Mastering Tool Kit Parameters
Algorithm
The Mastering Tool Kit’s algorithms are composed from the following e ects.
Algorithm Explanation
Input
This divides the original sound into three frequency ranges:
low, mid, and high.
3BANDCOMP
(Compressor)
This compresses the overall output signal when the input
volume level exceeds a set value.
Mixer Adjusts the volume of each frequency band.
Limiter This suppresses high-level signals to prevent distortion.
Output This makes settings that a ect the overall output.
INPUT
Parameter Value Explanation
Gain -24–+12dB
Sets the overall volume level before the
signal passes through the compressor.
Delay Time 0–10ms
This sets the amount of time by which the
source input sound is delayed.
SplitL 20–800 Hz
This sets the frequency (in the lower range)
at which the source sound is split into
three separate ranges.
SplitH 1.6–16.0 kHz
This sets the frequency (in the upper
range) at which the source sound is split
into three separate ranges.
3BAND COMP
Parameter Value Explanation
On/O OFF, ON
This parameter turns the compressor e ect
on/o .
Lo Threshold -24–0dB
This sets the volume level at which the
lower-range compressor goes into e ect.
Lo Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of suppression of the
lower-range output when the input level
exceeds the Lo threshold level.
Lo Attack 0–100ms
This sets the time it takes for the lower-
range compressor to go into e ect once
the input level exceeds the Lo threshold
level.
Lo Release 50–5000ms
This sets the time it takes for the lower-
range compressor e ect to stop once the
input level falls below the Lo threshold
level.
Mid Threshold -24–0dB
This sets the volume level at which the
midrange compressor goes into e ect.
Mid Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of suppression of the
midrange output when the input level
exceeds the Middle threshold level.
Mid Attack 0–100ms
This sets the time it takes for the midrange
compressor to go into e ect once the input
level exceeds the Middle threshold level.
Mid Release 50–5000ms
This sets the time it takes for the midrange
compressor e ect to stop once the input
level falls below the Middle threshold level.
Hi Threshold -24–0dB
This sets the volume level at which the
upper-range compressor goes into e ect.
Hi Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of suppression of the
upper-range output when the input level
exceeds the Hi threshold level.
Hi Attack 0–100ms
This sets the time it takes for the upper-
range compressor to go into e ect once
the input level exceeds the Hi threshold
level.
Parameter Value Explanation
Hi Release 50–5000ms
This sets the time it takes for the upper-
range compressor e ect to stop once the
input level falls below the Hi threshold
level.
MEMO
With the compressor, the level is automatically adjusted to the optimum
setting according to the Threshold and Ratio settings. In addition, since
lengthening the Attack setting may result in distortion, a margin of -6 dB is
provided. Adjust the Mixer level as needed.
MIXER
Parameter Value Explanation
Lo Level -80–+6dB
Sets the volume level of the lower range
after the signal passes through the
compressor.
Mid Level -80–+6dB
Sets the volume level of the midrange after
the signal passes through the compressor.
Hi Level -80–+6dB
Sets the volume level of the upper range
after the signal passes through the
compressor.
LIMITER
Parameter Value Explanation
On/O OFF, ON Sets the limiter to ON or OFF.
Threshold -24–0dB
Adjust this parameter to match the signal.
Limiting will be applied to input levels in
excess of this level.
Attack 0–100ms
This sets the time it takes for the limiter to
go into e ect once the input level exceeds
the threshold level.
Release 50–5000ms
Adjusts the time until when the limiter will
turn o after the input level falls below the
threshold level.
OUTPUT
Parameter Value Explanation
Level -80–+6dB
Sets the volume level of the overall sound
after the signal passes through the limiter.
