A description of the accepted parameters follows.
@table @option
@item nr
@item noise_reduction, nr
Set the noise reduction in dB, allowed range is 0.01 to 97.
Default value is 12 dB.
@item nf
@item noise_floor, nf
Set the noise floor in dB, allowed range is -80 to -20.
Default value is -50 dB.
@item nt
@item noise_type, nt
Set the noise type.
It accepts the following values:
@table @option
@item w
@item white, w
Select white noise.
@item v
@item vinyl, v
Select vinyl noise.
@item s
@item shellac, s
Select shellac noise.
@item c
@item custom, c
Select custom noise, defined in @code{bn} option.
Default value is white noise.
@end table
@item bn
@item band_noise, bn
Set custom band noise for every one of 15 bands.
Bands are separated by ' ' or '|'.
@item rf
@item residual_floor, rf
Set the residual floor in dB, allowed range is -80 to -20.
Default value is -38 dB.
@item tn
@item track_noise, tn
Enable noise tracking. By default is disabled.
With this enabled, noise floor is automatically adjusted.
@item tr
@item track_residual, tr
Enable residual tracking. By default is disabled.
@item om
@item output_mode, om
Set the output mode.
It accepts the following values:
@table @option
@item i
@item input, i
Pass input unchanged.
@item o
@item output, o
Pass noise filtered out.
@item n
@item noise, n
Pass only noise.
Default value is @var{o}.
Default value is @var{output}.
@end table
