Lexicon 3-2 PCM 80 User Guide The 4-Voice Algorithms The Reverb Shell Each of the 4-Voice algor ithms share a common set of controls and parameters built around one of five stereo reverb effects: Concert Hall, P late, Chamb er, Inverse and Infinite.
3-3 The Algorithms and Their Parameters This a lgorithm em ulates a real concert h all. The reverberation is very clean, and designed to remain behind the d irect sound — add ing amb ience, but lea ving the source unchanged. This effect has a re latively low initial echo density which builds up gra dually over time.
Lexicon 3-4 PCM 80 User Guide The Plate algorithm mim ics t he soun d of m etal plat es, with high initial diffusio n and a re latively bright sound. T his makes them a good choice f or e nhancing any type of percussion.
3-5 The Algorithms and Their Parameters The Chamber algo rithm produces an even, relatively dimensionless reverbera- tion, w ith little change in co lor as the sound decays. The initial diffusion is si milar to the Concert Hall algorithm, but the sen se of sp ace and size is m uch less obvious.
Lexicon 3-6 PCM 80 User Guide Inve rse The Inverse al gorith m allows you to va ry the slope of the initial por tion of the reverb enve lope. The slope can decay, remain level, or rise over a variable time interval. W hen the time i nterval i s up , the reverberation cut s off ab ruptly.
3-7 The Algorithms and Their Parameters Infinite Infinite is a coustically similar to the Chamber algorithm, with the addition of an Infinite parameter . When this parameter is turned o n, the i nput to the reverberat or ramps off. (Note t hat this still allows the Reverb Shell to be utilized.
