Comparison of spatial sound recording techniques with usage of ambisonics and object-based audio [PDF]
International Journal of Electronics and TelecommunicationsIn this article spatial audio recording techniques are compared: scene-based audio and object-based audio. The study involved mixing recordings from a higher-order ambisonic microphone and support microphones, ambisonically encoded on a virtual sphere ...

DiffAU: Diffusion-Based Ambisonics Upscaling
CoRRSpatial audio enhances immersion by reproducing 3D sound fields, with Ambisonics offering a scalable format for this purpose. While first-order Ambisonics (FOA) notably facilitates hardware-efficient acquisition and storage of sound fields as compared to high-order Ambisonics (HOA), its low spatial resolution limits realism, highlighting the need for ...

Sound source localization in virtual reality with ambisonics sound reproduction
To reproduce realistic audio-visual scenarios in the laboratory, ambisonics is often used to reproduce a sound field over loudspeakers and virtual reality (VR) glasses are used to present visual information.

Evaluation of ambisonics decoding methods with experimental measurements
Ambisonics is a sound reproduction technique based on the decomposition of the sound field using spherical harmonics. The truncation in the number of coefficients used to recreate the sound field leads to reproduction artifacts which depend on the ...
