摘要:
从音频工具的应用特点出发,分析了多媒体会议音频处理的关键技术.在此基础上,设计了音频工具NAT(Network Audio Tool),并采用分离策略的软件模型在Linux操作系统上予以实现.对NAT实现过程中的缓存管理问题和系统性能进行了简单的分析,并指出存在的不足和将来的研究方向.
Abstract:
From the application viewpoint, the key issues focused on audio processing were analyzed in the paper. Based on the analysis, we designed a network audio tool named NAT (Network Audio Tool) and implemented it based on the split policy under the Linux OS. Finally, a simple performance analysis of the NAT tool was given. We also pointed out the problems existed in out NAT system and discussed the future research work about packet audio.
