摘要 通过对多路音频记录系统的硬件系统结构进行了分析,提出了音频记录设备软件的功能与架构设计方案,重点阐述了数据存储、导出、删除软件功能的设计思路。通过实时长时间测试,此软件协同系统硬件可实现2 MB/s的数据实时采集和记录,27 MB/s的数据导出,满足了客户的实际应用需求。 Based on the analysis of the hardware system structure of the multi-channel audio recording system, the function and architecture design of the audio recording equipment software is put forward, and the design idea of the function of data storage, export and delete software is expounded. After real-time long-time testing, the The hardware of the software cooperative system can realize the real-time data acquisition of 2 MB/s and record the data export of 27 MB/s, which meets the practical application needs of the customer.
