Audio Brewers releases "ab Decoder Suite" - Set of plugins for manipulating and decoding Ambisonics signals

7th January 2022

Audio Brewers has released ab Decoder Suite, a collection of plugins designed to manipulate, transform and decode Ambisonics signals automatically to multiple speakers arrays. Here's what they say:

The collection of plugins was created with three goals in mind:

  1. They should simply WORK.
  2. They shouldn't have tons of complicated settings or routing requirements.
  3. They should troubleshoot your signal automatically.

ab Decoder Suite also comes with a 'smart troubleshooting' algorithm, which will check the user's signal chain and let them know if something is wrong with it.

The plugins are not only compatible with all Audio Brewers libraries, but also with any 1OA (First Order Ambisonics, or Ambix B-Format) audio file.

The suite contains:

ab Visualiser

This plugin is designed to visualise the signal, a comfortable way to be aware on how the signal revolves in the spatial field, especially if the signal will later be decoded to immersive formats such as Surround or Atmos-compatible formats.


ab Rotator

With 'ab Rotator' the user can transform the signal in the three-dimensional field to have a true translation of how the sound behaves when its moved. Whether if it's left/right, front/back or above/below.


ab Dominance Control

To help the user focus further the sound, 'ab Dominance' is a tool that changes the weight of the signal towards a particular direction.


ab Transformer (Rotator + Dominance)

This plugin includes the 'Rotation' and the 'Dominance' controls in-one, allowing the user to quickly transform the signal without having to be switching plugins.


ab Decoder

This plugin includes all the plugins listed above plus a powerful decoder that will automatically adapt to the most used speaker-arrays our there - all the way from Stereo, to surround and even Atmos beds.

Depending on the user's DAW, 'ab Decoder' might suggest a speaker array, however, the setting can also be manually changed. Additionally, the user can control the placement of the speakers as well as their elevation.


ab Decoder Light (also available for free).

A Lighter version of 'ab Decoder' is also available to quickly decode the Ambisonics signal to different stereo patterns. It contains a rotator, a visualiser and speaker placement controls.
