Mixing and splitting multiple independent audio data streams in kernel space

摘要

A method and an apparatus for securely mixing and splitting multiple audio data streams and determining the order of processing the audio streams. A audio server and an audio device driver are in kernel space of a given computer system. In one embodiment, the computer system has a data flow checker and adjuster for checking the flow of data into data queues and a setup application for connecting the audio server and the audio device driver. The data flow checker and adjuster adjusts the flow of data by sending a message up or downstream instructing the up or downstream processes/devices to send more data or stop sending data depending on how full the data queues are. <IMAGE>
