FXAlgs #4-11: Classic ¥ TQ ¥ Diffuse ¥ Omni reverbs
Algorithm Reference-12
TQ Verb and TQ Place:
TQ reverbs are 3-PAU algorithms with early reflections. The late portion consists of an input diffuser, injector,
ambience generator with a lowpass filter, low shelving filter, and LFO moving delays, and predelay.
The early reflection portion combines a combination of delays, diffusers, and feedback. The relative delay lengths
are all fixed but are scalable with the E Dly Scl parameter. Relative diffusion lengths are also fixed, and are scalable
with the E DfLenScl parameter. Diffusion amounts are adjusted with E DiffAmt. The E Build parameter ramps the
gains associated with each delay line in a way that changes the characteristic of the onset of the early reflections.
Negative amounts create a slower onset while positive amounts create a faster onset.
The late reverb and early reflection portions are independently mixed together with the Late Lvl and EarRef Lvl
controls. The wet signal is passed through a final high shelving filter before being mixed with the dry signal.
