DynamicsProcessor

Base class for dynamics processors such as compressor, limiter, expander, and gate. This class is useless on it's own. It should be inherited from and have getNextSample overriden.

class DynamicsProcessor : AudioEffect {

EnvelopeDetector detector;

EnvelopeDetector* linkedDetector;

void linkStereo(DynamicsProcessor stereoProcessor);

Functions

linkStereo void linkStereo(DynamicsProcessor stereoProcessor): Allows this processors envelope to be linked to another processor. This way the two will act as a single unit. Both processors must call this on each other to function properly

Variables

_attTime float _attTime;: Time in milliseconds before compression begins after threshold has been crossed
_inputGain float _inputGain;: Amount of input gain in decibels
_kneeWidth float _kneeWidth;: width of the curve that interpolates between input and output. Unit in decibels
_outputGain float _outputGain;: Amount of output gain in decibels
_ratio float _ratio;: Ratio of compression, higher ratio = more compression
_relTime float _relTime;: Time in milliseconds before the compression releases after the input signal has fallen below the threshold
_threshold float _threshold;: Level in decibels that the input signal must cross before compression begins
detector EnvelopeDetector detector;: Tracks the input level to trigger compression.
linkedDetector EnvelopeDetector* linkedDetector;: Will point to the detector of a processor that is stereo linked
x float[] x;: Holds the points used for interpolation;
y float[] y;: Holds the points used for interpolation;

getNextSample float getNextSample(const float input): Process a sample that is passed to the processor, and return the next sample.
reset void reset(): Should be used to free any delay elements or do any setup before play begins.
setSampleRate void setSampleRate(float sampleRate)
