The invention relates to a method for generating audio signals, from an input audio signal, to be delivered to a sound reproduction system comprising a first set of loud-speakers at a reference height, and a second set of loud-speakers at a higher height than the reference height, that are vertically more directive than the loud-speakers of the first set. Said method comprises: the identification of a position of at least one sound object of the input audio signal; the generation of first audio signals for feeding the first set, by applying, to the input audio signal, at least one delay and/or a gain and a sound spatialisation technique taking into account the identified position and a position of the loud-speakers of the first set; and the generation of second audio signals for feeding the second set, by applying, to the input audio signal, at least one delay and/or a gain and a sound spatialisation technique taking into account the identified position and a position of the loud-speakers of the second set; at least one sound spatialisation technique being a holophonic technique and the delays and/or gains being selected in such a way that the combination of the first signals restituted by the first set and the second signals restituted by the second set verifies a defined sound restitution effect at at least one reference spatial position. |
