<p>Audio signal adjustment apparatus including left and right signal channels (4, 6) for connection to respective left and right sound transducers (18, 20), means (8-30) within each channel for adjusting signal parameters for varying the stereophonic effect produced by the transducers, such adjusting means including azimuthal adjustment means (24-30) for adjusting the stereophonic effect in dependence on the azimuthal orientation (υ) of the facing direction (D) of a listener's head (16) in relation to an imaginary plane (22) containing the listener's head and the sound transducers, the azimuthal adjustment means including a filter means (28, 30) with a transfer function adjustable in dependence on a set of stored items of information relating to binaural head-related transfer functions representing predetermined angles of said azimuthal orientation, and user operable means (14, 15) for selecting a desired item for modification of the filter transfer function.</p> |
