Abstract:
1. A system that enhances spatialization comprising: a receiver that processes incoming signals received from an array of input devices that convert sound into electrical signals; a processor that executes a non-transitory computer readable storage medium comprising: computer program code that analyzes the incoming signals to derive spatial information comprising locations of each of one or more sound sources relative to the array of input devices by computing over a range of frequencies an amplitude ratio for a first received signal rotated into phase with a second received signal, and computing from the amplitude ratio over the range of frequencies an average amplitude ratio; and computer program code that derives from the average amplitude ratio a plurality of weighting factors used for mixing the received incoming signals into each channel of a multichannel output signal to emulate, at a location remote from the array of input devices, spatial information representing locations of each of the sound sources relative to the array of input devices.
