Title: Innovations by Inventor Stefan Varga
Introduction
Stefan Varga is a notable inventor based in Erlangen, Germany. He has made significant contributions to the field of audio processing, holding a total of 4 patents. His work focuses on enhancing audio experiences, particularly in automotive environments.
Latest Patents
One of his latest patents is an "Apparatus and method for processing stereo signals for reproduction in cars to achieve individual three-dimensional sound by frontal loudspeakers." This invention includes a digital processor that features an ambient portion extractor and a spatial effect processing stage. The ambient portion extractor is designed to extract an ambient portion from a multi-channel signal, while the spatial effect processing stage generates a spatial effect signal based on this ambient portion. The digital processor then combines the multi-channel signal with the spatial effect signal to enhance the audio experience.
Another significant patent by Varga is titled "Audio coherence enhancement by controlling time variant weighting factors for decorrelated signals." This apparatus enhances an audio signal by processing it to reduce or eliminate transient and tonal portions. It includes a signal processor, a decorrelator for generating decorrelated signals, and a combiner for weightedly combining these signals. The controller analyzes the audio signal to apply different weighting factors, resulting in a two-channel audio signal with a time-variant degree of decorrelation.
