The ICST Ambisonics Plugins (Reaper DAW)

The ICST Ambisonics Plugins encode and decode Ambisonics B-Format and provide spatial audio production tools for REAPER DAW — free and open source.
Developed at ZHdK Zurich, this site brings together plugin documentation, tutorials, and a living practice: international composers work in our studio through artist residencies, and the public is invited to acousmatic listening sessions (Ascolta). All tools are format-agnostic and built on the open B-Format standard.
