typedef struct _ModuleClipIndicator { ModuleInstanceDescriptor instance; // Common Audio Weaver module instance structure FLOAT32 threshold; // Threshold in dB above which clipping occurs. FLOAT32 attackTime; // Attack time of the clipping detector. Specifies how quickly the value is allowed to rise. FLOAT32 releaseTime; // Release time of the clipping detector. Specifies how quickly the value is allowed to decay. FLOAT32 thresholdCoeff; // Internal derived parameter which equals undb20(threshold). FLOAT32 attackCoeff; // Internal coefficient that realizes the attack time. FLOAT32 releaseCoeff; // Internal coefficient that realizes the release time.
