Parameters Used in the 960L Algorithms

Parameter

Parameter Description

Name

 

AmbPreD

Ambience PreDelay (Ambience only) controls the time of a predelay that precedes the early

 

reflection (ambience) component of Stereo Ambience. In the same algorithm, RvbDly controls

 

the predelay that precedes the reverberation component.

AmbSize

Ambience Size scales all the delay elements of the early reflection and early energy

 

components of Ambience and Ambient Chamber algorithms. To keep the early reflection

 

energy within the 15ms-50ms window, this control should be set no higher than about 6 or 7.

AmbLvl

Ambience Level sets the overall level of the early reflection and early energy components of

 

Ambience and Ambient Chamber algorithms.

BassMult

Bass Multiply controls the low frequency reverberation time relative to MidRT. If, for

 

example, Bass Multiply is set to 2X and MidRT is set to 2 seconds, the effective low

 

frequency RT is 4 seconds. For natural sounding results, use settings of 1.5X or less. Note

 

that values less than 1.0X produce a low frequency RT that is shorter than MidRT.

BassXOV

Bass Crossover sets the frequency at which the transition between MidRT and Bass

 

Multiply takes place. Except for special effects, there is seldom a need for this parameter to

 

exceed 500 Hz.

Contour

Contour controls the profile of the energy decay in the reverberation tail. At a value of zero,

 

this decay will be smooth and featureless. Large positive and negative values will add

 

noticeable bumpiness of the decay. Use non-zero values with great caution.

CtrRvb

Center Reverb Level controls the reverberation level of the Center output in surround

 

algorithms. This allows the Center Reverb Level to be set relative to both early reflection

 

levels and the Front and Rear Reverb Levels. We recommend that the center reverb level be

 

set about 4.5dB lower than the Front Reverb Level and the Rear Reverb Level. RvbLvl is a

 

master control for CtrRvb, FrRvb and RearRvb.

Definition

Diffus

Definition is found only in the Chamber and Reverse algorithms. It models the irregularity of reflecting surfaces in the space.

In Chamber, turning Definition up makes reflections more discrete, making the reflecting surfaces seem less diffuse. Except for special effects, it is recommended that this be set to zero.

In Reverse, Definition controls density buildup; lower values produce more density.

Diffusion models the effect of irregular wall surfaces in a room by changing echo density. Very low values produce sharp, discrete early reflections. Higher values produce groups of reflections that are smoother but less articulated. Except for special effects, it is recommended that this control be set to a high value.
