Title: **Andreas Hölzer: Innovator in Multi-Channel Audio Technology**

Introduction

Andreas Hölzer, based in Erlangen, Germany, is a prominent inventor with a focus on advancements in multi-channel audio technology. With a total of four patents to his name, his work has significantly contributed to efficient audio coding and decoding methods.

Latest Patents

One of Hölzer's latest patents is centered on "Compatible Multi-Channel Coding/Decoding." This innovation pertains to the processing of multi-channel audio signals that utilize at least three original channels. The invention provides a first downmix channel and a second downmix channel derived from these original channels. For a selected original channel, channel side information is calculated to enable a downmix channel or a combined downmix channel. By weighting this downmix channel with the relevant channel side information, it approximates the selected original channel effectively. The output data, composed of the channel side information and the two downmix channels, is transmitted to a decoder. This decoder can either decode just the first and second downmix channels for low-level decoding or deliver a complete multi-channel audio signal based on the downmix channels for higher-level decoding. The innovation stands out for its efficiency and high-quality output, especially suitable for stereo players and enhanced multi-channel audio systems.
