Format Reference
All files in this archive follow the ambiX standard:
- Channel ordering: ACN (Ambisonic Channel Number) — channels sorted by degree and order index
- Normalisation: SN3D (Schmidt Semi-Normalisation)
- Encoding: B-Format, not speaker-decoded audio
To use these files: import into REAPER, set the track to the correct channel count, and route through an ICST AmbiDecoder configured for the matching order. See the Step-by-Step Setup for a walkthrough.
