Compressor

This effect is used to compress the overall output signal
when the input level exceeds a set value.
On/Off
This setting turns the compressor on or off.
CmpL: Thres
This parameter sets the volume level at which the low-band
compressor begins to affect the sound.
CmpL: Ratio
This parameter sets the ratio for suppression of the low-band output
when the input level exceeds the Lo threshold.
CmpL: Attack
Sets the time it takes for the low-band compressor to start affecting
the sound once the input level exceeds the Lo threshold.
CmpL: Release
Sets the time it takes for the low-band compressor to stop affecting
the sound once the input level falls below the Lo threshold.
CmpM: Thres
This parameter sets the volume level at which the middle-band
compressor begins to affect the sound.
CmpM: Ratio
This parameter sets the ratio for suppression of the middle-band
output when the input level exceeds the Middle threshold.
CmpM: Attack
Sets the time it takes for the middle-band compressor to start affecting
the sound once the input level exceeds the Middle threshold.
CmpM: Release
Sets the time it takes for the middle-band compressor to stop affecting
the sound once the input level falls below the Middle threshold.
CmpH: Thres
This parameter sets the volume level at which the high-band
compressor begins to affect the sound.
CmpH: Ratio
This parameter sets the ratio for suppression of the high-band output
when the input level exceeds the Hi threshold.
CmpH: Attack
Sets the time it takes for the high-band compressor to start affecting
the sound once the input level exceeds the Hi threshold.
CmpH: Release
Sets the time it takes for the high-band compressor to stop affecting
the sound once the input level falls below the Hi threshold.
With this compressor, the level is automatically adjusted
to the optimum setting in response to the threshold and
ratio settings. In addition, since lengthening the attack
setting may result in distortion, a buffer (or safety
margin) of -6 dB is implemented. Adjust the mixer level
if so required to compensate for this.

Mastering Tool Kit parameter functions

Mixer

The mixer is used to adjust the volume of each frequency
band.
Low Level
Sets the volume level for the low band after the signal has passed
through the expander and compressor.
Mid Level
Sets the volume level for the middle band after the signal has passed
through the expander and compressor.
High Level
Sets the volume level for the upper band after the signal has passed
through the expander and compressor.

Limiter

This effect is used to suppress high-level signals so that
distortion can be prevented.
On/Off
This setting turns the limiter on or off.
Threshold
Adjust this parameter to match the input signal.
Attack
Adjusts the time it takes for the limiter to become active once the
input level exceeds the threshold level.
Release
This adjusts the time it takes for limiting to be removed once the
signal level drops below the threshold.

Output

This component is used to control the overall output.
Level
Sets the volume level of the overall sound after the signal has passed
through the limiter.
Soft Clip
Soft clipping suppresses the noticeable distortion that may occur
through heavy use of compression and limiting.
Dither
This setting is used to prevent the action of muting sounds from
becoming too noticeable.
