∞), default = 1) :the normalization gain that scales the output signal. Useful for IFFT output
hopSize
(integer ∈ (0, ∞), default = 128) :the hop size with which the overlap-add function is computed
Description¶
This algorithm returns the output of an overlap-add process for a sequence of frames of an audio signal. It considers that the input audio frames are windowed audio signals. Giving the size of the frame and the hop size, overlapping and adding consecutive frames will produce a continuous signal. A normalization gain can be passed as a parameter.
Empty input signals will raise an exception.
