Patent number: 11962279Abstract: In some embodiments, a method for processing an audio signal in an audio processing apparatus is disclosed. The method includes receiving an audio signal and a parameter, the parameter indicating a location of an auditory event boundary. An audio portion between consecutive auditory event boundaries constitutes an auditory event. The method further includes applying a modification to the audio signal based in part on an occurrence of the auditory event. The parameter may be generated by monitoring a characteristic of the audio signal and identifying a change in the characteristic.Type: GrantFiled: June 1, 2023Date of Patent: April 16, 2024Assignee: Dolby Laboratories Licensing CorporationInventors: Brett G.

Publication number: 20220295207Abstract: A method for generating mastered audio content, the method comprising obtaining an input audio content comprising a number, M1, of audio signals, obtaining rendered presentation of the input audio content, the rendered presentation comprising a number, M2, of audio signals, obtaining a mastered presentation generated by mastering the rendered presentation, comparing the mastered presentation with the rendered presentation to determine one or more indications of differences between the mastered presentation and the rendered presentation, modifying one or more of the audio signals of the input audio content based on the indications of differences to generate the mastered audio content. With this approach, conventional, typically stereo, channel-based mastering tools can be used to provide a mastered version of any input audio content, including object-based immersive audio content.Type: ApplicationFiled: July 7, 2020Publication date: September 15, 2022Applicant: Dolby Laboratories Licensing CorporationInventors: Dirk Jeroen BREEBAART, David Matthew COOPER, Giulio CENGARLE, Brett G.

Publication number: 20220262387Abstract: Methods, systems, and computer program products of automatic de-essing are disclosed. An automatic de-esser can be used without manually setting parameters and can perform reliable sibilance detection and reduction regardless of absolute signal level, singer gender and other extraneous factors. An audio processing device divides input audio signals into buffers each containing a number of samples, the buffers overlapping one another. The audio processing device transforms each buffer from the time domain into the frequency domain and implements de-essing as a multi-band compressor that only acts on a designated sibilance band. The audio processing device determines an amount of attenuation in the sibilance band based on comparison of energy level in sibilance band of a buffer to broadband energy level in a previous buffer. The amount of attenuation is also determined based on a zero-crossing rate, as well as a slope and onset of a compression curve.Type: ApplicationFiled: April 29, 2022Publication date: August 18, 2022Inventors: Giulio Cengarle, Antonio Mateos Sole, Brett G.

Patent number: 11277703Abstract: 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.Type: GrantFiled: August 11, 2020Date of Patent: March 15, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Brett G. Crockett, Spencer Hooks, Alan Seefeldt, Joshua B. Lando, C. Phillip Brown, Sripal S. Mehta, Stewart Murrie

Patent number: 11064308Abstract: Embodiments are directed to upward-firing speakers that reflect sound off a ceiling to a listening location at a distance from a speaker. The reflected sound provides height cues to reproduce audio objects that have overhead audio components. A virtual height filter based on a directional hearing model is applied to the upward-firing driver signal to improve the perception of height for audio signals transmitted by the virtual height speaker to provide optimum reproduction of the overhead reflected sound. The upward firing driver is tilted at an inclination angle of approximately 20 degrees to the horizontal axis of the speaker and separate height and direct terminal connections are provided to interface to an adaptive audio rendering system.Type: GrantFiled: July 28, 2020Date of Patent: July 13, 2021Assignee: Dolby Laboratories Licensing CorporationInventors: Brett G.
