OctiMax Peak Limiter (multichannel)

mc.omx.peaklim~

Description

omx.peaklim~ is a peak-limiter which allows for the specified control of signal amplitude.

Arguments

None.

Messages

bypass

Arguments

bypass-flag [int]
The word bypass followed by a non-zero number will output the dry unchanged input signal straight out the outlet without any processing; followed by a 0, will output the signal effected by omx.peaklim~.

ingain

Arguments

pre-limiter-gain [float]
The word ingain, followed by a number 0-100, sets the gain (-24 to +24 dB) applied to the signal before limiting.

meterData

When metering is on, the word meterData will cause a list of two values to be sent from the rightmost outlet at a rate specified by the meterRate message. These values describe the gain reduction in dB currently applied to the two input signals.

meterRate

Arguments

data-output-interval [int]
The word meterRate, followed by a number, specifies the interval (in milliseconds) at which the meter data described above will be sent.

meters

Arguments

metering-flag [int]
The word meters, followed by a 1 or 0, turns the metering output on or off. Whe N metering is on, a list of two values will be sent from the rightmost outlet at a rate specified by the meterRate message. These values describe the gain reduction in dB currently applied to the two input signals.

mode

Arguments

response-mode-flag [int]
The word mode, followed by a number, sets the limiter response mode as follows: 0 = punchy, 1 = smooth. Punchy response yields extremely short attack and release times, useful for transparent limiting, or to create loudness. However, if over-used, intermodulation distortion may result. Smooth response uses longer attack and release times. The result is still a fast look-ahead limiter, but with less intermodulation distortion and less punch.

outgain

Arguments

post-limiter-gain [float]
The word outgain, followed by a number (0-100), sets the gain (-24 to +24 dB) applied to the signal after limiting.

saveSettings

The word saveSettings causes all parameter values to be sent out the third outlet.

signal

Audio input, the signal or pair of signals to be compressed.

threshold

Arguments

limiter-threshold [float]
The word threshold, followed by a number (0-100), sets the limiter threshold (-24 to +24 dB below full scale). When the input signal level exceeds this threshold, it will be attenuated as necessary to keep the level below the threshold.

Multichannel Group Messages

Output

list

Out third outlet: parameter values in response to saveSettings message.

Out fourth outlet: meter data. When metering is turned on, lists of values will be output that describe various internal levels. See the description of the meters message.

signal

Out leftmost two outlets: the input signals (if present), with dynamics processing applied.
