A dynamics processor that compresses in highly definable frequency bands. The graph displays frequencies in Hertz horizontally and gain in decibels vertically. This allows for precise compression specific to defined frequency bands and is useful for taming only one or several parts of a signal.
The default setting of the Multiband Compressor
Each band has dynamics control in the determined frequency ranges of Low, Med, and High and are adjustable by pushing the intersection mark on the graph per band or by typing in a frequency.
Bands 1 – 4: Controls for each band.
— Threshold: Sets the maximum allowable output level. The default is –25dB. The range is from –50 to 0dB.
— Gain: Can add or attenuate up to 12 dB of gain.
— Ratio: Adjusts the compression ratio. This sets the gain reduction ratio (input to output) applied to signals that rise above the threshold level. The default is 1.5.0:1. The range is 1.0:1 to 7:1.
— Limit: Limits the output amount by up to 15 dB. The default is 4.5 dB.
— Attack: Adjusts the attack rate time constant of the sidechain detector. The default is 1.4 mS. The range is 0.1 to 100 mS.
— Hold: Keeps dynamics from being triggered again until a certain amount of time has passed, in mS (milliseconds). Defaults to 0mS. The range is from 0 to 4000 mS.
— Release: Adjusts how quickly the sidechain detector stops applying dynamics when a signal goes back below the threshold. The default is 150 mS. The range is 50 mS to 4.0 S.
