Abstract

An audio apparatus generates drive signals for a plurality of loudspeakers (101) and comprises a receiver (103) for receiving an audio signal. A divider (105) divides typically a low frequency part of the audio signal into a plurality of audio subbands thereby providing a subband signal for each audio subband of the audio subbands. An analyzer (109) generates acoustic room response indications for each loudspeaker (101) for at least one subband. The indications may be indicative of a coupling of the individual loudspeaker to any room resonances in the individual subbands. A generator (107) generates the drive signals from the subband signals with the generator (107) being arranged to distribute at least a first subband signal of a first subband to the drive signals in response to the acoustic room response indications for the first subband. The analyzer (109) is being arranged to generate a first acoustic room response indication for a first loudspeaker (101) of the plurality of loudspeakers (101) and the first subband in response to a determination of a coupling of the first loudspeaker to at least one room resonance of an acoustic environment for the first loudspeaker (101). The apparatus may mitigate or reduce audio distortions caused by excitation of room resonances in a room.
