Abstract (en)
[origin: WO2012085410A1] The invention relates to processing a signal in the form of consecutive sample blocks (TRj, TRj+1), the method comprising filtering in a transformed domain of sub-bands, and particularly equalization processing (T0), applied to a current block (TRj) in the transformed domain, and filtering-adjustment processing (T1, ?'1) that is applied in the transformed domain to at least one block (TRj-1, TRj+1) adjacent to the current block.
