Brief Description

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

Member Variables

  • float ceiling_db - The waveform’s maximum allowed value. Value can range from -20 to -0.1. Default value: -0.1dB.
  • float soft_clip_db - Applies a gain to the limited waves. Value can range from 0 to 6. Default value: 2dB.
  • float soft_clip_ratio
  • float threshold_db - Threshold from which the limiter begins to be active. Value can range from -30 to 0. Default value: 0dB.


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.
