摘要
An input audio signal is detected to provide a fast time constant control signal which is clamped for immediate response when the input signal drops below a threshold level and filtered to provide a modified control signal with a slow time constant. As the modified control signal level decreases toward the control signal level, a time constant differential control signal decreases and slows the rate of change of the decreasing modified control signal which, as it nears the control signal level, reverts to a slow response. The resulting control signal has an exponential release response which can be applied to an audio dynamics processor. The time constant differential control signal may also be detected to provide an inverted output when it is significantly less than the modified control signal so as to result in the control signal also having an exponential attack response to be applied to the processor.
