FIELD: electrical communication engineering.
SUBSTANCE: invention relates to means for encoding, decoding and outputting an audio signal. Calculate the distance between the position of the ideal loudspeaker playing the audio signal and the position of the real loudspeaker playing the audio signal. Audio reproduction gain is calculated based on the specified distance. Adjust the gain of the audio signal based on the reproduction gain. Reproduction gain is adjusted based on the ratio between the total output sound power and the total input sound power. Moreover, the total output sound power is based on the audio signal subjected to the gain adjustment by the playback gain factor.
EFFECT: technical result is improved audio signal quality.
