O7A Reverb
The O7A Reverb plugin library is similar to the O3A Reverb library. It adds synthetic reverberation to seventh order ambisonic (O7A) streams.
This plugin library is intended to work alongside the O7A Core.
The O7A plugins are similar to the O3A plugins, except for the ambisonic "order" in use. The O3A plugins use third order and 16 audio channels to capture a scene, which already gives high spatial precision. The O7A plugins use seventh order and 64 audio channels, which gives much higher spatial precision but is generally only recommended for research applications, or in studios with high-end modern hardware.
These are VST2 or AAX plugins for macOS (10.14 to 13.5) or Windows (10 or 11, 64bit Intel). They can be hosted in some Digital Audio Workstations (DAWs) that can handle tracks with sufficiently high channel counts. Because of the very high channel counts needed for these plugins, this typically means Reaper, Pro Tools Ultimate, or Max/MSP. These plugins use the SN3D higher order ambisonic (HOA) convention, at seventh order, which needs 64 channels. The exact channel counts needed for individual plugins are listed below in the Plugins section.

Algorithmic Reverb
O7A Early Reflection
I/O: 64 in, 64 out
This plugin simulates a single early reflection, but applies it to a complete 3D O7A audio scene.
O7A Reverb - MS3
I/O: 64 in, 64 out
This plugin adds high quality synthetic reverb to a 3D O7A soundfield. It uses the same algorithms as the MS5 reverb but has a simplified control interface.
O7A Reverb - MS5
I/O: 64 in, 64 out
This plugin adds high quality synthetic reverb to a 3D O7A soundfield.
It uses a highly configurable directionally-dependent early reflection model and a rich late reflection model.
O7A Shoebox
I/O: 1 in, 64 out
The O7A Shoebox operates like a panner, but simulates up to 128 dynamic acoustic reflections off the walls of a virtual shoebox-shaped room.
Convolution Reverb
O7A Reverb - Convolution
I/O: 64 in, 64 out
This plugin performs convolution reverb based on a WAV file with up to 64 channels.
O7A Reverb - Shaped Convolution
I/O: 64 in, 64 out
This plugin performs convolution reverb, but with the reverb output controlled by the input's directivity.
Technical Requirements
Please check everything is okay here before purchasing software.Operating System
Supported versions of Microsoft Windows are 10 or 11, 64bit Intel.
Supported versions of Apple macOS are 10.14 to 13.5, 64bit Intel or Apple Silicon.
VST Host
The VST plugins require a VST 2 host with shell plugin support.
These plugins do not work with all VST 2 hosts. One reason for this is that the O7A plugins need large numbers of channels on their input or output busses. Check the individual plugins for the channel counts they need, but all of the O7A plugins need at least 64 channels on each track. Also, at the time of writing VST 2 shell plugins are not supported in Nuendo or Cubase.
AAX Host
The AAX plugins require Pro Tools Ultimate version 2023.6 or later.
PC Hardware
Please check your PC meets the following requirements:
- Intel Core i7 CPU or better, or Apple Silicon.
- 400MB of free disk space.
Permissions
You'll need administrator permissions while installing on Windows. The software probably won't install properly using a "restricted" account.
Internet Connection Required
This software requires an Internet Connection for license activation and verification.
Successful license verification isn't required every time you use the software, but it is needed during installation and needs to succeed once every couple of weeks to keep the license fresh.
The license can be "revoked" to remove it from one machine so it can be moved on to another. You should also do this if you're updating your system in case the machine appears to have changed identity.
