Note: While materials are used to control decay rates as a function of fre-
quency, the overall decay rate of the late-field reverberation is controlled from 
the Timing panel (see Figure 162 on page 493). 
To configure the room material and thickness:
1. 
Select a room material from the first (left) pop-up menu. The selected mate-
rial appears in the left side of the Material circle. 
2. Adjust the thickness for the first material with the top horizontal slider:
• A default thickness of +100% yields normal, real-world decays for the ma-
terial. 
• Thicknesses beyond the default (up to +200%) exaggerate how the frequen-
cies are absorbed and reflected. 
• Negative thicknesses invert the response of the material. If the material nor-
mally absorbs high frequencies (causing them to decay quickly) and reflects 
low frequencies (causing them to decay slowly), a negative thickness will in-
stead absorb low frequencies (causing them to decay quickly) and reflect 
high frequencies (causing them to decay slowly). 
• A thickness of 0% yields decay rates that are not affected by the material.
3. Select a material from the second (right) pop-up menu. The selected mate-
rial appears in the right side of the Material circle. Adjust the material thick-
ness with the bottom horizontal slider.
