Patent number: 12273702Abstract: 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.Type: GrantFiled: November 30, 2022Date of Patent: April 8, 2025Assignee: Dolby Laboratories Licensing CorporationInventors: C. Phillip Brown, Joshua Brandon Lando, Mark F. Davis, Alan J. Seefeldt, David Matthew Cooper, Dirk Jeroen Breebaart, Rhonda Wilson

Patent number: 12164832Abstract: 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.Type: GrantFiled: July 12, 2023Date of Patent: December 10, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Mark Alexander, Chunjian Li, Joshua Brandon Lando, Alan J. Seefeldt, C. Phillip Brown, Dirk Jeroen Breebaart

Patent number: 11929091Abstract: 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.Type: GrantFiled: March 1, 2022Date of Patent: March 12, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Chunmao Zhang, Lianwu Chen, Ziyu Yang, Joshua Brandon Lando, David Matthew Fischer, Lie Lu

Patent number: 11765535Abstract: 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.Type: GrantFiled: November 24, 2021Date of Patent: September 19, 2023Assignee: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Joshua Brandon Lando, Freddie Sanchez, Alan J.

Patent number: 11509987Abstract: An audio processing method may involve receiving media input audio data corresponding to a media stream and headphone microphone input audio data, determining a media audio gain for at least one of a plurality of frequency bands of the media input audio data and determining a headphone microphone audio gain for at least one of a plurality of frequency bands of the headphone microphone input audio data. Determining the headphone microphone audio gain may involve determining a feedback risk control value, for at least one of the plurality of frequency bands, corresponding to a risk of headphone feedback between at least one external microphone of a headphone microphone system and at least one headphone speaker and determining a headphone microphone audio gain that will mitigate actual or potential headphone feedback in at least one of the plurality of frequency bands, based at least partly upon the feedback risk control value.Type: GrantFiled: September 9, 2019Date of Patent: November 22, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Glenn N.
