Patent ID: 10536793

Abstract:
The invention relates to a method for reproducing spatially distributed sounds of a multichannel audio signal comprising: receiving time-dependent input audio signals and performing a time-frequency transform; for each time-frequency tile, determining an active directional vector {right arrow over (Da)} and a reactive directional vector {right arrow over (Dr)} from time-frequency representations of different input channels for said time-frequency tile, determining positions of virtual sound sources (VS1, VS2, VS3) with respect to the reference listening point (O) from the active directional vector {right arrow over (Da)} and the reactive directional vector {right arrow over (Dr)}, and determining frequency signal values to each virtual sound sources (VS1, VS2, VS3), and distributing time-frequency signal values of said virtual sound sources to electroacoustic transducers on the basis of a comparison between the positions of the virtual sound sources in the virtual spatial configuration and the actual positions of said electroacoustic transducers in an actual spatial configuration.
