ABSTRACT:
An audio application programming interface (API) enables an audio processing graph to be modified during processing. If they are received while the audio graph is playing or paused, graph modifying commands may be inserted into either an asynchronous command queue or a deferred command queue. The audio API may also include a clock manager for synchronizing clocks from a number of different connected audio rendering devices, applications, processors, functions, operations, modules, or other resources. The clock manager may provide an interface that enables a number of control groups to be defined. Each such control group may include a master clock, a slave clock, and a control.
