NuSpace Audio’s free Riviera Hyper-Room Reverb plugin has been updated to version 1.3.0a, receiving an improved GUI, new stereo functions and maintenance fixes.
Riviera is a hybrid algorithmic-convolution reverb plugin for modelling specular acoustic reflections in N-dimensional orthotopes. e.g. string, plate, room, tesseract, and up (vooms or volume+room for short). Normally, direct computation in these spaces is expensive but some clever maths (see tutorial) reduced the asymptotic costs to the point of practical use (e.g. a Reverb plugin). Parameterizing these spaces and then combining them with some fast time-varying frequency decay resulted in some interesting sounding impulse responses (IRs).
New features for v. 1.3.0 include a new GUI, new controls such as gain, stereo mid-side width, and left/right phase offset, as well as a smoother transition for mix knob. The developers have fixed a possible crash in FL Studio, when notify parameter change is on and automation curves are used while adjusting parameters in GUI.
