ab Decoder Suite by Audio Brewers is a comprehensive collection of plugins designed to process and decode Ambisonics signals for a variety of speaker setups. It supports all First Order Ambisonics (1OA) audio files, including Ambix B-Format, and integrates seamlessly with Audio Brewers libraries. This suite aims to provide precise spatial manipulation and decoding, making it suitable for immersive audio formats such as Surround and Atmos.

The suite features specialized tools that enhance spatial audio control. The visualizer plugin offers clear insights into how sound moves within the spatial field without altering the signal. ab Rotator delivers authentic 3D panning by allowing movement of sound in all directions, including left-right, front-back, and vertical planes, eliminating the limitations of traditional panning methods. ab Dominance adjusts the directional weight of a signal, acting similarly to hard-panning within the Ambisonics environment. Another plugin combines rotation and dominance controls for efficient and precise spatial transformations before decoding.

At the core of the suite is a powerful decoder that automatically adapts to a wide range of speaker arrays, from stereo setups to complex 7.1.4 Atmos configurations. Users can manually customize speaker placement and elevation to fit their specific environment. A lighter version, ab Decoder Light, is also available for quick decoding to various stereo patterns and includes essential features like the rotator, visualizer, and speaker placement controls. Additionally, the suite incorporates a smart troubleshooting algorithm that checks the signal chain, ensuring proper setup and optimal performance.
