Mastering Tool Kit Parameter Functions
Bass Cut Filter
This is a filter that cuts unwanted low range noise, such as pops.
On/Off OFF, ON
This setting turns the Bass Cut Filter on/off.
Freq 20 Hz–2.0 kHz
This sets the frequency containing popping or other undesirable
lower-range noises that you want to cut.
Enhancer
This adds more liveliness to the sound, putting sounds at the
forefront.
On/Off OFF, ON
This parameter turns the enhancer effect on/off.
Sens 0–100
This sets the amount of Enhancer that is applied.
Freq 1.0–10.0 kHz
Sets the frequency at which the enhancer effect will begin to be
applied.
Mix Lvl -24– +12 dB
Sets the volume of the effect sound.
Input
This divides the original sound into three frequency ranges: low,
mid, and high.
Gain -24– +12 dB
Sets the overall volume level before the signal passes through the
expander/compressor.
Dly Time 0–10 ms
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.
Expander
This expands the dynamic range at a fixed ratio.
On/Off OFF, ON
This setting turns the expander on/off.
Lo Thres -80–0 dB
This sets the volume level at which the lower-range expander goes
into effect.
Lo Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of increase in output of the lower range when the
input level falls below the Lo threshold level.
Lo Attack 0–100 ms
This sets the time it takes for the lower-range expander to go into
effect once the input level falls below the Lo threshold level.
Lo Release 50–5000 ms
This sets the time it takes for the lower-range expander effect to stop
once the input level exceeds the Lo threshold level.
Mid Thres -80–0 dB
This sets the volume level at which the midrange expander goes into
effect.
Mid Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of increase in output of the midrange when the
input level falls below the Middle threshold level.
Mid Attack 0–100 ms
This sets the time it takes for the midrange expander to go into effect
once the input level falls below the Middle threshold level.
Mid Release 50–5000 ms
This sets the time it takes for the midrange expander effect to stop
once the input level exceeds the Middle threshold level.
Hi Thres -80–0 dB
This sets the volume level at which the upper-range expander goes
into effect.
Hi Ratio 1:1.00–1:16.0, 1:INF
This sets the ratio of increase in output of the upper range when the
input level falls below the Hi threshold level.
Hi Attack 0–100 ms
This sets the time it takes for the upper-range expander to go into
effect once the input level falls below the Hi threshold level.
Hi Release 50–5000 ms
This sets the time it takes for the upper-range expander effect to stop
once the input level exceeds the Hi threshold level.
