FDN64Reverb is a powerful reverb plugin featuring a large feedback delay network with a 64 by 64 feedback matrix. This expansive matrix design allows for rich and complex reverberation textures, offering users multiple types of feedback matrices such as orthogonal, circulant orthogonal, and Schroeder reverb, among others. The plugin provides independent control over all internal parameters except for the manually challenging feedback matrix tuning, and includes useful features like matrix input gain rotation and a gate to quickly stop the reverb effect.

Due to the extensive size of its feedback matrix, FDN64Reverb places a significant demand on CPU resources, making it best suited for use with freeze or bounce functions within your digital audio workstation. The plugin is currently experimental on macOS and specifically designed to run on Ubuntu 22.04 for Linux users, with build instructions available for other Linux distributions. Its source code is openly available, encouraging community involvement and development.

FDN64Reverb stands out as a sophisticated tool for producers and sound designers seeking deep control over reverb effects and spatial sound manipulation. Its broad selection of matrix types and parameter controls allow for creating unique reverberation environments, from traditional to highly experimental sounds. Users interested in exploring advanced reverb processing will find this plugin a compelling addition to their audio production toolkit.
