If you are deploying a setup for a single computer, you can use a software method to move multiple channels of audio from the DAW running on the same machine as the SPAT Revolution spatialisation environment. This is not normally a trivial task, and many previous solutions have been prone to drop outs and other problems.
In answer to this challenge, FLUX:: has developed a audio pipe technology. Called “Local Audio Path” (LAP) it is available in the two (2) of the three (3) plug-ins available in AU, VST and AAX format.
The SPAT plug-ins offer a straightforward way to integrate the SPAT Revolution spatialisation environment with other digital audio workstation environments - running on the same machine.
In order for the audio software integration to function correctly, the user needs to take into account certain principles of configuration.
!> Sample Rate and buffer size must match in both SPAT and the Plug-in Host
You can configure these settings in the SPAT Revolution Preferences, and matching settings also need to be configured in the host DAW Preferences.
If Sample Rate and buffer size doesn’t match in SPAT Revolution, double-clicking over the “Sync section” at left bottom will automatically adjust them.
Additionally, there is an IO configuration setting inside each plug-in, accessible from the small ‘cogs’ icon. Set the IO Channel Count for each of the plug-ins this way. Each plug-in instance can carry up to 64 channels to and from SPAT. Once you have selected the channel count, Enable the software routing using the Local audio path switch.
If SPAT is running, then a SEND or RETURN IO module will automatically appear in the Environment Setup labelled with the Track Name of the SPAT plug-in, and set to the channel count you have configured in the plug-in. If all is well configuration wise, and a successful local audio stream has been established, the Send and Return modules will have a small green indicator.
On some machines, you need to use the TAB key to register a new Track Name or IP address change in a Spat Plug in.
A few details on some other parameters:
Index - Relates the Plug-in automation to a Virtual Source
Position mode - In Send only, choose the recorded and read coordinates mode.
Local audio path - Enable the inter-application software stream.
Thru - In Send only, choose if you do not want to mute the send audio through the plugin.
OSC Second Output - Set up a second parallel OSC destination.
Report Latency - Activate latency compensation reporting for the DAW.
Override - In Return only, override the DAW input path.
