Introduction

DSP-6464M next-generation intelligent digital audio processing server uses two processing chips with a main frequency of lGHz, which is the core device of the thermal computing power system platform. The thermal computing system platform is based on the rea-time Linux operating system, through independent research and development to achieve better localization functions, drag-and-drop module with a full-English operation interface, with diversiﬁed data processing capabilities, relying on the digital network environment to build for a variety of large-scale network audio application scenarios.
The server has network backup and dual-host backup functions, the backup mechanism is set by intelligent algorithms, to realize automatic backup, the main and subordinate server only need to ensure the exact same conﬁguration, it can achieve mirror backup through the system mechanism, based on the heartbeat signal and “static” and “moving” which is the perfect combination of physical backup and logical backup, to achieve node without vulnerabilities, uninterrupted system operation, and thus to ensure the security of the system.
The server contains 8 channels of 300ms AEC input channels, and also has 8 card slots that can be equipped with diﬀerent types of audio cards, 4-channel analog input cards, 4-channel analog input cards, 4-channel AEC cards,2-channel/4-channel USB sound cards, etc., to achieve full signal compatibility. A maximum of 32 analog channels are supported locally. Both integrated and independent channels oﬀer extremely high hardware quality, including frequency response, dynamic range and total harmonic distortion. The server supports 64×64 network transmission, the host supports custom board conﬁguration, and can be arbitrarily equipped with input, output card and AEC card, and the openness of the system and server is diversiﬁed to complete the use scenarios that meet user needs.
The system has a full-English operation interface, the control operation interface is simple and intuitive; in the control software, through simple mouse operation, you can complete the entire audio system parameters, plan setting and call The graphical control interface is one of the core of this system, and the signal is on spot and can be achieved by installing software on the computer.
