Title: Arthur Wolf: Innovator in Audio Signal Processing
Introduction
Arthur Wolf is a notable inventor based in Neu-Ulm, Germany. He has made significant contributions to the field of audio signal processing, holding a total of 5 patents. His work focuses on enhancing audio quality and reducing computational complexity in signal processing systems.
Latest Patents
One of his latest patents is titled "Temporal interpolation of adjacent spectra." This invention exploits the redundancy of succeeding FFT spectra to compute interpolated temporal supporting points. An analysis filter bank is utilized to convert overlapped sequences of an audio signal, such as that from a loudspeaker, from the time domain to the frequency domain. This process generates a time series of short-time loudspeaker spectra. An interpolator then temporally interpolates this time series, which is subsequently fed to an echo canceller that computes an estimated echo spectrum. A microphone analysis filter bank performs a similar conversion for microphone signals, allowing the estimated echo spectrum to be subtracted from the microphone spectrum. This method enables further signal enhancement and results in an echo-compensated audio microphone signal. The overall goal is to reduce the computational complexity of signal processing systems.
