A method is provided for encoding a digital signal as an encoded signal. The method includes performing a plurality of localized encodings of a digital signal to generate a set of encoded local signals. Localized encodings are performed for a first sample of the digital signal. A plurality of physical quantities is assigned to the first sample. The set of encoded local signals includes an encoded local signal associated with each physical quantity of the plurality of physical quantities. The method further includes analyzing a characteristic associated with an encoded signal to determine a measured value of the characteristic. The encoded signal includes the set of encoded local signals. The method also includes adjusting a first encoding parameter associated with the plurality of localized encodings according to the measured value of the characteristic and a target value of the characteristic. The first encoding parameter is adjusted for a second sample of the digital signal. The second sample is processed after the first sample.
