Mastering Tool Kit parameter functions
Compressor
This effect is used to compress the overall output signal
when the input level exceeds a set value.
Effect On/Off OFF, ON
This setting turns the compressor on or off.
CmpL: Thres -24–0 dB
This parameter sets the volume level at which the low-band
compressor begins to affect the sound.
CmpL: Ratio 1:1.00–1:16.0, 1:INF
This parameter sets the ratio for suppression of the low-band output
when the input level exceeds the Lo threshold.
CmpL: Attack 0–100 ms
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 50–5000 ms
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 -24–0 dB
This parameter sets the volume level at which the middle-band
compressor begins to affect the sound.
CmpM: Ratio 1:1.00–1:16.0, 1:INF
This parameter sets the ratio for suppression of the middle-band
output when the input level exceeds the Middle threshold.
CmpM: Attack 0–100 ms
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 50–5000 ms
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 -24–0 dB
This parameter sets the volume level at which the high-band
compressor begins to affect the sound.
CmpH: Ratio 1:1.00–1:16.0, 1:INF
This parameter sets the ratio for suppression of the high-band output
when the input level exceeds the Hi threshold.
CmpH: Attack 0–100 ms
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 50–5000 ms
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.
Mixer
The mixer is used to adjust the volume of each frequency
band.
Low Level -80–+6 dB
Sets the volume level for the low band after the signal has passed
through the expander and compressor.
Mid Level -80–+6 dB
Sets the volume level for the middle band after the signal has passed
through the expander and compressor.
High Level -80–+6 dB
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.
Effect On/Off OFF, ON
This setting turns the limiter on or off.
Threshold -24–0 dB
Adjust this parameter to match the input signal.
Attack 0–100 ms
Adjusts the time it takes for the limiter to become active once the
input level exceeds the threshold level.
Release 50–5000 ms
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 -80–+6 dB
Sets the volume level of the overall sound after the signal has passed
through the limiter.
Soft Clip Off, On
Soft clipping suppresses the noticeable distortion that may occur
through heavy use of compression and limiting.
Dither OFF, 24–8 BIT
This setting is used to prevent the action of muting sounds from
becoming too noticeable.
