The Sonsig rev-A Black Friday deal from Relab Development takes 80% off, bringing this algorithmic reverb plugin to $29 until Nov 30, 2026.
Sonsig Rev-A is a true-stereo algorithmic reverb that pairs a classic reverb engine with modern filter and modulation controls. The maker describes it as an easy-to-use plugin built to get you a usable reverb fast.
You get 10 reverb sizes, each with its own adjustable decay time. They cover vintage-flavoured spaces as well as clear, natural modern rooms and halls.
The controls are menu-free: Tempo-Lockable PreDelay, Size, Decay, Width and Diffusion. A Freeze function holds the reverb at infinite sustain, which the maker pitches for abstract spatial effects and drones.
Three Output Render Modes change the overall character of the reverb with one switch:
The maker calls the modulation the world's first in-reverb true ensemble chorus. It runs three modulation algorithms at the same time, and the maker says this keeps the tail clean even on the longest decay settings.
Psychoacoustic Spatial Alignment (PSA) is the maker's proprietary algorithm technology behind the sound. According to the maker, the phasing, filtering, diffusion and modulation of every echo fragment in a tail are continuously aligned to a psychoacoustic model.
The maker's claim is a reverb that changes its feel over time, like an instrument, instead of sitting static.
On Mac it needs macOS 10.15 or above, in VST, VST3, AU and AAX (64-bit), and it is M1 native. On Windows it needs Windows 10 or above, in VST, VST3 and AAX (64-bit). Both platforms ask for 2GB of RAM. The plugin is 64-bit only.
