The method further comprises determining, for each loudspeaker based on the THD and the SPL data, a loudspeaker performance profile forming a plurality of loudspeaker performance profiles; and providing the plurality of loudspeaker performance profiles for an adaptation of a sound field generated by the acoustic system.

Abstract: A computer-implemented method for determining audio signal processing parameters for a multi-channel audio system including a plurality of speakers is disclosed. The method involves obtaining at least one first audio response at a first listening position and at least one second audio response at a second listening position, where each audio response corresponds to a respective channel audio signal output by a respective speaker over a predetermined frequency range. The audio signal processing parameters are determined based on a similarity metric calculated between the first and second audio responses over at least a part of the predetermined frequency range. The determined audio signal processing parameters are then provided for further processing of at least one of the channel audio signals, enabling optimization of the audio system's performance across multiple listening positions.

Abstract: The application relates to a method carried out at an audio decoder, wherein a bitstream of compressed audio data including metadata is received by the audio decoder. In the metadata, at least one audio parameter is determined which influences a perception of an audio signal which is generated based on the bitstream and played out by a plurality of loudspeakers. The at least one audio parameter is amended in order to generate an amended bitstream, wherein an amended audio signal generated based on the amended bitstream leads to an amended perception compared to perception when the audio signal is played out by the loudspeakers based on the unamended bitstream.
