Riviera: Hyper-Room Reverb

Riviera: Hyper-Room Reverb is a free reverb VST, VST3, Audio Unit plugin developed by NuSpace Audio. Compatible OS(s): Windows 64b, macOS.

Riviera is a free 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 computations in these spaces are 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).

Features:

  • Voom designer: Adjustable number of dimensions, size, listener offset from sound-source origin, and material reflection dB loss.

  • Time controls: Adjust pre-delay, IR onset/reverser, geometry scale/density sampling, and dimensional attenuation.

  • Frequency controls: Low and high frequency dampening, low-cut linear phase filter.

  • Stereo controls: Pan, Haas, phase, mix (wet/dry), mid/side (mono to difference), and gain.

  • Graphical user interface: Real-time displays to IR and spectrogram.

  • High performance: Low-latency & low CPU usage convolution algorithm, variable max FFT block size, multi-threading support for computing IRs in the background.

Specifications:

  • VST2: Windows 7+, 32/64-bit, Mac OS X 10.7+.
  • VST3, Windows 7+, 32/64-bit.
  • AudioUnit, Mac OS X 10.7+.
  • Minimum SSE2 supported processor with improvements if AVX enabled.
