O7A Music
The O7A Music plugin library provides a small collection of creative tools for use with seventh order ambisonic (O7A) streams.
The plugins included are:
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. Not all plugins are supported in AAX.

Effects
O7A Bitcrusher
I/O: 64 in, 64 out
Degrades audio as if it had been passed through a low-resolution digital system.

This plugin applies overdrive distortion to an O7A scene, or a target region in it.
Panner
O7A Shells Split
I/O: 8 in, 128 out
AAX: not supported
VST2: extreme channel count excludes most hosts
This panner places eight sounds in a 3D space that is separated into two shells based on distance.
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.
Due to channel and stem restrictions, not all plugins are supported in AAX. Please see the plugin descriptions for details.
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.
