Abstract

DC60 (22/12/52) This invention deals with the field of audio coding. Especially Related to Transcoding the auditory metadata between different auditory encoding schemes, methods and systems for transcoding the auditory gain metadata associated with auditory amplification are described. Controls the dynamic range from the first gain metadata of the first auditory encoding scheme to be The second gain metadata of the second auditory encoding scheme. Where in the coding scheme The first and second hearing voices use the encoding block and where the encoding block has at least one complementary gain value. Method and a second gain metadata gain value is selected depending on the value. Metadata magnification First gain Where, within the interval while the time relative to the value Second magnification metadata The minimum gain of the metadata, the first gain is selected.
