Ambisonic Toolkit (ATK) for REAPER
Ambisonic Toolkit community
ATK for REAPER is an open-source set of JSFX plug-ins for spatial composition, sound design, and VR/360 audio production in the REAPER DAW, supporting first-order Ambisonics. It provides encoders for mono, stereo, UHJ and microphone-array sources, decoders for stereo, surround, periphonic and binaural output, and a set of soundfield transforms for rotation, mirroring, and direct/diffuse manipulation.
History & Background
Developed by Joseph Anderson (DXARTS, University of Washington) and Trond Lossius (The Norwegian Film School), as a port of the broader Ambisonic Toolkit (ATK) — which also exists as ATK for SuperCollider. The toolkit is framed around the soundfield-kernel paradigm and uses Furse-Malham (FuMa) ordering internally with AmbiX bridges. Licensed under LGPLv3.
