AN AUDIO APPARATUS AND METHOD THEREFOR

摘要

An audio apparatus comprises a receiver (201) which receives an audio signal. A generator (203) generates a multi-channel signal including a primary signal and a secondary signal. For example, the multi-channel signal may include a center speech signal and an ambient signal. A driver (205) generates drive signals for a set of loudspeakers (109-15) which for a loudspeaker will include at least a first signal component from the primary 5 signal and a second signal component from the secondary signal. A position circuit (207) determines the position of the loudspeaker (109) and the driver (205) adjusts a level of the primary signal component relative to a level of the secondary signal component in response to the first position relative to a reference position. The approach may allow automated adaptation of the audio rendering to specific loudspeaker configurations and may in particular 10 support optimized rendering for a plurality of listening zones.
