6. Preparing Reaper:
The plug-ins were tested with the Reaper DAW (Digital Audio Workstation).
To use the feature of selectable Ambisonics order, Reaper has to inform the plug-ins about the current channel size.
This can be done as follows:
  • Open Reaper after installing the plug-ins
  • Open the plugin browser (click the add button in the FX list of a channel)
  • Open the ICST Ambisonics Plugins Reaper Template; this is perhaps the easiest way to get started.

Note: The v2.3 is not compatible with the v3.0 for older sessions but still available here:
