| resources:tools-software:sigmastudio:toolbox:dynamicsprocessors:peakrmscombonogain [25 Jun 2012 17:27] – format adjustment William Jahn | resources:tools-software:sigmastudio:toolbox:dynamicsprocessors:peakrmscombonogain [29 Jan 2018 23:11] (current) – Changed the example schematic that incorrectly only had the AB compare without the ABS. This was wrong. Then I also added the new cores that are supported. David Thibodeau | ||

| - | The following schematic image shows the PeakRMS Combo algorithm being used on a stereo signal. The external detector path is fed with the larger signal between L and R. This ensures that any rise in signal from either channel will ensure that the output level is reduced. Other applications may be more lenient and can use the average signal between L and R to drive the detector path. The schematic below uses the Input, AB in/out Condition, and Output cells.\\ | + | The following schematic image shows the PeakRMS Combo algorithm being used on a stereo signal. The external detector path is fed with the larger signal between L and R. This ensures that any rise in signal from either channel will ensure that the output level is reduced. Other applications may be more lenient and can use the average signal between L and R to drive the detector path. For that method you would simply sum the left and right using a Signal Merger cell. The schematic below uses the Input, AB in/out Condition, and Output cells. Before the signal is compared you must obtain the absolute value of the two signals. If you do not then the AB compare cell will be comparing two signals where one can be a high level negative signal and the other can be a small positive signal so the output would be the small positive signal since it is the greater of the two. So for this to function as intended you must compare the absolute value of the two signals and take the greater of the two. Internally, the compressor sidechain will take the absolute value so this will not change how the sidechain functions. \\ |
