Cross-platform Waves Nx Head Tracker to OSC bridge for macOS, Windows and Linux. Reimplements the macOS-only NXOSC over a reverse-engineered BLE protocol, exposing yaw/pitch/roll quaternions to any binauraliser or rotator (IEM, SPARTA, Atmoky, APL Virtuoso). The NXOSC you couldn't get on Windows.

Turn an Mbientlab MetaMotion RL into a wireless head tracker for spatial audio. Streams orientation over BLE as OSC for IEM, SPARTA, Atmoky and APL Virtuoso. Optional host-side VQF sensor fusion for magnetometer-free, drift-resistant heading in electromagnetically noisy rooms. MacOS, Windows, Linux.

Complete BLE GATT reverse-engineering of the Jabra Elite 10 Gen 2, mapping its head-tracking service and Google Fast Pair / FMDN authentication. Documents the full protocol, the toolchain used to obtain it, and why the orientation stream is gated by an account-key challenge. A thorough negative-result writeup for anyone attempting host-side access.
