Two Types of Reverb
ADX includes the following two types of reverb.
Reverb
- This reverb type has existed since CRI Audio.
It uses an algorithm called Schroeder's algorithm.
It generates only echo without any early-reflected sound.
This method is best suited in cases where you want to apply a reverb to sounds such as spoken words.
I3DL2 Reverb
- This type of reverb complies with a standard specification called the I3DL2 model. It uses an algorithm called FDN (feedback delay network).
It generates both early-reflected sound and late-reflected sound (echo), and is best suited for representing open space.
There are more parameters than the above types of reverb, but there is a wide variety of presets to choose from.
Additional Notes on Use
Using Reverb
- All ADX reverbs assume that multiple voices are sub-mixed and afterwards processed together in a single batch.
For example, you may set a reverb to be placed on bus 1, and the output of bus 1 to be sent to bus 0.
Then, you can adjust the amount of reverb applied, when sound is played, by changing the amount sent to bus 1 at the bus send level.
Sound Clipping
- Reverb is an effect that adds thickness to the sound source, so you must be careful of clipping in the final output.
You can reduce clipping by adding a compressor on bus 0.
CPU Load
- There is little difference in the CPU load of these two reverb effects.
