wsola

Waveform Similarity Overlap-add. Translated from TSM Toolbox.

wsola(x, s, win = "hann", winLen = 1024, synHop = 512, tol = 512)

Arguments

x

an audio signal

s

a scaling factor or a list of two vector with anchor points

win

window function. Default is 'hann' for hanning window. Can also be a custom window supplied as a vector

winLen

window length

synHop

synthesis window hop size

tol

tolerance for overlap delta

Value

retimed audio signal as vector
