G10L 19/20

Abstract:

Methods for generating an object based audio program which is renderable in a personalizable manner, e.g., to provide an immersive, perception of audio content of the program. Other embodiments include steps of delivering (e.g., broadcasting), decoding, and/or rendering such a program. Rendering of audio objects indicated by the program may provide an immersive experience. The audio content of the program may be indicative of multiple object channels (e.g., object channels indicative of user-selectable and user-configurable objects, and typically also a default set of objects which will be rendered in the absence of a selection by a user) and a bed of speaker channels. Another aspect is an audio processing unit (e.g., encoder or decoder) configured to perform, or which includes a buffer memory which stores at least one frame (or other segment) of an object based audio program (or bitstream thereof) generated in accordance with, any embodiment of the method.

International Classification:

H04R 3/12
G06F 3/16
H04S 7/00

Abstract:

A system and method of providing a signal to wireless speakers. An audio stick connects to a source device and provides the audio signal to the wireless speakers. The audio stick combines the functionality of two separate devices: an audio receiver device and a transmitter device for the wireless speakers.

H04S 3/00

Abstract:

Embodiments are described for rendering spatial audio content through a system that is configured to reflect audio off of one or more surfaces of a listening environment. The system includes an array of audio drivers distributed around a room, wherein at least one driver of the array of drivers is configured to project sound waves toward one or more surfaces of the listening environment for reflection to a listening area within the listening environment and a renderer configured to receive and process audio streams and one or more metadata sets that are associated with each of the audio streams and that specify a playback location in the listening environment.

International Classification:

G10L 19/018
G10L 19/008

Abstract:

A method for selecting a subset of channels of (e.g., determined from) at least a segment of a multichannel audio program for watermarking and watermarking the selected subset of channels, and a system or device configured to implement any embodiment of the method, or including a buffer which stores at least one frame or other segment of a multichannel audio program generated by any embodiment of the method or steps thereof. Some embodiments generate watermarking metadata during program creation including by analyzing audio content to be included in segments of a multichannel program, determining at least one watermark suitability value for each channel of each of the segments, and including the watermark suitability values (or watermarking data determined therefrom) as metadata in the program. Some embodiments are implemented by a playback system which determines the selected subset of channels to be watermarked.

International Classification:

G10L 19/008
H04S 3/00

Abstract:

A low-quality rendition of a complex soundtrack is created, synchronized and combined with the soundtrack. The low-quality rendition may be monitored in mastering operations, for example, to control the removal, replacement or addition of aural content in the soundtrack without the need for expensive equipment that would otherwise be required to render the soundtrack.
