FIELD: physics, acoustics.
SUBSTANCE: invention relates to audio signal estimation means. The apparatus includes a unit for determining a codebook from a plurality of codebooks as an identified codebook. In the apparatus, an audio signal is encoded using the identified codebook and an estimation unit, which is configured to obtain a level value associated with the identified codebook as the obtained level value and for estimating the level of the audio signal using the obtained level value.
EFFECT: high efficiency of encoding an audio signal.
