Diffuse Verb and Diffuse Place:
Diffuse reverbs are 3-PAU algorithms and are characterized as such because of the initial burst of diffusion inherent
in the onset of the reverb. Each of these algorithms consists of an input diffuser; ambience generator with a lowpass
filter, low shelving filter, and LFO moving delays; and predelay.
In the Diffuse reverbs, the diffuser is implemented a little differently. The diffuser is just inside the ambience
generation loop, so changes in diffusion create changes in the reverb decay. The Diffuse reverbs also offer DiffExtent
and Diff Cross parameters. DiffExtent selects one of seven arbitrary gate-time lengths of the initial diffusion burst,
while Diff Cross adjusts the combination of left and right channels that are diffused.
