Abstract (en)

[origin: GB2384149A] A method of audio signal processing for a loudspeaker located close to an ear in use, the method consisting of or including: creating one or more derived signal from an original monophonic input signal, the derived signals being representative of the original signal being scattered by one or more bodies remote from said ear (excluding room boundary reflection or reverberation), combining the derived signal or signals with said input signal to form a combined signal, and feeding the combined signal to said loudspeaker, thereby providing cues for enabling the listener to perceive the source of the sound of the original monophonic input signal to be located remote from said ear.
