The Algorithms and Their Parameters
The Chamber algorithm produces an even, relatively dimensionless reverbera-
tion, with little change in color as the sound decays. The initial diffusion is similar
to the Concert Hall algorithm, but the sense of space and size is much less
obvious. This characteristic, along with the low color in the decay tail makes
Chamber useful on a wide range of material. It is especially useful on spoken
voice, giving a noticeable increase in loudness with very low color. Chamber
