• Progressive Release: 0 - 100, slowest - fastest (default: 50)
Sets the speed at which the release time is increased faster at very low gain
values. This feature approximates a logarithmic release to help recovery
from dramatic gain reduction more quickly.
Multiband AGC
This section is the heart of the dynamics processing engine. A multiband
AGC (i.e., compressor) that allows for medium ratio (3:1 is default)
adjustment of audio band. Adjustable parameters are:
• Ratio: 1.0:1 to Inf: 1 (default: 3.0:1)
• B1-B5 Inf: 1 Above Thresh: Enabled / Disabled
default:
B1: Enabled
B2: Enabled
B3: Disabled
B4: Disabled
B5: Disabled
AGC automatically increases ratio to Infinity:1 once a signal exceeds the
threshold (set below), allowing for expansion below the threshold and
limiting above the threshold. Useful for bass frequency control.
• Range: 0 dB to 24 dB (default: 24 dB)
Range sets how much gain expansion above unity is able to be performed.
This adjustment is reflected in real time by changing the AGC meter scale.
• Progressive Release: 0 - 100, slowest - fastest (default: 50)
Sets the speed at which the release time is increased faster at very low gain
values. This feature approximates a logarithmic release to help recovery
from dramatic gain reduction more quickly.
• B1 - B5 AGC Attack: 0 - 150, slowest - fastest
default:
B1: 46
B2: 88
B3: 88
B4: 88
B5: 92
Sets how fast an input signal is acted upon once is crosses the set threshold.
