Dynamics Parameters
The edit boxes are used to adjust the parameters of each dynamics process. This section gives general definitions of the parameters. See Dynamics Processes for more specific information.
THRESHOLD. The Threshold parameter determines the input level at which dynamics processing begins. For the gate and the expander, processing is activated by signal levels below the threshold. The AGC, the compressor, the limiter, and the peak limiter are triggered by signal levels above the threshold. To adjust the threshold, click and drag the ªTº box at the top of the graph, or click on the ↑ and ↓ buttons of the THRESHOLD edit box.
ATTACK. The Attack parameter controls the amount of time it takes for a gain change to take full effect once a threshold has been crossed. To adjust the attack, click on the ↑ and ↓ buttons of the ATTACK box, or type the desired value in the edit box.
RATIO. The Ratio determines how much the processor will affect the sound. For example, if the compressor is set to a ratio of 2:1, for every 2 dB increase of the input signal above the threshold, the increase of the output signal will be only 1 dB.
To adjust the ratio, click and drag the ªRº box at the right side of the graph, or click on the ↑ and ↓ buttons of the RATIO edit box.
DECAY. The Decay parameter controls the time it takes for the gain to return to unity once the selected process is complete. To adjust the decay, click on the ↑ and ↓ buttons of the DECAY box, or type the desired value in the edit box.
Auxiliary Box. This control functions differently for each dynamics process. See the Dynamics Processes section following for definitions.
