The ICST Ambisonics Plugins (Reaper DAW)

Overview_v3.2

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.

ICST AMBIENCODER – OSC TO FX MAPPING

Institute for Computer Music and Sound Technology (ICST) Zurich University of the Arts – ICST AmbiEncoder sends OSC to FX-Plugins-parameter For whom: Level: Advanced | Audience: Technician, Sound engineer. Integrating ICST AmbiEncoder with IEM FdnReverb via OSC This example demonstrates a simple synchronization between ICST AmbiEncoder and IEM Ambisonics plugins, using FdnReverb to apply distance-dependent reverb. The IEM plugins’ OSC interface makes this process straightforward. OSC <–> OSC Communication FdnReverb (by IEM) is a CPU-efficient reverb for B-format. The goal is to increase reverb as the source moves further away in the spatialization.
