AN AUDIO APPARATUS AND METHOD THEREFOR
First Claim
1. An audio apparatus comprising:
- a receiver for receiving an audio signal;
a generator for generating a multichannel signal from the audio signal, the multichannel signal comprising a plurality of signals including at least one primary signal and at least one secondary signal;
a driver for generating a set of drive signals comprising at least one drive signal for a loudspeaker of a set of loudspeakers, the set of drive signals comprising at least a first signal component from the primary signal and a second signal component from the secondary signal;
a position circuit for determining a first position of the loudspeaker;
wherein the driver is arranged to adjust a first level of the primary signal component relative to a second level of the secondary signal component in response to the first position relative to a first reference position, wherein the driver is further arranged to adjust the first level relative to the second level in response to the first position relative to a second reference position.

Abstract
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.

20. A method of operation for an audio system, the method comprising:
-
receiving an audio signal; generating a multichannel signal from the audio signal, the multichannel comprising a plurality of signals including at least one primary signal and at least one secondary signal; generating a set of drive signals comprising at least one drive signal for a loudspeaker of a set of loudspeakers, the set of drive signals comprising at least a first signal component from the primary signal and a second signal component from the secondary signal; determining a first position of the loudspeaker; adjusting a first level of the primary signal component relative to a second level of the secondary signal component in response to the first position relative to a first reference position, and further adjusting the first level relative to the second level in response to the first position relative to a second reference position.
