Riviera is a free hybrid reverb plugin designed to simulate specular acoustic reflections within complex multidimensional spaces such as strings, plates, rooms, and higher-dimensional shapes. It employs a unique combination of algorithmic and convolution methods to produce rich, immersive reverberations. By optimizing mathematical computations, Riviera achieves efficient processing that makes these advanced reverberation models accessible in real-time audio production environments.

The plugin offers extensive control over its reverb characteristics, allowing users to adjust dimensions, size, listener position, and material reflection loss. It features a variety of time-based settings such as pre-delay and impulse response manipulation, alongside frequency controls for damping and filtering. Stereo imaging options include panning, Haas effect, phase adjustments, and wet/dry mixing, all presented through an intuitive graphical interface with real-time impulse response and spectrogram displays.

Riviera supports multiple plugin formats including VST2, VST3, and AudioUnit, compatible with both Windows and Mac operating systems. It is optimized for low latency and minimal CPU usage, leveraging multi-threading and adaptive FFT block sizes for efficient performance. This makes it a powerful tool for producers and sound designers seeking to explore innovative reverb textures without compromising system resources.
