The Algorithms and Effects
01 Isolator & Filter

Isolatr (3-band isolator)

This effect separates the input sound into three
frequency bands, High, Mid, and Low, and cuts or
extracts them.
1. Level Low, Level Mid, Level High
Value: -60 dB–+4 dB
These cut (or increase) each frequency band. At -60
dB, the sound becomes inaudible. 0 dB is equivalent
to the input level of the sound.
2. AntiPhase Low MixSw, AntiPhase Mid MixSw
Value: Off, On
3. AntiPhase Low Level, AntiPhase Mid Level
Value: 0–100
This turns the Anti-Phase function on and off and sets
the level settings for the low and mid frequency
ranges. When turned on, the counter-channel of
stereo sound is inverted and added to the signal. The
level setting allows you to achieve the effect of
extracting only a particular part. (This is effective
only for stereo source.)
In this algorithm, the functions of the machines that
make up the basics for remix artists and pro DJs
have been minutely analyzed and reproduced.
Whereas with ordinary equalizers, some sound is
still audible even when the gain is turned all the
way down, the Isolator completely cuts off the
sound. By turning this on and off and changing each
level in realtime, you can get the effect of having the
sound of particular parts appear and disappear.

Filter

These filters allow you to modify the frequency
response of the input sound widely and give sound a
style.
1. Type
Sets the type of filter used.
Value Explanation
LPF (Low Passes frequencies below the
pass filter) cutoff frequency.
BPF (Band Passes frequencies near the cut-
pass filter) off frequency.
HPF (High Passes frequencies above the cut-
pass filter) off frequency.
BEF (Band
Passes frequencies other than
eliminate
those near the cutoff frequency.

2. Curve (oct)
Value: -12 dB, -24 dB
Sets the filter's attenuation slope (-24 dB per one
octave: steep; -12 dB per one octave: shallow).
3. Freq (Cutoff Frequency)
Value: 0–100
Sets the filter's cutoff frequency. Set this closer to
zero, the cutoff frequency becomes lower; set closer to
100, the cutoff frequency becomes higher.
