Title: Gerhard J Stoll: Innovator in Digital Audio Technology

Introduction

Gerhard J Stoll is a notable inventor based in Munich, Germany. He has made significant contributions to the field of digital audio technology, holding a total of 3 patents. His work has focused on improving the reproduction accuracy of digital audio signals, particularly in stereo formats.

Latest Patents

One of his latest patents is for a record carrier that has an encoded wide-band digital audio signal recorded thereon. This innovation enhances the reproduction accuracy of digital signals, such as stereo audio signals, by transmitting sample data that have been encoded to form transmission signals. The stereo audio signals are coded into sub(band) signals, allowing for improved processing and recording on a record carrier. Additionally, a mode indicator control signal is recorded to identify whether corresponding sub(band) signals have been processed.

Another significant patent involves a subband coded digital transmission system using composite signals. This invention improves the reproduction accuracy of digital stereo audio signals by transmitting sample data as sub-signals, such as frequency subband signals. In this system, corresponding components of left and right stereo channels are combined, allowing for a single composite signal to be transmitted per subband. An indicator signal is also transmitted to indicate which subbands are combined, enhancing the overall efficiency of the audio transmission.
