Claim:
1. A system that enhances spatialization, comprising: a receiver that processes incoming signals received from a plurality 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 derives from the received incoming signals spatial information comprising locations of each of one or more sound sources relative to the plurality 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 set of fading weights used for mixing the received incoming signals into each channel of a multichannel output signal to emulate at a receiving location, spatial information representing locations of each of the sound sources relative to the plurality of input devices.
