Equipment and methods for creating encoded sound scenes, equipment and methods for processing encoded sound scenes, and non-transfer storage

Abstract

The term refers to devices that create encoded audio scenes and devices that decode and / or process encoded audio scenes; as well as related methods and non-forward storage that store coded instructions which, when executed by the processor, will cause the processor to perform the related method. The device (200) processes the encoded audio scene (304) which includes, in the first frame (346), the representation of the first 80 audio fields (316) and the encoded audio signal (346), in which the second frame (348) is an inactive frame, the device includes: an activity detector (2200) to detect the second frame (348) as an inactive frame; The synthesizer (210) synthesizes the synthesized audio signal (228) for the second frame (308) using the parameter description (348) for the second frame (308); the audio decoder (230) decodes the encoded audio signal (346) for the first frame (306); and spatial output (240) to output the audio signal (202) spatially for the first frame (306) using the first audio field parameter representation (316) and using the composite audio signal (228) for the second frame (308) or transcoder to create a metadata-supported output format including the audio signal (346) for the first frame (306), the first audio field parameter representation (316) for the first frame (306), composite audio signal (228) for second frame (308) and second audio field parameter representation (318) for second frame (308).
