Patent number: 11531519Abstract: Adjusting gains of an audio mix. Audio tracks using respective gains are individually analyzed to compute a first metric of frequency content. A user input specifies a desired second metric of the frequency content. Responsive to the user input, respective gains of the audio tracks are collectively and simultaneously adjusted to produce respective adjusted gains of the audio tracks. A second audio mix when played of the audio tracks with the respective adjusted gains has a third metric of frequency content different from the first metric of frequency content. The third metric is closer to the second metric than said first metric.Type: GrantFiled: June 20, 2021Date of Patent: December 20, 2022Assignee: Waves Audio Ltd.Inventors: Inon Beiser, Meir Shaashua, Itai Neoran, Shai Mantzur
