  • Publication number: 20210056984
    Abstract: An apparatus and method of blind detection of binauralized audio. If the input content is detected as binaural, a second binauralization may be avoided. In this manner, the user experience avoids audio artifacts introduced by multiple binauralizations.

  • Patent number: 10932082
    Abstract: A system and method of modifying a binaural signal using headtracking information. The system calculates a delay, a first filter response, and a second filter response, and applies these to the left and right components of the binaural signal according to the headtracking information. The system may also apply headtracking to parametric binaural signals. In this manner, headtracking may be applied to pre-rendered binaural audio.

  • Patent number: 10659899
    Abstract: Embodiments are directed to a method of rendering adaptive audio by receiving input audio comprising channel-based audio, audio objects, and dynamic objects, wherein the dynamic objects are classified as sets of low-priority dynamic objects and high-priority dynamic objects, rendering the channel-based audio, the audio objects, and the low-priority dynamic objects in a first rendering processor of an audio processing system, and rendering the high-priority dynamic objects in a second rendering processor of the audio processing system. The rendered audio is then subject to virtualization and post-processing steps for playback through soundbars and other similar limited height capable speakers.

  • Publication number: 20190179604
    Abstract: Media input audio data corresponding to a media stream and microphone input audio data from at least one microphone may be received. A first level of at least one of a plurality of frequency bands of the media input audio data, as well as a second level of at least one of a plurality of frequency bands of the microphone input audio data, may be determined. Media output audio data and microphone output audio data may be produced by adjusting levels of one or more of the first and second plurality of frequency bands based on the perceived loudness of the microphone input audio data, of the microphone output audio data, of the media output audio data and the media input audio data. One or more processes may be modified upon receipt of a mode-switching indication.

  • Patent number: 9622010
    Abstract: Embodiments are directed to an interconnect for coupling components in an object-based rendering system comprising: a first network channel coupling a renderer to an array of individually addressable drivers projecting sound in a listening environment and transmitting audio signals and control data from the renderer to the array, and a second network channel coupling a microphone placed in the listening environment to a calibration component of the renderer and transmitting calibration control signals for acoustic information generated by the microphone to the calibration component. The interconnect is suitable for use in a system for rendering spatial audio content comprising channel-based and object-based audio components.

  • Patent number: 9532158
    Abstract: Embodiments are described for a system of rendering spatial audio content in a listening environment. The system includes a rendering component configured to generate a plurality of audio channels including information specifying a playback location in a listening area, an upmixer component receiving the plurality of audio channels and generating, for each audio channel, at least one reflected sub-channel configured to cause a majority of driver energy to reflect off of one or more surfaces of the listening area, and at least one direct sub-channel configured to cause a majority of driver energy to propagate directly to the playback location.

  • Patent number: 9483228
    Abstract: Non-media data relating to real-world objects or persons are collected from a scene while media data from the same scene are collected. The media data comprise audio data only or audiovisual data, whereas the non-media data comprise telemetry data and/or non-telemetry data. Based at least in part on the non-media data relating to the real-world objects or persons in the scene, emitter-listener relationships between a listener and some or all of the real-world objects or persons are determined. Audio objects comprising audio content portions and non-audio data portions are generated. At least one audio object is generated based at least in part on the emitter-listener relationships.
