摘要： An audio renderer comprises a receiver (801) receiving input data comprising early part data indicative of an early part of a head related binaural transfer function; reverberation data indicative of a reverberation part of the transfer function; and a synchronization indication indicative of a time offset between the early part and the reverberation part. An early part circuit (803) generates an audio component by applying a binaural processing to an audio signal where the processing depends on the early part data. A reverberator (807) generates a second audio component by applying a reverberation processing to the audio signal where the reverberation processing depends on the reverberation data. A combiner (809) generates a signal of a binaural stereo signal by combining the two audio components. The relative timing of the audio components is adjusted based on the synchronization indication by a synchronizer (805) which specifically may be a delay.

摘要： A transmitting device comprises a binaural circuit (601) which provides a plurality of binaural rendering data sets, each binaural rendering data set comprising data representing parameters for a virtual position binaural rendering. Specifically, head related binaural transfer function data may be included in the data sets. A representation circuit (603) provides a representation indication for each of the data sets.

摘要： An apparatus for processing an audio signal comprises an audio receiver (601) for receiving a set of input audio signals and a reference receiver (609) for receiving a reference reverberation for a rendering of the audio signal. A reverberation processor (607) determines an environment reverberation of an acoustic rendering environment and an audio processor (603) generates a set of output audio signals for a set of audio transducers (605) by processing the set of input audio signals. The audio processor (603) is arranged to modify reverberation for the set of input audio signals when generating the set of output audio signals, with the modification being dependent on the environment reverberation and the reference reverberation. The modification may specifically be such that the total overall reverberation matches the reference reverberation. The invention may provide increased control, e.g. by a content provider, over the audio environment experienced by a user.

摘要： An audio processing apparatus comprises a receiver (705) which receives audio data including audio components and render configuration data including audio transducer position data for a set of audio transducers (703). A renderer (707) generating audio transducer signals for the set of audio transducers from the audio data. The renderer (7010) is capable of rendering audio components in accordance with a plurality of rendering modes. A render controller (709) selects the rendering modes for the renderer (707) from the plurality of rendering modes based on the audio transducer position data. The renderer (707) can employ different rendering modes for different subsets of the set of audio transducers the render controller (709) can independently select rendering modes for each of the different subsets of the set of audio transducers (703). The render controller (709) can select the rendering mode for a first audio transducer of the set of audio transducers (703) in response to a position of the first audio transducer relative to a predetermined position for the audio transducer. The approach may provide improved adaptation, e.g. to scenarios where most speakers are at desired positions whereas a subset deviate from the desired position(s).

摘要： An apparatus generates signals for audio transducers from an audio signal so that the audio signal can be spatially rendered. The apparatus comprises a receiver (603) which receives position data indicating a desired rendering position for the audio signal. A drive signal generator (605) generates a first drive signal for a first audio transducer associated with a first position and a second drive signal for a second audio transducer associated with a second position. The first and second signals are generated using a panning operation for the audio signal based on to the desired rendering position. The drive signal generator (605) furthermore decorrelates the first drive signal relative to the second drive signal. The degree of decorrelation depends on the first position, and may specifically depend on the distance (including angular distance) of the speakers and/or the desired rendering position. The invention may reduce the perceptibility of artifacts introduced due to the panning.

摘要： An encoder (501) generates data representing an audio scene by a first downmix and data characterizing audio objects. In addition, a direction dependent diffuseness parameter indicative of a degree of diffuseness of a residual downmix is provided where the residual downmix corresponds to a downmix of audio components of the audio scene with the audio objects being extracted. A rendering apparatus (503) comprises a receiver (701) receiving the data from the encoder (501). A circuit (703) generates signals for a spatial speaker configuration from the audio objects. A transformer (709) generates non- diffuse sound signals for the spatial speaker configuration by applying a first transformation to the residual downmix and another transformer (707) generates signals for the spatial speaker configuration by applying a second transformation to the residual downmix by applying a decorrelation to the residual downmix. The transformations are dependent on the direction dependent diffuseness parameter. The signals are combined to generate an output signal.

摘要： A transmitting apparatus generates an audiovisual content item data stream (e.g. transport stream) comprising a plurality of individual audiovisual data streams with audiovisual components for the content item. A generator (301-307) generates a first stream comprising both mandatory audio data and replaceable audio data for the audio representation where the replaceable audio data being data can be replaced by alternative audio data. A combiner (309) includes the resulting stream into the content item data stream. A receiving apparatus includes an extractor (403) which extracts the mandatory audio data from the received stream. A replacer (415) may replace the replaceable audio data by alternative audio data and an output (415) can generate an audio signal from the mandatory and alternative audio data. The approach may specifically provide an improved and more flexible data stream for audiovisual content.

摘要： An audio apparatus comprises a receiver (605) for receiving audio data and audio transducer position data for a plurality of audio transducers (603). A renderer (607) renders the audio data by generating audio transducer drive signals for the audio transducers (603) from the audio data. Furthermore, a clusterer (609) clusters the audio transducers into a set of clusters in response to the audio transducer position data and to distances between audio transducers in accordance with a distance metric. A render controller (611) adapts the rendering in response to the clustering. The apparatus may for example select array processing techniques for specific subsets that contain audio transducers that are sufficiently close. The approach may allow automatic adaptation to audio transducer configurations thereby e.g. allowing a user increased flexibility in positioning loudspeakers.

摘要： A receiver (603) receives a position given by a first value representing a first position parameter and a second value representing a second position parameter. A match circuit (605) determines if the second value matches a nominal value. If so, an output circuit (609) generates output data including data representing the first value in a field of the output data but not including data representing the second value in the output data. Otherwise, the output circuit (609) includes data in the field which represents an invalid position value for the first position parameter. A receiver determines if data of a data field represents a valid position value for the first position parameter. If so, it determines a position with the first value being the valid position value and the second value being a nominal value for the second position parameter. Otherwise it determines the second value from a second field of the input data.
