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).
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.
