O3A View VST
The O3A "View" library is designed for work with video, both traditional film and modern formats for Virtual Reality.
Use the "View" applications to show video on screen or in VR, synchronized with your Digital Audio Workstation (DAW). In your DAW, you can monitor with a choice of binaural decoder, with head tracking. You can even control some of our plugins from the video display, both on screen and in VR!
These are higher order ambisonic (HOA) VST plugins for macOS (10.7+) or Windows (Win7+) running on 32bit/64bit Intel. They can be hosted in various Digital Audio Workstations (DAWs). To work with O3A, the DAW needs to handle tracks with at least 16 channels (or even 32 for the 32 channel panner). Right now, this means that Nuendo and Cubase do not work with these plugins. But the list of DAWs that do work is growing. Your options include Reaper, Pyramix and Max/MSP.
The View applications are more demanding than the plugins themselves. View requires Windows 10 64bit, or macOS Sierra (10.12). ViewVR requires an HTC Vive and a Windows 10 64bit machine meeting specs for the Vive. ViewVR will not run on macOS at this time. ViewVR is very new and should be considered experimental!
Please note that as part of our Version Two release, our plugins have changed so they expect ambisonics encoded using SN3D rather than FuMa as used previously. Converters between FuMa and SN3D are available in the free O3A Core plugin library (included).
We use some free software and data in this product. Before purchase, please check the license agreement. Prices include VAT where applicable. By beginning the payment process you agree to be bound by our terms and conditions.
The View Applications
Each View application (View or ViewVR) is controlled by an O3A View Sync plugin.
The connection between the plugin and View application is managed over a local network connection, so the application can run on the same machine, or a different one, even one running a different operating system.
The plugin can be used to set the video to be shown in the View application and manage synchronization. Stereographic video formats are supported, although they will only be rendered stereographically in ViewVR.
In ViewVR, 180 and 360 degree videos are presented as you would expect and traditional formats (4:3, 16:9 and 2.39.1) are shown on a rectangular screen within the VR scene. Moving the Head Mounted Display (HMD) results in head tracking data being sent back to the DAW, and the plugin can rotate the soundfield to match.
In View, the same scene is presented as in ViewVR, but on your normal screen (not in VR) - and with a choice of projection. A camera projection gives much the same view as ViewVR and can be panned around with the mouse - in this case, the camera angle is sent back to the DAW as simulated head tracking data. Another option unwraps the scene onto a rectangular projection that is consistent with our VST panning and visualisation surfaces. Grids are available too to help with orientation and the grids and video warp consistently when the scene projection is changed.
Once connected, a few of our plugins acquire an extra "View" button on the top right. This includes the 32 channel panner in this library and some plugins in other libraries (including the free O3A Core). This allows certain spatial controls (typically panning direction) to be controlled from View or ViewVR, using mouse or Vive controllers respectively. In addition, the O3A Flare plugin (in the free O3A Core) can be used to overlay audio visualisations on top of the video image.
Plugins that support this are:
|O3A Core||O3A Beamer, O3A Flare, O3A Look, O3A Panner, O3A Panner - Classic, O3A Panner - Hemisphere, O3A Panner - Large, O3A Panner - Two Channel, O3A Panner - Eight Channel, O3A Rotation|
|O3A Manipulators||O3A Directional Emphasis, O3A Directional Mask, O3A Move, O3A Panner LS, O3A Panner LS XYZ, O3A Reflection, O3A Zoom, O3A Zoom XYZ|
|O3A Reverb||O3A Shoebox|
|O3A Upmixers||O3A Upmixer - Stereo|
|O3A View||O3A Panner 32|

The VR Monitoring Decoder
The VR Monitoring Decoder is used to decode (or "render") an O3A mix to stereo. It is designed to simulate the final output you will get within a VR experience, providing a number of different decoder styles. The various HRTFs provided by Rapture3D are included, as is YouTube's binaural decoder (as of late 2016).
If you place this decoder after the O3A View Sync plugin above and enable head tracking, this can provide head tracked binaural rendering - synchronized with 360 video - while you pan sounds around in VR!
I/O: 16 in, 2 out
This decoder converts O3A mixes to stereo. It has a number of binaural decoder options so you can check how your mix will sound in VR.
I/O: 32 in, 16 out
This provides 32 channels of panning in one plugin. It comes into its own when controlled from the View applications.
Please check that everything is okay here before purchasing software.
For the VST plugins, supported versions of Microsoft Windows are Windows 7, Windows 8 and Windows 10. Supported versions of Apple macOS are 10.7 or later, Intel only. The plugins are available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on macOS).
For the View application, Microsoft Windows 10 64bit or Apple macOS 10.12 (Sierra) is required.
For the ViewVR application, Microsoft Windows 10 64bit is required, along with an HTC Vive and a computer meeting technical requirements for the HTC Vive. macOS is not currently supported.
These plugins are VST 2 plugins, and require a VST 2 host to operate.
These plugins do not work with all VST 2 hosts. In particular, Cubase or Nuendo currently cannot use them. We hope this will change, but in the meantime you can use other hosts such as Reaper, Pyramix or Max/MSP. The reason for this limitation is that the O3A 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 O3A plugins need at least 16 channels on each track, and a few need more (e.g. the 22.2 decoder).
Please check your PC meets the following requirements:
- Intel Pentium D CPU or better for use of the VST plugins.
- Intel Core i5 CPU or better for use of the View application.
- Intel Core i7 CPU or better for use of the ViewVR application, along with technical requirements for HTC Vive.
- 200MB of free disk space.
- Internal network card.
Internet Connection Required
These plugins require an Internet Connection for license activation and verification. We don't really like this, but we can't think of a better way to discourage piracy! Please don't hack our code, it's taken a lot of effort to get it this far...
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.
You'll need administrator permissions while installing on Windows. The software won't install properly using a "restricted" account.
