Title: Innovations in 3D Audio by Stefan Abeling

Introduction

Stefan Abeling, an innovative inventor based in Schwarmstedt, Germany, has made significant contributions to the field of audio technology. With a remarkable portfolio of 9 patents, Abeling specializes in methods and apparatus that enhance audio experiences, particularly in the realm of higher-order ambisonics and 3D sound representation from 2D sources.

Latest Patents

Abeling's latest patents include techniques for higher-order ambisonics decoding that involve the encoding and decoding of HOA signals using Singular Value Decomposition. This process entails forming based on sound source direction values and Ambisonics order ket vectors reflective of spherical harmonics. By conducting a Singular Value Decomposition on the encoder mode matrix and comparing singular values with a threshold value, the final encoder mode matrix rank can be evaluated. This system provides an advanced method for generating an adaptive Ambisonics ket vector, ultimately leading to refined output signals for loudspeakers.

Another noteworthy patent addresses the generation of a 3D sound representation signal from a multi-channel 2D audio input. As a solution to the lack of effective methods for creating 3D audio from existing 2D content, this invention spatially redistributes sound by utilizing a multi-channel 2D audio input and producing an HOA representation alongside channel object signals. Additional signals are strategically placed in 3D space, ensuring a more immersive auditory experience.
