AIR Reverb (RTAS)

Different physical environments have different early reflection signatures that our ears and brain

use to localize sound. These reflections affect our perception of the size of a space as well as

where an audio source sits within it. You can use the Reverb effect to apply Reverb to the audio

signal, creating a sense of room or space.

The following table lists the AIR Reverb plug-in parameters:

Phaser Provides control over the effect’s center frequency and number of phaser stages (or poles).

• Center — Lets you change the frequency center (100 Hz to 10.0 kHz) for the phaser poles.

• Poles — Lets you select the number of phaser poles (stages): 2, 4, 6, or 8. The number of

poles changes the character of the sound. The greater the number of poles, the thicker and

more sweeping the sound.

LFO Provides control over the waveform and stereo offset of the LFO.

• Wave — Lets you interpolate between a triangle wave and a sine wave for modulating the

phaser.

• L/R Phase — Lets you adjust the relative phase of the LFO modulation applied to the left

and right channels.

EQ Provides tonal control over the phase signal. The Low Cut control lets you adjust the frequency

of the Low Cut Filter in the phaser’s feedback loop. This can be useful for taming low frequency

“thumping” at high feedback settings.

Feedback Feeds the output signal of phaser back into the input, creating a resonant or singing tone in the

phaser when set to its maximum.

Mix Lets you balance the amount of dry signal with the amount of wet (effected) signal. At 50%, the

output includes equal amounts of dry and wet signal. At 0%, the output is all dry and at 100% it

is all wet.

Parameter Description

Pre-Delay Determines the amount of time that elapses between the original audio event and the onset of

reverberation. Under natural conditions, the amount of pre-delay depends on the size and

construction of the acoustic space, and the relative position of the sound source and the listener.

Pre-Delay attempts to duplicate this phenomenon, and you can use it to create a sense of

distance and volume within an acoustic space. Long Pre-Delay settings place the reverberant

field behind rather than on top of the original audio signal.

Room Size Changes the apparent size of the space.
