AoIP (Audio over IP) refers to the technology of transmitting uncompressed audio signals via IP within a regular local area network, characterized by high fidelity, low latency, and large capacity. AoIP uses mature IP protocol and IEEE1588 as the media clock synchronization scheme to achieve synchronous transmission of audio data among nodes in the network, eliminating data loss and delay caused by sampling rate differences.
AES67 solves the docking problem of AoIP streams, while AES70 is the control protocol. The combination of AES67 and AES70 serves the AoIP system. Through AES70, AoIP control functions such as device discovery, media stream monitoring and removal, device configuration and manipulation, system monitoring and management can be completed in the network; In addition, AES70 can also be applied to the monitoring and management of Ethernet based audio devices, including signal processing (gain, dynamics, equalization, mixing, etc.), level monitoring, spectrum analysis, snapshot management, and even remote reset and upgrade of devices.
With the official promulgation and implementation of the broadcasting and television industry standards GY/T304-2016 (AES67) and GY/T322-2019 (AES70), the mainstream technical route for the development of AoIP in China has been established, laying a solid foundation for building a compliant, open, stable, mixable, and deeply managed AoIP application system.
Fuchuan Technology's "AES67+AES70 Core Platform" is an AoIP basic solution developed based on the two major standards of the AES International Audio Engineering Association for network audio applications - AES67-2018 (Interoperability Specification for Streamed Audio) and AES70-2018 (Open Control Architecture for Network Audio). It includes various embedded modules such as FPGA, DSP, MCU designed for different application scenarios and scales, as well as driver layer link libraries, middleware, etc.
