Title: The Innovations of Andreas Franck
Introduction
Andreas Franck is a notable inventor based in Ilmenau, Germany. He has made significant contributions to the field of audio technology, particularly in the development of advanced filtering techniques. With a total of 10 patents to his name, Franck's work has had a profound impact on the way audio signals are processed and delivered.
Latest Patents
One of his latest patents focuses on FIR filter coefficient calculation for beam-forming filters. This innovation enhances the effectiveness of calculating FIR filter coefficients for transducer arrays, such as arrays of microphones or loudspeakers. The calculation is performed in two stages, first by determining frequency domain filter weights to achieve target frequency responses, and then by calculating the FIR filter coefficients to ensure that the frequency responses approximate the desired outcomes optimally.
Another significant patent involves a device and method for calculating loudspeaker signals for multiple loudspeakers using a delay in the frequency domain. This device transforms audio signals into a spectral domain, allowing for the storage and filtering of short-term spectra. The process culminates in the backtransforming of summed-up short-term spectra to obtain the final loudspeaker signals.
