@section{description}
|

|
|
|
||
|
|
|
||
|
|
Normalizes the input amplitude to the given level. Normalizer will not
|
||
|
|
overshoot like link::Classes/Compander:: will, but it needs to look
|
||
|
|
ahead in the audio. Thus there is a delay equal to twice the value
|
||
|
|
of the
|
||
|
|
@racketblock[dur:: parameter.

level
|

The peak output amplitude level to which to normalize the input.

@section{argument}
|
||
|
|
dur
|
||
|
|
|
||
|
|
The buffer delay time. Shorter times will produce smaller delays
|
||
|
|
and quicker transient response times, but may introduce amplitude
|
||
|
|
modulation artifacts.
