| Abstract: | An implementation of audio streaming capture and mixing multiple audio streaming on network based on DirectSound tech-nology.Audio streaming capture adopts DirectSound's buffer mechanisms,while multi-sound mixing combines technologies related network with DirectSound's secondary buffer mechanisms.The scheme enhance the efficiency and generality of audio process.Some related technologies of DirectSound and the architecture of system are introduced,how to implement voice capture and mixing and the using of ring-buffer are described.Last,an optimization policy is proposed. |
