Abstract (en)

[origin: WO2021064311A1] The invention relates to a method for determining a set of corrections (Corr.) to be made to a multichannel sound signal, in which the set of corrections is determined on the basis of an item of information representative of a spatial image of an original multichannel signal (Inf.B) and an item of information representative of a spatial image of the original multichannel signal that has been coded and then decoded (Inf. B). The invention also relates to a decoding method and a coding method implementing the determining method, and to the associated coding and decoding devices.
