FIELD: audio signal encoding technology. ^ SUBSTANCE: in accordance to the method, at least a part of an audio signal is encoded to produce encoded signal, where the encoding includes encoding with prediction relatively to aforementioned at least a part of audio signal to produce prediction coefficients which represent time characteristics, such as time envelope curve, of aforementioned at least a part of audio signal, transformation of prediction coefficients to a set of times, which represent prediction coefficients, and inclusion of aforementioned set of times into encoded signal. For analysis/synthesis of overlapping frames relatively to time envelope curve, excessiveness in representation of linear spectrum for overlapping area may be used. ^ EFFECT: improved method for encoding at least a part of an audio signal. ^ 2 cl, 7 dwg
