Study Of Networked Digital Audio Processor

The development of computer and networks have brought great impact on the traditional audio processing and transmission .Digital audio signal process gradually take the place of the analog audio signal process and turn into_mainstream.Because the tradition audio transmitting network has shortcomings such as hard to be managed,complicated fabric,hard to realize auto-switching ,the digital networks will be the future of the audio networks with no doubt.According to the requirements of professional and consumer audio equipment market, a network digital audio processor based on Cobranet and DSP is developed . The realtime performance of audio transmission of CM2(the hardware of Cobranet) and the high performance of ADSP21262 in processing and communication are combined in this processor. The content of this thesis is listed as follows:1 The strong-points and shortcomings of the analog and digital audio processing,the traditional and digital audio transmitting network was compared.2 Studied DSP algorithms in digital audio processing.3 Designed the system of the network digital audio processor based on Cobranet.4 Designed the software of the network digital audio processor based on Cobranet.5 Summarization and expectation.
