FIELD: acoustics.
SUBSTANCE: invention relates to the audio signals encoding means. Generating at least one audio signal defining parameters at least one vector. Sorting the said at least one parameters vector components according to the descending order based on the said at least one parameter vector components absolute values to form at least one associated ordered parameters vector. Selecting at least one potential code vector from the master classes list. Determining the distance between at least one potential code vector and at least one ordered parameters vector. Determining at least one master class associated with the potential code vector, which forms the smallest associated distance. Sorting at least one master class by the reverse descending ordering based on the said at least one parameters vector components absolute values.
EFFECT: reducing the encoding complexity by the quantization distortion evaluation in the transposed vector space.
