摘要： Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object-based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data This configuration allows for the sound to be rendered according to an allocentric frame of reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent. The object position metadata contains the appropriate allocentric frame of reference information required to play the sound correctly using the available speaker positions in a room that is set up to play the adaptive audio content.

摘要： : Improved tools for authoring and rendering audio reproduction data are provided. Some such authoring tools allow audio reproduction data to be generalized for a wide variety of reproduction environments. Audio reproduction data may be authored by creating metadata for audio objects. The metadata may be created with reference to speaker zones. During the rendering process, the audio reproduction data may be reproduced according to the reproduction speaker layout of a particular reproduction environ-ment.

摘要： The invention is directed to a method, which comprises receiving audio reproduction data comprising one or more audio objects and metadata associated with each of the one or more audio objects; receiving reproduction environment data comprising an indication of a number of reproduction speakers in the reproduction environment and an indication of the location of each reproduction speaker within the reproduction environment; and rendering the audio objects into one or more speaker feed signals by applying an amplitude panning process to each audio object, wherein the amplitude panning process is based, at least in part, on the metadata associated with each audio object and the location of each reproduction speaker within the reproduction environment, and wherein each speaker feed signal corresponds to at least one of the reproduction speakers within the reproduction environment. The metadata associated with each audio object includes audio object coordinates indicating the intended reproduction position of the audio object within the reproduction environment and zone constraint metadata indicating whether rendering the audio object involves imposing speaker zone constraints.

摘要： Embodiments are described for an adaptive audio system that processes audio data comprising a number of independent monophonic audio streams. One or more of the streams has associated with it metadata that specifies whether the stream is a channel-based or object 5 based stream. Channel-based streams have rendering information encoded by means of channel name; and the object-based streams have location information encoded through location expressions encoded in the associated metadata. A codec packages the independent audio streams into a single serial bitstream that contains all of the audio data. This configuration allows for the sound to be rendered according to an allocentric frame of 10 reference, in which the rendering location of a sound is based on the characteristics of the playback environment (e.g., room size, shape, etc.) to correspond to the mixer's intent. The object position metadata contains the appropriate allocentric frame of reference information required to play the sound correctly using the available speaker positions in a room that is set up to play the adaptive audio content. 102 104 106 108 110 Pre- Authoring Hybrid User Capture Processing Tools Audio Rendering Experience Codec CHANNELS OBJECTS ADAPTIVE AUDIO MIX -------------- A ---- A -------- -- -- - -- - -- --- -A -- --------A - A -------A--- r-206 CHANNEL DATA +

摘要： Un método para renderizar audio para su reproducción a través de unos auriculares (116) utilizados por un oyente, que comprende: recibir contenido de audio digital que incluye audio basado en canales y en objetos; recibir metadatos dependientes del contenido generados por una herramienta de autoría (102) que procesa el contenido de audio digital recibido, en el que los metadatos dependientes del contenido controlan una pluralidad de características de canal y objeto e incluyen posiciones de objetos de audio en el audio basado en objetos; caracterizado por que el método comprende además recibir datos de sensor (316; 336) proporcionados por una pluralidad de sensores instalados en los auriculares (116), incluyendo dichos datos de sensor parámetros angulares y posicionales (r, θ, Φ) asociados con la cabeza del oyente; y renderizar el contenido de audio digital en respuesta a una combinación de los metadatos dependientes del contenido y los datos de sensor; en donde los metadatos dependientes del contenido comprenden además una bandera que indica que se aplique seguimiento de la cabeza a un objeto, y en donde el paso de renderizar el contenido de audio digital incluye, para dicho objeto al cual se indica que se ha de aplicar seguimiento de la cabeza, la modificación de una posición de dicho objeto en respuesta a los parámetros angulares y posicionales recibidos (r, θ, Φ).
