Patent number: 11979723Abstract: A trained machine configured to input a stereo sound track and separate the stereo sound track into multiple N separated stereo audio signals respectively characterized by multiple N audio content classes. All stereo audio as input in the stereo sound track is included in the N separated stereo audio signals. A mixing module is configured to spatially localize symmetrically and without cross-talk, between left and right, the N separated stereo audio signals into multiple output channels. The output channels include respective mixtures of one or more of the N separated stereo audio signals. Gain is adjusted of the output channels into left and right binaural outputs to conserve summed levels of the N separated stereo audio signals distributed over the output channels.Type: GrantFiled: March 29, 2022Date of Patent: May 7, 2024Assignee: Waves Audio Ltd.Inventors: Itai Neoran, Matan Ben-Asher, Itamar Davidesco, Idan Egozy

Patent number: 11620771Abstract: Computing a relative-head-orientation relative to a moving-reference. First and second data are received. The first data are indicative of a head-orientation of a head of a user. The second data are indicative of at least one of: a location, a motion, an orientation, a velocity and an acceleration of the user. A head-orientation is computed according to the first data. A moving-reference is updated by an adjustment toward the head-orientation, to produce an updated-moving-reference. The amount of adjustment is indicated by processing the second data. A relative-head-orientation is computed relative to the updated-moving-reference. Binaural audio is rendered in accordance with the relative-head-orientation.Type: GrantFiled: November 1, 2021Date of Patent: April 4, 2023Assignee: Waves Audio Ltd.Inventors: Matan Ben-Asher, Meir Shashoua, Gal Alchanati, Nadav Nehoran

Patent number: 11425258Abstract: First and second computer systems and respective first and second microphones thereof receive respective portions of a same audio input signal. Audio buffers received respectively from the first and second computer system include data encoded from respective microphone inputs of the first and the second computer systems. The received audio buffers are synchronized and corrected for gain differences between the received audio buffers to produce corrected audio buffers. The corrected audio buffers are mixed into an output buffer. The synchronization reduces echo when the output buffer is played at a remote peer computer system.Type: GrantFiled: November 9, 2020Date of Patent: August 23, 2022Assignee: Waves Audio Ltd.Inventors: Nahum Noam Weissman, Matan Ben-Asher, Netanel Eyal, Amir Ben-Kiki
