Remove impulsive noise from input audio.

Samples detected as impulsive noise are replaced by interpolated samples using autoregressive modelling.

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.

o

Set window overlap, in percentage of window size. Allowed range is from 50 to 95. Default value is 75 percent. Setting this to a very high value increases impulsive noise removal but makes whole process much slower.

a

Set autoregression order, in percentage of window size. Allowed range is from 0 to 25. Default value is 2 percent. This option also controls quality of interpolated samples using neighbour good samples.

t

Set threshold value. Allowed range is from 1 to 100. Default value is 2. This controls the strength of impulsive noise which is going to be removed. The lower value, the more samples will be detected as impulsive noise.

b

Set burst fusion, in percentage of window size. Allowed range is 0 to 10. Default value is 2. If any two samples deteced as noise are spaced less than this value then any sample inbetween those two samples will be also detected as noise.

m

Set overlap method.

It accepts the following values:

a

Select overlap-add method. Even not interpolated samples are slightly changed with this method.

s

Select overlap-save method. Not interpolated samples remain unchanged.

Default value is a.
