A method of audio signal processing for loudspeaker (1) located close to an ear (2), the method consisting of or including creating a reverberant signal from an original monophonic signal, modifying the spectral characteristics of the original signal using a first pinna transfer function, modifying the spectral characteristics of the reverberant signal using a further pinna transfer function, combining the modified reverberant signal and the modified original 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 audio signal to be located remote from said ear. The method is particularly advantageous for use in communications apparatus such as telephones or radio transceivers. |
