Patent number: 11100942Abstract: Systems and methods are described for compensating for inaccurate echo prediction in audio systems. A signal may be received at a microphone of an audio system, the signal including audio rendered using a spatial audio renderer across a multi-channel audio output. A signal may be received from the spatial audio renderer that indicates a change in rendering of audio. The audio system may then determine if there is echo power within the received signal greater than an expected echo power. After the signal from the spatial audio renderer has been received, the echo suppression applied to the received signal may be modified in response to a determination that the echo power is greater than the expected echo power, the echo suppression attenuating pre-selected frequency bands of the received signal.Type: GrantFiled: July 13, 2018Date of Patent: August 24, 2021Assignee: Dolby Laboratories Licensing CorporationInventors: Glenn N.

Patent number: 11029915Abstract: An audio signal processing graph is automatically recomposed to optimize its properties by reassigning and instantiating its nodes on available locales such that the number of inter-locale connections is minimized and latency between inputs, such a performer's live input, and outputs, such as a monitored recording mix, is minimized. The recomposition exploits associative, commutative, and decomposition properties of certain node types, including mixer nodes. A graph recomposition may decompose a mixer node into a first stage instantiated by a software plug-in hosted by a computer running a digital audio workstation in a first locale, and a second stage assigned to an audio processing device in a second locale. Automatic signal graph recomposition occurs when the system is initialized, the graph is reconfigured, a new desired behavior of the graph is specified, or the available network resources are changed.Type: GrantFiled: December 30, 2019Date of Patent: June 8, 2021Assignee: Avid Technology, Inc.Inventors: Paul A.
