Patent abstract
Multiple kernel-mode audio processing modules or filters are combined to form a module or filter graph. The graph is implemented in kernel-mode, reducing latency and jitter when handling audio data (e.g., MIDI data) by avoiding transfers of the audio data to user-mode applications for processing. A variety of different audio processing modules can be used to provide various pieces of functionality when processing audio data.
