Patent number: 9858936Abstract: In some embodiments, a method for selecting at least one layer of a spatially layered, encoded audio signal. Typical embodiments are teleconferencing methods in which at least one of a set of nodes (endpoints, each of which is a telephone system, and optionally also a server) is configured to perform audio coding in response to soundfield audio data to generate spatially layered encoded audio including any of a number of different subsets of a set of layers, the set of layers including at least one monophonic layer, at least one soundfield layer, and optionally also at least one metadata layer comprising metadata indicative of at least one processing operation to be performed on the encoded audio. Other aspects are systems configured (e.g., programmed) to perform any embodiment of the method, and computer readable media which store code for implementing any embodiment of the method or steps thereof.Type: GrantFiled: September 11, 2013Date of Patent: January 2, 2018Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Richard James Cartwright, Glenn Dickins

Patent number: 9502046Abstract: A method for encoding sound field signals includes allocating coding rate by application of a uniform criterion to all subbands of all signals in a joint process. An allocation criterion may be based on a comparison, in a given subband, between a spectral envelope of the signals to be encoded and a coding noise profile, wherein the noise profile may be a sum of a noise shape and a noise offset, which noise offset is computed on the basis of the coding bit budget. The rate allocation process may be combined with an energy-compacting orthogonal transform, for which there is proposed a parameterization susceptible of efficient coding and having adjustable directivity. In a further aspect, the invention provides a corresponding decoding method.Type: GrantFiled: September 20, 2013Date of Patent: November 22, 2016Assignees: Dolby Laboratories Licensing Corporation, Dolby International ABInventors: Heiko Purnhagen, Leif Jonas Samuelsson, Janusz Klejsa, Lars Villemoes, Toni Hirvonen, Glenn N.
