U-he Protoverb 

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

  1. The demo of the Fruity Loops 20 DAW has a Fruity Convolver, Fruity Reverb and Fruity Reverb 2 – this are very powerful reverb plugins, but are not free and portable, you can use them around the DAW and mix-down as a audio file (the demo of the FL doesn’t allow to save project and reopen in the demo version 😉 it is the the most pity thing ever).

    • Hey 🙂 cool but I search for this list only plugins that are free for everyone, no demo versions and compatible for PC & Mac with 64-bit.
      Thanks for your input 😉

    • Hey, thanks for your input. I know but please read the intro of the list: I consider only plugins that are compatible with PC & Mac at the same time and 64-bit. We live in 2018 and prefer free stuff that works on both systems 😉
