Latest Patents

Zölzer's latest patents include a method for analyzing and decomposing stereo audio signals. This method involves extracting panning coefficients that provide direction information about sound sources. By utilizing an approximation that considers one sound source as dominant for each frequency, the method achieves lower computational complexity compared to prior art. The resulting sound quality after re-panning the signal for configurations with more than two loudspeakers is either constant or improved. Additionally, he has developed a method for producing multichannel sound from stereo audio signals. This process includes ascertaining panning coefficients, extracting direct and ambient signals, and converting audio channels into playback signals for multichannel audio systems.
