Title: Leif Hakan Claesson: Innovator in Telephone Audio Quality
Introduction
Leif Hakan Claesson is a notable inventor based in Berkeley, CA. He has made significant contributions to the field of audio technology, particularly in improving telephone audio quality. With a total of 2 patents, Claesson's work has had a meaningful impact on communication technology.
Latest Patents
Claesson's latest patents include innovative techniques for enhancing telephone audio quality. One patent describes methods and apparatus for use with a near-end telephone, which generates an outgoing signal directed to a far-end telephone. This invention features a first signal processor that dynamically adjusts the outgoing signal level and a second signal processor that adjusts the incoming signal level. Both processors work to control loop gain, thereby inhibiting loop instability.
Another patent focuses on improving audio clarity and intelligibility at reduced bit rates over a digital network. This invention includes a dynamics processor with a non-linear automatic gain control (AGC) that responds to an input audio signal. The AGC adapts to develop a modified gain audio signal, which is then processed through a multiband crossover device. This device generates multiple signals, each with a unique frequency band, enhancing the audibility of the audio signal in real-time.
