Study And Realization On The Network Acoustic Processor

Acoustical spreading system includes two parts, acoustical environmentand acoustical spreading equipments. The network acoustic processor is akind of acoustical spreading equipments. Its main purpose is to replace allacoustical spreading equipments between audio source and loudspeakers. Inthe thesis, firstly introduce the history of acoustical spreading system and themeaning of development of the network acoustic processor. Then clarify therole and internal structures of the equipment in acoustical spreading system.Finally, focus on the detailed description of the two basic modules. Towardsnetwork transmit module, two networks transmit problem are introduced,synchronous problem and audio transmit problem. And for audio frequencydispose module, how to carry out simulated analysis on specified arithmeticusing simulated tools is mainly described, and also get an authenticconclusion.I have made a deeply analysis on the related contents of the networkacoustic processor, and given out my understanding on the whole equipmentsdevelopment process and the results. Details list following,Aim at the synchronous problem for network transmission, put forward aviable solution which has been applied to practical application and got theapprobation of the customer.Analyze the transmit protocol (CobraNet), which provides the basis forfurther oneself development. Give out an extensive method of the CobraNet,which is very helpful for engineers to carry out system development.Put forward a new kind of new EQ method, its meaning lies in that thevariety of the audio frequency can be realized directly from the frequencydomain side, simplify the accumulation noise brought from the realization ofcomplicated filter in the past, also increase extensive of the arithmetic.
