摘要
本文的多路音频采集系统以凌阳单片机SPCE061A为基础平台,以微型计算机的硬盘为存储媒介,可实现7路音频信号长时间的连续采集与存储。编程时直接引用SPCE061A丰富的音频压缩算法及API函数,减轻了编程工作量,可为多路大容量音频信号的采集与存储提供参考。
The multichannel audio collection system are based on single chip microcomputer sunplus SPCE061 A as the basic platform, using the computer＇s hard disk as storage media the system can realize 7channel audio signal long time continuous acquisition and storage. When programming directly are quoted SPCE061 A rich audio compression algorithm and the API function, it can reduce the workload for programming, and providve the reference for multichannel large capacity audio signal acquisition and storage.
