Patent ID: 7505601

Claim:
A device for replicating spatial location of audio signals propagated from a distant sound source to a listener's left and right ears within a centrally switched multi-talker communication system comprising: a plurality of input signals; means for splitting each of said input signals into a plurality of duplicate signals; a plurality of digital filters replicating a ratio of head-related transfer functions of the contralateral and ipsilateral ears for a particular spatial source location in a horizontal plane; a central switching system for receiving output of said plurality of digital filters and processing as a plurality of different channels; a left ear user control panel at the location of the user; a right ear user control panel at the location of the user; said right and left ear user control panels allowing selectibility from particular audio locations determined optimal for the presentation of speech in particular multitalker listening scenarios; and an audio display device for delivering output of said right and left ear user control panels to an operator whereby a user may appropriately select component audio signals presented to each ear and thereby place each input audio signal at a selected location.
