Remove clipped samples from input audio.
Samples detected as clipped are replaced by interpolated samples using autoregressive modelling.
window, w
Set window size, in milliseconds. Allowed range is from 10 to 100. Default value is 55 milliseconds. This sets size of window which will be processed at once.
overlap, o
Set window overlap, in percentage of window size. Allowed range is from 50 to 95. Default value is 75 percent.
arorder, a
Set autoregression order, in percentage of window size. Allowed range is from 0 to 25. Default value is 8 percent. This option also controls quality of interpolated samples using neighbour good samples.
threshold, t
Set threshold value. Allowed range is from 1 to 100. Default value is 10. Higher values make clip detection less aggressive.
hsize, n
Set size of histogram used to detect clips. Allowed range is from 100 to 9999. Default value is 1000. Higher values make clip detection less aggressive.
method, m
Set overlap method.
It accepts the following values:
add, a
Select overlap-add method. Even not interpolated samples are slightly changed with this method.
save, s
Select overlap-save method. Not interpolated samples remain unchanged.
Default value is a.
