Latest Patents
Gunnarsson's latest patents include a method for HRTF pre-processing for audio applications. This invention provides a system for processing Head-Related Transfer Functions (HRTFs) for multiple directions of sound incidence. The method aims to improve the generation and simulation of ear signals that correspond to a diffuse sound field. It involves applying phase adjustments to each HRTF to reduce Interaural Time Differences (ITD) and adding direction-dependent Interaural Phase Differences (IPD) to enhance the modeling of sound fields.
Another significant patent is an audio decoder designed to convert audio input channels for headphone listening. This technology is configured to receive input signals from at least two audio channels and provides both direct and cross-feed signal paths. The audio decoder applies head shadowing filters and phase shift filters to simulate the effects of loudspeakers placed at various angles relative to the listener. This innovation enhances the listening experience by accurately representing the phase differences that occur between the ears.
