  • Publication number: 20190253801
    Abstract: Embodiments are described for a method for localizing a set of speakers (106) and microphones (108), having only the times of arrival between each of the speakers and microphones. An autodiscovery process (107) uses an external input to set: a global translation (3 continuous parameters), a global rotation (3 continuous parameters), and discrete symmetries, i.e., an exchange of any axis pairs and/or reversal of any axis. Different time of arrival acquisition techniques may be used, such as ultrasonic sweeps or generic multitrack audio content. The autodiscovery algorithm is based in minimizing a certain cost function, and the process allows for latencies in the recordings, possibly linked to the latencies in the emission.

  • Publication number: 20190215540
    Abstract: Methods, systems, and computer program products for network-based processing and distribution of multimedia content of a live performance are disclosed. In some implementations, recording devices can be configured to record a multimedia event (e.g., a musical performance). The recording devices can provide the recordings to a server while the event is ongoing. The server automatically synchronizes, mixes and masters the recordings. The server performs the automatic mixing and mastering using reference audio data previously captured during a rehearsal. The server streams the mastered recording to multiple end users through the Internet or other public or private network. The streaming can be live streaming.

  • Patent number: 10136216
    Abstract: Methods and systems for generating an audio mix indicative of action sound captured at an event on a surface (e.g., a sporting event on a field) using a microphone array, where the array includes subsurface microphones (e.g., a large number of subsurface microphones) positioned under the surface, and optionally also other microphones. In typical embodiments, at least one point of interest (“PI”) on the surface is selected in an automated manner, PI data indicative of a currently selected PI on the surface is generated (e.g., a sequence of PIs on the surface is selected, the PI data is indicative of the sequence of PIs, and a most recently selected PI in the sequence is the currently selected PI), and the audio mix is generated in response to the PI data. Aspects include methods performed by any embodiment of the system, and a system or device configured (e.g., programmed) to perform any embodiment of the method.

  • Publication number: 20180295464
    Abstract: Diffuse or spatially large audio objects may be identified for special processing. A decorrelation process may be performed on audio signals corresponding to the large audio objects to produce decorrelated large audio object audio signals. These decorrelated large audio object audio signals may be associated with object locations, which may be stationary or time-varying locations. For example, the decorrelated large audio object audio signals may be rendered to virtual or actual speaker locations. The output of such a rendering process may be input to a scene simplification process. The decorrelation, associating and/or scene simplification processes may be performed prior to a process of encoding the audio data.

  • Publication number: 20180167756
    Abstract: Multiple virtual source locations may be defined for a volume within which audio objects can move. A set-up process for rendering audio data may involve receiving reproduction speaker location data and pre-computing gain values for each of the virtual sources according to the reproduction speaker location data and each virtual source location. The gain values may be stored and used during “run time,” during which audio reproduction data are rendered for the speakers of the reproduction environment. During run time, for each audio object, contributions from virtual source locations within an area or volume defined by the audio object position data and the audio object size data may be computed. A set of gain values for each output channel of the reproduction environment may be computed based, at least in part, on the computed contributions. Each output channel may correspond to at least one reproduction speaker of the reproduction environment.

  • Patent number: 9858932
    Abstract: Embodiments are directed to a method of representing spatial rendering metadata for processing in an object-based audio system that allows for lossless interpolation and/or re-sampling of the metadata. The method comprises time stamping the metadata to create metadata instances, and encoding an interpolation duration to with each metadata instance that specifies the time to reach a desired rendering state for the respective metadata instance. The re-sampling of metadata is useful for re-clocking metadata to an audio coder and for the editing audio content.

  • Patent number: 9843642
    Abstract: Geo origination data is generated for a geo-tagged media device of a user from measurements performed by sensors. The geo origination data is sent to a server system. At the server system, geo-tagged media content elements are selected based on the geo origination data. Further, based on the selected geo-tagged media content elements and the geo origination data, geo-referenced rendering data to be used for rendering media content from the selected geo-tagged media content elements perceivable to the user of the geo-tagged media device is generated. The geo-referenced rendering data can be streamed to the geo-tagged media device along with media content derived from the geo-tagged media content elements for rendering at the geo-tagged media device.

  • Publication number: 20170289724
    Abstract: During a process, decorrelation may be selectively applied to audio data for an audio object based, at least in part, on whether a speaker for which speaker feed signals will be determined is a surround speaker. In some implementations, decorrelation may be selectively applied according to whether such a speaker is a height speaker. Some implementations may reduce, or even eliminate, audio artifacts such as comb-filter notches and peaks. Some such implementations may increase the size of a “sweet spot” of a reproduction environment.

  • Patent number: 9712939
    Abstract: A gain contribution of the audio signal for each of the N audio objects to at least one of M speakers may be determined. Determining the gain contribution may involve determining a center of loudness position that is a function of speaker (or cluster) positions and gains assigned to each speaker (or cluster). Determining the gain contribution also may involve determining a minimum value of a cost function. A first term of the cost function may represent a difference between the center of loudness position and an audio object position.
