@section{description}
|
|
|
|
|
|
The SendPeakRMS unit generator computes peak and power of a signal and sends the
|
|
computed values back to the clients. It does not produce any output.

Unlike with other unit generators, the
|
|
@racketblock[ar:: and ]
|
|
|
|
@racketblock[kr:: methods do not
|
|
specify the rate of the computation, but the granularity. When the SendPeakRMS ugen
|
|
is instantiated with ]
|
|
|
|
@racketblock[kr::, the reply rate id quantized to control-rate
|
|
blocks.

replyRate
|
|
|
|
Float or Integer. Specifies the number of replies that are sent to the clients

per second.

@section{argument}
|
|
peakLag
|
|
|
|
Float or Integer. Lag time, which is applied to the peak values. This option is
