基于DSP技术的多路语音“超实时”采集与压缩系统设计

The Research on High-multiple Speed Digital Voice on DSP

常见数字音频的应用以对语音信号实时处理为目标,特殊场合中语音高速转储方法多采取模拟技术来实现,因而存在弊端。本文对高速磁带复录,采用DSP技术,研究高倍速下的语音多通道数模转换技术,实现了一种高倍速语音处理电路设计。本研究对多路高速数据采集系统有实际意义。

Normal applications of digital audio take real-timing controlling as their object, whilst in special case, analog technology is used to restore audio signal quickly in special case, which has a lot of limitation. In this article, DSP technology is used in high speed tape’s copying and D/A and A/D converting technology is studied with muti-channel in high speed. A circuit was realized to deal with high speed audio. It is useful on muti-channel’s data collection in high speed.
