DECODER, ENCODER AND METHOD FOR INFORMED LOUDNESS ESTIMATION IN OBJECT-BASED AUDIO CODING SYSTEMS Russian patent published in 2018 - IPC G10L19/08 

FIELD: speech analysis or synthesis; speech recognition.

SUBSTANCE: invention relates to a method of encoding audio signals. Technical result is achieved by a decoder for generating an output audio signal comprising one or more audio output channels, the decoder comprising: a receiving interface for receiving an audio input signal; a signal processor for generating audio output channels, an output audio signal configured to determine a loudness compensation value depending on the loudness information and depending on the rendering information, generate the one or more audio output channels of the audio output signal from the audio input signal depending on the rendering information and depending on the loudness compensation value, so that the loudness of the audio output signal is equal to the loudness of the audio input signal, or so that the loudness of the audio output signal is closer to the loudness of the audio input signal than the loudness of the modified audio signal.

EFFECT: technical result is high efficiency of encoding, processing and decoding of audio signals.
