CONVERTING AUDIO SIGNALS CAPTURED IN DIFFERENT FORMATS TO A REDUCED NUMBER OF FORMATS TO SIMPLIFY ENCODING AND DECODING OPERATIONS Russian patent published in 2023 - IPC G10L19/08 

FIELD: computer technology.

SUBSTANCE: computer technology for audio signal processing. Invention is proposed to ensure the conversion of audio signals captured in various formats into a limited number of formats that can be processed by the codec. The technical result is achieved due to the reception by the simplification unit in the transmitter of audio signals in a variety of audio presentation formats from the audio pre-processing unit; receiving of the attributes of the receiving device from the receiving device by the simplifying unit, wherein the attributes contain indications of one or more audio formats supported by the receiving device, wherein the one or more audio formats include at least one of a mono format, a stereo format, or a spatial format; converting by the audio simplifier to an acquisition format that is an alternative representation of one or more audio formats; and providing the simplifier of the converted audio signal to the coding unit for processing in the downstream direction, encoding the coding unit of the audio signal in the receive format into the encoded audio signal in the transmit format decoded by the receiving device.

EFFECT: ensuring the conversion of audio signals captured in various formats into a limited number of formats that can be processed by the codec.
