Mechanism for retrieval of previously captured audio

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.
