Riviera – Free Algorithmic-Convolution Reverb

Welcome NuSpace Audio,  a new company that debuted this year with its first, clever plugin.
Riviera is a hybrid algorithmic-convolution reverb plugin for modeling 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 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).


  • Low-latency, low CPU usage convolution
  • Multi-threading support for computing IRs in the background
  • Fine-grain controls for parameterizing each voom’s number of dimensions, size, offset from sound-source origin, and material reflection dB loss.
  • Time manipulation controls for delay, stretch, and linearity (RT60 ranges from 1 – 20 seconds!)
  • Fast frequency-dependent time-decay functions
  • Pan/stereo/mix (wet/dry) controls
  • Graphical user interface for displaying IR and spectrogram


  • VST2/VST3, Windows 32 and 64bit
  • Later AU if there’s interest
  • Minimum SSE2 supported processor with improvements if AVX enabled
