Array-Agnostic Ambisonics Encoding via Diffusion Posterior Sampling
Amit Milstein, Nir Shlezinger, Boaz Rafaely
Spatial audio enhances user immersion by reproducing 3D sound fields, with Ambisonics being a widely adopted representation. While Ambisonics is theoretically independent of the re…

DiffAU: Diffusion-Based Ambisonics Upscaling
Amit Milstein, Nir Shlezinger, Boaz Rafaely
The paper introduces DiffAU, a diffusion‑model‑based method that upscales first‑order Ambisonics recordings to third‑order Ambisonics, improving spatial resolution of 3D audio.
