Embodiments are disclosed for channel-based audio (CBA) (e.g., 22.2-ch audio) to object-based audio (OBA) conversion. The conversion includes converting CBA metadata to object audio metadata (OAMD) and reordering the CBA channels based on channel shuffle information derived in accordance with channel ordering constraints of the OAMD. The OBA with reordered channels is rendered in a playback device using the OAMD or in a source device, such as a set-top box or audio/video recorder. In an embodiment, the CBA metadata includes signaling that indicates a specific OAMD representation to be used in the conversion of the metadata. In an embodiment, pre-computed OAMD is transmitted in a native audio bitstream (e.g., AAC) for transmission (e.g., over HDMI) or for rendering in a source device. In an embodiment, pre-computed OAMD is transmitted in a transport layer bitstream (e.g., ISO BMFF, MPEG4 audio bitstream) to a playback device or source device.

A method for representing a second presentation of audio channels or objects as a data stream, the method comprising the steps of: (a) providing a set of base signals, the base signals representing a first presentation of the audio channels or objects; (b) providing a set of transformation parameters, the transformation parameters intended to transform the first presentation into the second presentation; the transformation parameters further being specified for at least two frequency bands and including a set of multi-tap convolution matrix parameters for at least one of the frequency bands.

A method of controlling spatial audio rendering includes comparing a first heartbeat pattern to a second heartbeat pattern to generate a comparison result. The first heartbeat pattern is based on sensor information associated with a first sensor of a first sensor type, and the second heartbeat pattern is based on sensor information associated with a second sensor of a second sensor type. The method also includes, based on the comparison result, controlling a spatial audio rendering function associated with media playback.

Various embodiments provide a multi-audio input, stereo audio output, push-to-talk (PTT) switch device. The device may include an audio processing unit configured to perform spatial separation/positioning for one or a plurality of audio sources. The audio processing unit of the device may apply unique head-related transfer functions (HRTFs) to produce left and right audio outputs that correspond to predetermined or dynamically positioned spatial locations for each of the incoming audio streams.

An apparatus including circuitry configured to: obtain a binaural audio signal; obtain, based on the binaural audio signal, at least one direction parameter of at least one frequency band of the binaural audio signal; process the binaural audio signal to generate at least two audio signals for loudspeaker reproduction by modifying an inter-channel difference of the at least one frequency band of the binaural audio signal based on the at least one direction parameter for the at least one frequency band; and output the at least two audio signals for loudspeaker reproduction.

An apparatus for generating loudspeaker signals includes an object metadata processor configured to receive metadata, to calculate a second position of the audio object depending on the first position of the audio object and on a size of a screen if the audio object is indicated in the metadata as being screen-related, to feed the first position of the audio object as the position information into the object renderer if the audio object is indicated in the metadata as being not screen-related, and to feed the second position of the audio object as the position information into the object renderer if the audio object is indicated in the metadata as being screen-related. The apparatus further includes an object renderer configured to receive an audio object and to generate the loudspeaker signals depending on the audio object and on position information.

A system for intelligent audio rendering using speaker nodes is provided. A source device determines a spatial location and speaker capability of one or more speaker nodes based on information embedded in a corresponding node of each of the one or more media devices, selects a first speaker most suitable for each audio channel based on the speaker capability and the spatial location of each of the one or more speakers, generates speaker profiles for the one or more speakers, maps an audio channel to each of the one or more speakers based on a speaker profile corresponding to each of the one or more speakers, estimates a media path between the source device and each of the one or more speakers, detects a change in the estimated media path, renders an audio on the one or more speakers based on the speaker profiles and the changes in the media paths corresponding to each of the one or more speakers in real-time.
