MIDI Implementation
Description
These boost and cut each of the High,
Middle, and Low frequency ranges.
At -60 dB, the sound becomes
inaudible. 0 dB is equivalent to the
input level of the sound.
Turns the Anti-Phase function on
and off for the Low frequency ranges.
When turned on, the counter-
channel of stereo sound is inverted
and added to the signal.
Adjusts the level settings for the Low
frequency ranges.
Adjusting this level for certain
frequencies allows you to lend
emphasis to specific parts. (This is
effective only for stereo source.)
Settings of the Anti-Phase function
for the Middle frequency ranges
The parameters are the same as for
the Low frequency ranges.
Turns Low Booster on/off.
This emphasizes the bottom to create
a heavy bass sound.
Increasing this value gives you a
heavier low end.
Depending on the Isolator and filter
settings this effect may be hard to
distinguish.
Output Level
Description
Center frequency at which the lower
range will be boosted
Amount by which the lower range
will be boosted
Width of the lower range that will be
boosted
Gain of the low frequency range
Gain of the high frequency range
