Protoverb is an experimental reverb based on the idea of a “room simulator”. Most algorithmic reverbs try to avoid resonances or model the reflections of sound from a rooms walls. Protoverb does the opposite. It builds up as many room resonances as possible, modeling the body of air in the room. It therefore does not need to modulate or colour the signal.
The result is a very natural sounding reverbration with some interesting features: Long standing frequencies resonate louder, as if the air takes some time to get excited. Multiple instruments don’t mash into a diffuse mud, they stay distinct. If you play a short melody, the room seems to repeat a ghost echo of that melody. Those properties are indeed found in churches and large halls, but they’re rarely found in conventional algorithmic reverbs.

NuSpace Audio Riviera
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 (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).
- 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
