ambisonics

Containerised HOA 360° livestream stack: Higher-Order Ambisonics (16ch, 3OA) + 4K/8K 360° video over MPEG-DASH. RTMP in, VP9+Opus WebM out, binaural rendering in the browser via a modernised HOAST360 player. Deploys on AMD64 and ARM64.

Supplementary materials (data + R analysis) for a perceptual comparison of 6DoF audio rendering algorithms for classical music in VR - 27 participants, localization accuracy + MUSHRA-like quality ratings, Gamma GLMM, LMM, auto-generated LaTeX statistics.

Reproducible Python pipeline for the AES 160 Convention paper "Zylia ZM-1 vs. Harpex Spcmic: A Case Study of Higher-Order Ambisonic Recording Performance" (Express Paper #51, Copenhagen 2026). Reads B-format WAV files, computes spectral, loudness, spatial-energy, and directional metrics, and emits LaTeX \newcommand macros for the manuscript.

Supplementary materials (data + R analysis) for a perceptual study of the ventriloquist effect in 6DoF VR with Higher-Order Ambisonics - 31 participants, 744 trials, mixed-effects models.

Supplementary materials (data + R analysis) for an objective evaluation of immersive audio formats using BAM-Q and BINAQUAL binaural quality models - 11 formats, 15 metrics, algorithmic metric selection, Higher-Order Ambisonics reference.

This Python script generates an energy visualization video from an Ambisonic (ACN/SN3D) WAV file using precomputed k-NN inverse-distance weighting (IDW) onto a regular 2D grid, multiprocessing for per-frame computation, and direct ffmpeg streaming for efficient encoding.

This script visualizes ambisonic energy as the so-called "Magical Trail Shader", processed with the IEM EnergyVisualizer onto p5.js canvas via OSC messages.

This script visualizes ambisonic energy as the so-called "Frozen Bush", processed with the IEM EnergyVisualizer onto p5.js canvas via OSC messages.

Loudspeaker layout presets for IEM MultiEncoder - Dolby Atmos, Auro-3D, ITU-R, MPEG-H, t-designs, Lebedev grids and more.

This script allows for logging OSC messages from IEM EnergyVisualizer into a CSV file.
