Abstract: Methods and systems provide control of media synchronization using time stamp pairs. In an embodiment, a first device may request a time stamp from a second device. The first device may determine any de-synchronization between the first and second devices based on the requested time stamp and characteristics of the request. The first device may define a rate scalar based on the determined de-synchronization. A sample rate conversion may be performed for the first device based on the rate scalar such that the outputs of the first device and the second device are synchronized.

Abstract: According to one embodiment, a media system communicates with an aggregate device that includes multiple media output devices. When providing media data for presentation, the system adjusts for device clock drift by resampling the media data provided to a media output device based at least in part on a device clock rate difference between a device clock of one of the media output devices and a device clock of another of the media output devices.

Abstract: In one aspect a device-side audio handling input/output unit (DIO) of a hardware device writes audio data generated by the hardware device within a ring buffer. An input provided by a user for activation of a software program is received, and a notification that the software program is ready to accept the audio data is generated. A system-side audio handling input/output unit (SIO) additionally provides past audio data from the ring buffer to the software program. Other aspects also are described.

Abstract: In one embodiment, a device-side audio handling input/output unit (DIO) of a microphone writes audio data generated by the microphone into a ring buffer. A system-side audio handling I/O unit (SIO) receives a request from a software program to consume past audio data from the ring buffer. The SIO provides the past audio data from the ring buffer to the software program. Other embodiments are also described and claimed.
