Title: Innovations of Heinz Gerhäuser

Introduction

Heinz Gerhäuser is a notable inventor based in Waischenfeld, Germany. He has made significant contributions to the field of audio signal processing, holding a total of 10 patents. His work focuses on methods and devices that enhance the detection and coding of audio signals.

Latest Patents

One of his latest patents is a method and device for detecting a transient in a discrete-time audio signal. This method operates entirely in the time domain and involves segmenting the audio signal into consecutive segments of equal length. The current segment's filtered audio signal is then compared to the energy of the filtered signal from a preceding segment to determine the presence of a transient. Another significant patent is a method for signaling noise substitution during audio signal coding. This method transforms the time-domain audio signal into the frequency domain to obtain spectral values. It groups these spectral values and allocates codebook numbers based on whether the group is noisy or not, allowing for efficient redundancy coding.
