How the Mastering Tool Kit Parameters Work

This is a compressor effect that controls the volume level for
each frequency range (lower range, midrange, and upper
range) separately in order to even out the differences
between them.
This allows you to achieve the optimal level when mixing
down to MD or DAT, and when using CD-R disks to create
your own original audio CDs.

Effect of the input "detect time"
With regular compressors, once excessive levels are
detected, there is a momentary delay before the signal is
suppressed. This algorithm circumvents this problem by
using the input sound only for detection of the level,
while a predetermined amount of delay is applied to the
sound that is actually processed and output. The input
detect time is the delay time setting used for this
purpose.
Dividing the signal into separate frequency ranges
To divide the sound into separate frequency ranges, set
the Low-Split Point (Split Freq L) and High-Split Point
(Split Freq H).

Equalizer

Effect On/Off
This parameter turns the equalizer effect on/off.
Input Gain
Sets the overall volume before passing through the equalizer.
LowType
Sets the equalizer type (shelving, peaking) for the lower
range.
Low Gain
Sets the amount of boost or cut in the lower range.
Low Freq
Sets the center frequency for the lower range.
Low Q
Sets the steepness of the frequency response curve for the
lower range's center frequency. (*1)
LowMid Gain
Sets the amount of boost or cut in the mid-low range.
LowMid Freq
Sets the center frequency for the mid-low range.
LowMid Q
Sets the steepness of the frequency response curve for the
mid-low range's center frequency.
HighMid Gain
Sets the amount of boost or cut in the upper-low range.
HighMid Freq
Sets the center frequency for the upper-midrange.
HighMid Q
Sets the steepness of the frequency response curve for the
upper-low range's center frequency.
High Type
Sets the equalizer type (shelving, peaking) for the upper
range.
High Gain
Sets the amount of boost or cut in the upper range.
High Freq
Sets the center frequency for the upper range.
