Inherits: AudioEffect < Resource < Reference < Object

Adds a reverberation audio effect to an Audio bus.

Simulates the sound of acoustic environments such as rooms, concert halls, caverns, or an open spaces.


Simulates rooms of different sizes. Its parameters can be adjusted to simulate the sound of a specific room.

Property Descriptions

float damping

Default 0.5
Setter set_damping(value)
Getter get_damping()

Defines how reflective the imaginary room's walls are. Value can range from 0 to 1.

float dry

Default 1.0
Setter set_dry(value)
Getter get_dry()

Output percent of original sound. At 0, only modified sound is outputted. Value can range from 0 to 1.

float hipass

Default 0.0
Setter set_hpf(value)
Getter get_hpf()

High-pass filter passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. Value can range from 0 to 1.

float predelay_feedback

Default 0.4
Setter set_predelay_feedback(value)
Getter get_predelay_feedback()

Output percent of predelay. Value can range from 0 to 1.

float predelay_msec

Default 150.0
Setter set_predelay_msec(value)
Getter get_predelay_msec()

Time between the original signal and the early reflections of the reverb signal, in milliseconds.

float room_size

Default 0.8
Setter set_room_size(value)
Getter get_room_size()

Dimensions of simulated room. Bigger means more echoes. Value can range from 0 to 1.

float spread

Default 1.0
Setter set_spread(value)
Getter get_spread()

Widens or narrows the stereo image of the reverb tail. 1 means fully widens. Value can range from 0 to 1.

float wet

Default 0.5
Setter set_wet(value)
Getter get_wet()

Output percent of modified sound. At 0, only original sound is outputted. Value can range from 0 to 1.
