Methods and arrangements are disclosed for digitally encoding and decoding sound—An input signal is split () into a primary frequency band and at least one secondary frequency band. The parts of the input signal in the frequency bands are separately encoded. Certain characteristics of the input signal in the primary frequency band and corresponding characteristics of the input signal in at least one secondary frequency band are examined () in order to find out, whether there is certain resemblance therebetween. Alternatively certain characteristic features of the process applied to encoding the primary frequency band extracted () and used () in encoding the secondary frequency band, or such extracted characteristic features are replaced () with a locally generated, independent set of corresponding features.
