FIELD: physics, acoustics.
SUBSTANCE: invention relates to means of encoding audio signals and related spatial information in a format which is independent of the playback scheme. A first set of audio signals is assigned to a first group. The first group is encoded as a set of mono audio tracks with associated metadata describing the direction of the signal source of each track relative to the recording position and the initial playback time thereof. A second set of audio signals is assigned to a second group. The second group is encoded as at least one set of ambisonic tracks of a given order and a mixture of orders. Two groups of tracks comprising the first and second sets of audio signals are generated.
EFFECT: providing a technique capable of presenting spatial audio content independent of the exhibition method.
