FIELD: physics.
SUBSTANCE: device is proposed for adaptation of the spatial audio signal intended for initial speaker installation, to the speaker installation for playback, which differs from the reference loudspeaker installation. The device comprises a unit of decomposing to the direct sound and the surround sound, which is adapted to decompose the channel signals in the reference loudspeaker installation segment to the components of the direct sound and the surround sound, and to determine the arrival direction of the direct sound components. The unit of presenting the direct sound receives the loudspeaker installation information for the playback and adjusts the direct sound components using the loudspeaker installation information for the playback so that the perceived arrival direction for the direct sound components in the loudspeaker installation for the playback is identical to the arrival direction for the direct sound components.
EFFECT: preserving the audio spatial image, while resetting the audio signal to another loudspeaker installation.
