IAudioClock interface (audioclient.h)
The IAudioClock interface enables a client to monitor a stream's data rate and the current position in the stream. The client obtains a reference to the IAudioClock interface of a stream object by calling the IAudioClient::GetService method with parameter riid set to REFIID IID_IAudioClock.
When releasing an IAudioClock interface instance, the client must call the interface's Release method from the same thread as the call to IAudioClient::GetService that created the object.
