Chengyu Bai · Journal of Mechanical & Electrical Engineering · 2010
According to the practical need of multimedia conference system,audio processing strategies were categorized,audio multi-point processing principle and the corresponding strategies in data transport layer and signal processing layer were introduced.A practical audio mixing algorithm was designed,which can effectively eliminate overflow,at the same time it can be able to make the greatest possible to prevent signal distortion.Finally,a well-behaved audio multi-point processor was realized.The results show that the processor can be used in the research of the H.323 multimedia conference system and it can also be employed as a reference model of the commercial multi-point teleconference.
