Abstract (en)
[origin: EP0790753A1] The method involves using a binaural processor (*) with two channels operating for each monophonic sound channel which is to be located. The two channels include filters which are linked to combine signals linearly within the channels. The processor is linked to an orientating device (13) which determines the spatial location of a sound source and is itself connection to a position locating device (3,4,12). Convolution of the signals is performed between the monophonic signal and the user left ear transfer function and the user right ear transfer function. These functions are specific to the particular user. The transfer functions may also include use of a phase interpolation device to determine the appropriate phase for each signal within the two channels.
