Description

 

This bundle is the companion REAPER environment for The B-Format as Score:
Composition, Interpretation, and Spatial Form in Ambisonics (Johannes Schütt, 2026),
submitted to the Journal of Artistic Research (JAR) via the Research
Catalogue platform.

It turns a freshly installed REAPER into a configured playground for the
paper's ambisonic experiments: pre-configured ReaScripts, Lua helpers,
JSFX plug-ins (notably Raumpartitur_Analyzer.jsfx), the SpaceScore
integration (Python + Lua + JSON example data), and a starter Project
Template for user experimentation.

What the ZIP contains (tool only): Scripts, Effects (JSFX), Data,
UserPlugins binaries (ReaPack, SWS, Helgobox for Apple Silicon),
configuration files, Templates/SpaceScore/ (Python companion + docs),
ProjectTemplates/Default/ (scaffold), and the install guide as README.md.

What the ZIP does not contain — but is needed per experiment:

  • REAPER.app itself (licensing reasons — install from reaper.fm into the
    bundle folder per README §3.2).
  • The IEM, ICST, and SPARTA plug-in suites (install per README §3.4–3.6).
  • Each experiment session (HeadTracking_Demo, JAR_MultiDecoder, M-series,
    Rethinking Thought study sets, etc.) is published as a separate
    Zenodo record     with its own DOI. Download only the sessions you need.

Target platform: Apple Silicon macOS 13+ (Ventura, Sonoma, Sequoia).
Tested on REAPER v7.69 / IEM v1.15.0 / SPARTA v1.8.2. Windows 10/11 not
tested; see README §4.

License: Bundle documentation, scripts, JSFX, and configuration are
CC BY 4.0. Third-party components retain their own licenses (see README §8).

Reproducibility: This bundle has been verified against README §6
Verify the install. See the accompanying test protocol record for
SHA-256 hashes, test date, and per-check results.
