CLASS:: SendPeakRMS
|
|
summary:: Track peak and power of a signal for GUI applications.

|
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.
|
|
|
|
|
|
CLASSMETHODS::
|
|
|
|
private:: new1
|
|
|
|
|
|
method::ar, kr
|
|
|
|
Unlike with other unit generators, the code::ar:: and code::kr:: methods do not
|
|
specify the rate of the computation, but the granularity. When the SendPeakRMS ugen
|
|
is instantiated with code::kr::, the reply rate id quantized to control-rate
|
|
blocks.
|
|
|
|
argument::sig
|
|
|
|
The input signal.
|
|
|
|
argument::replyRate
|
|
|
|
Float or Integer. Specifies the number of replies that are sent to the clients
|
|
per second.
|
|
|
|
argument::peakLag
|
|
|
|
Float or Integer. Lag time, which is applied to the peak values. This option is
|
|
commonly used for GUI VU meters.
|
|
|
|
argument::cmdName
|
|
|
|
Symbol or String. Address pattern for reply message.
|
|
|
|
argument::replyID
|
|
|
|
Integer ID (similar to link::Classes/SendTrig::).
|
|
|
|
INSTANCEMETHODS::
|
|
private:: numOutputs, writeOutputSpecs
|
|
|
|
|
|
EXAMPLES::
|
|
|
|
code::
|
|
(
|
|
{
|
|
SendPeakRMS.kr(Dust.ar(20), 20, 3, "/replyAddress")
|
|
}.play;
|
|
)
|
|
|
|
(
|
|
o = OSCFunc({ |msg|
|
|
"peak: %, rms: %".format(msg[3], msg[4]).postln
|
|
}, '/replyAddress');
|
|
)
|
|
o.free;
