Abstract: Various embodiments provide an ability to describe, independent of a programming language, one or more interfaces associated with an operating system. Alternately or additionally, a compiler associated with a specific programming language can be configured to map the independent interface description(s) to the specific programming language. In some embodiments, an application can be configured to programmatically determine one or more interfaces of the operating system.

Abstract: Various embodiments provide techniques for allowing an application to opt out of system default audio stream behavior, as well as techniques for notifying applications on a computing device that a communication audio stream has been initiated. The techniques may differentiate between communication-related audio streams and audio streams that are not communication-related. In some embodiments, an application may register to receive notification that a communication stream has been initiated. The application may be configured to comply with system default audio stream handling policies, or it can perform custom behavior in response to the audio stream notification. In some embodiments, an application may register for filtered or unfiltered notification. In a filtered notification scenario, an application is notified that a communication stream has been initiated when an audio stream associated with the application has not already been modified in response to the initiation of a different communication stream.

Abstract: Systems and methods for parsing flexible audio codec topologies are described. In one aspect, codec topology information is obtained from an audio codec. The codec topology information includes a list of processing node connections and configuration default data for respective processing nodes associated with the audio codec. The codec topology information is evaluated to identify valid audio codec topologies based on set of valid connection path criteria.

Abstract: An audio signal processing device has input and output devices, a processor, an accelerator device in communication with the foregoing, and a memory for a storing a driver containing multiple filters of an audio filter graph. The driver controls the accelerator device. The filters contained within the driver can be executed by the accelerator device. Each filter transforms and outputs audio data in a predetermined manner. One filter mixes audio data received by the input device and another renders the mixed audio data for output by the output device. Global effect filters and acoustic cancellation filters can follow the mixing filter to, respectively, achieve a global effect on all input audio data and to cancel echoes therefrom.
