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. Defines how reflective the imaginary room's walls are. Value can range from 0 to 1. Output percent of original sound. At 0, only modified sound is outputted. Value can range from 0 to 1. 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. Output percent of predelay. Value can range from 0 to 1. Time between the original signal and the early reflections of the reverb signal, in milliseconds. Dimensions of simulated room. Bigger means more echoes. Value can range from 0 to 1. Widens or narrows the stereo image of the reverb tail. 1 means fully widens. Value can range from 0 to 1. Output percent of modified sound. At 0, only original sound is outputted. Value can range from 0 to 1.
