ACProcessorSuite is a suite of custom plugins for Apple's Quartz Composer, a realtime visual programming environment that comes free with Mac OS X (Developer Tools).
The suite contains:
ACPlotter: An Oscillator-like Line-Renderer, extremely useful to visualize a value, that is changing over time. Just hook it up to an LFO to see what it's doing.
ACStructureTools: Pop & push for structures (= QC Arrays)
ACSignalEnhancer: Various smoothing & scaling algorithms to improve (for example) incoming sensory data. With ACSignalEnhancer it is easily possible to scale values from a range of say 100 .. 255 to e.g. -1 .. +1. Supported modes are: Raw, Average, Smooth, Relative, Drop.
ACAverage: Smoothing values by averaging (like ACSignalEnhancer, but with much less options and easier to use)
ACInputMerger: Logic input selector (forward input A or B)
ACNumberStore: Delay patch (stores & outputs the previous value)
