autoregressive modelling.

|

@table @option
|
||||
@item w
|
||||
@item window, w
|
||||
Set window size, in milliseconds. Allowed range is from @code{10} to
|
||||
@code{100}. Default value is @code{55} milliseconds.
|
||||
This sets size of window which will be processed at once.
|
||||
|
||||
@item o
|
||||
@item overlap, o
|
||||
Set window overlap, in percentage of window size. Allowed range is from
|
||||
@code{50} to @code{95}. Default value is @code{75} percent.
|
||||
Setting this to a very high value increases impulsive noise removal but makes
|
||||
whole process much slower.
|
||||
|
||||
@item a
|
||||
@item arorder, a
|
||||
Set autoregression order, in percentage of window size. Allowed range is from
|
||||
@code{0} to @code{25}. Default value is @code{2} percent. This option also
|
||||
controls quality of interpolated samples using neighbour good samples.
|
||||
|
||||
@item t
|
||||
@item threshold, t
|
||||
Set threshold value. Allowed range is from @code{1} to @code{100}.
|
||||
Default value is @code{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.
|
||||
|
||||
@item b
|
||||
@item burst, b
|
||||
Set burst fusion, in percentage of window size. Allowed range is @code{0} to
|
||||
@code{10}. Default value is @code{2}.
|
||||
If any two samples detected as noise are spaced less than this value then any
|
||||
sample between those two samples will be also detected as noise.
|
||||
|
||||
@item m
|
||||
@item method, m
|
||||
Set overlap method.
|
||||
|
||||
It accepts the following values:
|
||||
@table @option
|
||||
@item a
|
||||
@item add, a
|
||||
Select overlap-add method. Even not interpolated samples are slightly
|
||||
changed with this method.
|
||||
|
||||
@item s
|
||||
@item save, s
|
||||
Select overlap-save method. Not interpolated samples remain unchanged.

||||

quality of interpolated samples using neighbour good samples.
|

|

@item t
|

@item threshold, t
|

Set threshold value. Allowed range is from @code{1} to @code{100}.

Default value is @code{10}. Higher values make clip detection less aggressive.
|

@item n
|

@item hsize, n
|

Set size of histogram used to detect clips. Allowed range is from @code{100} to @code{9999}.

Default value is @code{1000}. Higher values make clip detection less aggressive.
