Study And Realization Of Realtime Voice Transmission System Buffer Model

Audio process technologies started from the end of 19th century, Today the technologies are relatively mature. In the world Demand for audio product have increased sharply, especially audio technology products applied in internet transmission gained great momentum. But with the development of internet, audio process technologies are posed new demands and challenges.In these years the research of audio process technologies have been dedicated in two aspects. The first aspect is terminal audio technologies research, including compression coding technology and speech recognition technology. For example, MP3 technology and Affective Speech Processing, etc. The second aspect is real time speech process technology, for example VoIP technology, Typical Representatives such as SKYPE and MSN Messager are the hot research topics. However, in these technology researches most focus on Real-Time Communication based on Internet platform. The research of improving communication quality, especially making use of terminal Compensation to optimize communication quality(such as reduce delay and chop),is still lack. So ensuring audio communication quality and improving real-time performance are the Interactive audio key technologies. These researches are important for audio process technologies progress and application.In this paper, a digital real-time audio transmission system based on PSTN is proposed, a model of real-time audio transmission system barrel-shaped buffer is produced, And the mathematical expression is...
