Brief Description

Adds a soft clip Limiter audio effect to an Audio bus.


float ceiling_db
float soft_clip_db
float soft_clip_ratio
float threshold_db


A limiter is similar to a compressor, but it’s less flexible and designed to disallow sound going over a given dB threshold. Adding one in the Master Bus is always recommended to reduce the effects of clipping.

Soft clipping starts to reduce the peaks a little below the threshold level and progressively increases its effect as the input level increases such that the threshold is never exceeded.

Property Descriptions

float ceiling_db

Setter set_ceiling_db(value)
Getter get_ceiling_db()

The waveform’s maximum allowed value. Value can range from -20 to -0.1. Default value: -0.1dB.

float soft_clip_db

Setter set_soft_clip_db(value)
Getter get_soft_clip_db()

Applies a gain to the limited waves. Value can range from 0 to 6. Default value: 2dB.

float soft_clip_ratio

Setter set_soft_clip_ratio(value)
Getter get_soft_clip_ratio()

float threshold_db

Setter set_threshold_db(value)
Getter get_threshold_db()

Threshold from which the limiter begins to be active. Value can range from -30 to 0. Default value: 0dB.
