Mastering Tool Kit parameter functions
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 “delay 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
delay 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 OFF, ON
This parameter turns the equalizer effect on or off.
Input Gain -24–+12 dB
Sets the overall volume before passing through the equalizer.
LowType SHLV, PEAK
Sets the lower-band equalizer type to shelving or peak.
Low Gain -12 –+12 dB
Sets the amount of boost or cut in the lower band.
Low Freq 20 Hz–2.0 kHz
Sets the center frequency for the lower band.
Low Q 0.3–16.0
Sets the steepness of the frequency response curve at the lower
band’s center frequency.
* The Low Q setting is disabled when “SHLV” is selected for the Low Type.
Low-Mid Gain -12–+12 dB
Sets the amount of boost or cut in the lower-middle band.
Low-Mid Freq 20 Hz–8.0 kHz
Sets the center frequency for the lower-middle band.
Low-Mid Q 0.3–16.0
Sets the steepness of the frequency response curve at the lower-
middle band’s center frequency.
Hi-Mid Gain -12–+12 dB
Sets the amount of boost or cut in the upper-middle band.
Hi-Mid Freq 20 Hz–8.0 kHz
Sets the center frequency for the upper-middle band.
Hi-Mid Q 0.3–16.0
Sets the steepness of the frequency response curve at the upper-
middle band’s center frequency.
High Type SHLV, PEAK
Sets the upper-band equalizer type to shelving or peak.
High Gain -12–+12 dB
Sets the amount of boost or cut in the upper band.
High Freq 1.4–20.0 kHz
Sets the center frequency for the upper band.
High Q 0.3–16.0
Sets the frequency response curve steepness at the upper band’s
center frequency.
* The High Q setting is disabled when “SHLV” is selected for the High Type.
Output Level -24–+12 dB
Sets the overall volume level after equalization.
