Smoothing out variances in volume (COMP)

 

Parameter

Value

Explanation

TYPE

CHCP-4K,

OPTCP-2A,

FETCP-76

This selects the compressor type.

CHCP-4K: This models a compressor with a built-in expander, such as those found on professional-grade mixers.

OPTCP-2A: This models a vintage optical compressor that uses a vacuum tube.

FETCP-76: This models a classic studio-use FET compressor.

CHCP-4K parameters

Parameter

Value

Explanation

THRES

-60–0 [dB]

Adjusts the base level at which compression starts.

RATIO

0.00–1.00

Adjusts the compression ratio.

The effect works as a limiter when the value is set to 1.00.

FAST ATK

Off, On

When this is on, the compressor switches to fast mode, in which 20 dB of compression is applied within 3 msec.

RELEASE

0–4000 [msec]

Adjusts the time after the input signal volume falls below the threshold until compression stops.

EXPANDER

Off, On

Switches the expander on/off.

EXP THRES

-60–0 [dB]

Sets the threshold (minimum level) with which noise suppression is applied.

EXP RANGE

0.00–1.00

Adjusts the degree to which the expander/gate effect is applied.

When this is set to 0.00, the effect is disabled; and when this is set to 1.00, a maximum of 50 dB noise is suppressed.

EXP RELS

0–4000 [msec]

Sets the speed at which the expander effect is intensified after the signal level falls below the threshold.

OPTCP-2A parameters

Parameter

Value

Explanation

PEAK REDU

0–100

Adjusts the base level at which compression starts.

GAIN

0–100

Adjusts the output level.

HF

0–100

Adjusts the compression sensitivity to high-frequency signals.

FETCP-76 parameters

Parameter

Value

Explanation

IN LEVEL

-Inf, -60–0 [dB]

Adjusts the input volume.

OUT LEVEL

-Inf, -60–0 [dB]

Adjusts the output volume.

ATTACK

0.0–7.0

Sets the time it takes for compression to start once the audio input crosses the threshold.

A value of 0.0 is the longest time it takes for compression to be applied.

RELEASE

0.0–7.0

Adjusts the time after the input signal volume falls below the threshold until compression stops.

A value of 0.0 is the longest time it takes for compression to stop.

RATIO

4:1, 8:1, 12:1, 20:1, ALL

Adjusts the compression ratio.

When this is set to “ALL”, the effect behaves as if all options are selected.
