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). Now updated for Mac OS X 10.6. Snow Leopard!
The main two plugins are – ACPlotter, an Oscillator-like line renderer, that plots a series of values over time – and ACSignalEnhancer that provides various smoothing and 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.
Surprisingly, this is the first plotter/oscillator function, as I could not find anything similar on various QC sites or forums. Enjoy!
The second most useful plugins in this suite should be ACSignalEnhancer, which tweaks almost any aspect of how one can improve, scale and bend a numeric value.
The suite contains: 1. ACAverage: Smoothing values by averaging 2. ACInputMerger: Logic input selector (forward input A or B) 3. ACNumberStore: Delay patch (stores & outputs the previous value) 4. ACPeak: Peak Detector (experimental!) 5. ACPlotter: Oscillator like Line-Renderer 6. ACSignalEnhancer: Various smooth & scale algorithms 7. ACStructureTools: Pop & push for structures (= QC Arrays)
NEW in v0.6 (Snow Leopard) 8. ACSignal: Replacement for -Signal: Generate signal after x secs or when x changes 9. ACSignalDelay: Delays a value for x seconds
NEW in v0.7 10. ACBitLogic: 4-to-1-bit Encoder (useful for logic table lookup) 11. ACIdleDetector: Sends a signal if a value remained unchanged for x seconds
