Title: Rudolf Geppert: Innovator in Audio Signal Processing
Introduction
Rudolf Geppert is a notable inventor based in Hamburg, Germany. He has made significant contributions to the field of audio signal processing, holding a total of 3 patents. His work focuses on enhancing the performance and accuracy of speech recognition and speaker identification systems.
Latest Patents
One of Geppert's latest patents is a method and arrangement for controlling the gain of an amplifier. This invention is crucial for processing signals applied to audio signal processing devices, such as speech signals received via a microphone in speaker-identification or speech recognition systems. The method involves setting an initial gain value before processing begins and continuously checking the amplified signal's amplitude range to prevent overloading. The optimum gain setting is determined from a histogram of frequencies, allowing for improved performance when the system is used by the same speaker multiple times.
Another significant patent addresses measuring the mis-match between test and reference signals. This process involves sampling both signals at regular intervals and storing them in memories. By calculating the differences between pairs of samples, Geppert's method provides an optimum cumulative distance value, which is essential for accurately matching signals in various applications.
