AudioEffectLimiter

Deprecated: Use AudioEffectHardLimiter instead.

Inherits: AudioEffect < Resource < RefCounted < Object

Adds a soft-clip limiter audio effect to an Audio bus.

Description

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 = -0.1 🔗

  • void set_ceiling_db(value: float)

  • float get_ceiling_db()

The waveform's maximum allowed value, in decibels. Value can range from -20 to -0.1.

float soft_clip_db = 2.0 🔗

  • void set_soft_clip_db(value: float)

  • float get_soft_clip_db()

Applies a gain to the limited waves, in decibels. Value can range from 0 to 6.

float soft_clip_ratio = 10.0 🔗

  • void set_soft_clip_ratio(value: float)

  • float get_soft_clip_ratio()

float threshold_db = 0.0 🔗

  • void set_threshold_db(value: float)

  • float get_threshold_db()

Threshold from which the limiter begins to be active, in decibels. Value can range from -30 to 0.
