FIELD: information technology.
SUBSTANCE: audio encoding device (100) for encoding coefficient segments, having different time or frequency resolution of the selected audio signal includes a processor (110) for obtaining encoding context for the current encoded coefficient of the current segment based on the pre-encoded coefficient of the previous segment of a pre-encoded coefficient, having a different time or frequency resolution from the current encoded coefficient. The audio encoding device (100) also has an entropy (120) encoding device which encodes the current coefficient based on the encoding context to obtain an encoded audio stream.
EFFECT: improved encoding efficiency.
