摘要： 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.

摘要： In some embodiments, a method for upmixing input audio comprising N full range channels to generate 3D output audio comprising N+M full range channels, where the N+M full range channels are intended to be rendered by speakers including at least two speakers at different distances from the listener. The N channel input audio is a 2D audio program whose N full range channels are intended for rendering by N speakers nominally equidistant from the listener. The upmixing of the input audio to generate the 3D output audio is typically performed in an automated manner, in response to cues determined in automated fashion from stereoscopic 3D video corresponding to the input audio, or in response to cues determined in automated fashion from the input audio. Other aspects include a system configured to perform, and a computer readable medium which stores code for implementing any embodiment of the inventive method.

摘要： There is provided encoding and decoding methods for encoding and decoding of object based audio. An exemplary encoding method includes inter alia calculating M downmix signals by forming combinations of N audio objects, wherein M≤5N, and calculating parameters which allow reconstruction of a set of audio objects formed on basis of the N audio objects from the M downmix signals. The calculation of the M downmix signals is made according to a criterion which is independent of any loudspeaker configuration.

摘要： Audio objects are associated with positional metadata. A received downmix signal comprises downmix channels that are linear combinations of one or more audio objects and are associated with respective positional locators. In a first aspect, the downmix signal, the positional metadata and frequency- dependent object gains are received. An audio object is reconstructed by applying the object gain to an upmix of the downmix signal in accordance with coefficients based on the positional metadata and the positional locators. In a second aspect, audio objects have been encoded together with at least one bed channel positioned at a positional locator of a corresponding downmix channel. The decoding system receives the downmix signal and the positional metadata of the audio objects. A bed channel is reconstructed by suppressing the content representing audio objects from the corresponding downmix channel on the basis of the positional locator of the corresponding downmix channel.
