Publication number: 20230091218Abstract: 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: ApplicationFiled: November 30, 2022Publication date: March 23, 2023Inventors: C. Phillip Brown, Joshua Brandon Lando, Mark F. Davis, Alan J. Seefeldt, David Matthew Cooper, Dirk Jeroen Breebaart, Rhonda Wilson

Publication number: 20230009878Abstract: Some implementations involve determining a noise metric and/or a speech intelligibility metric and determining a compensation process corresponding to the noise metric and/or the speech intelligibility metric. The compensation process may involve altering a processing of audio data and/or applying a non-audio-based compensation method. In some examples, altering the processing of the audio data does not involve applying a broadband gain increase to the audio signals. Some examples involve applying the compensation process in an audio environment. Other examples involve determining compensation metadata corresponding to the compensation process and transmitting an encoded content stream that includes encoded compensation metadata, encoded video data and encoded audio data from a first device to one or more other devices.Type: ApplicationFiled: December 9, 2020Publication date: January 12, 2023Applicant: Dolby Laboratories Licensing CorporationInventors: Timothy Alan PORT, Daniel Steven TEMPLETON, Jack Gregory HAYS, David Matthew COOPER

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.
