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。
Common digital audio applications to the real-time processing of voice signals as the goal, in special occasions, high-speed voice dump technology to take more simulation techniques to achieve, so there are drawbacks. In this paper, high-speed tape transcription, the use of DSP technology to study the multi-channel high-speed voice multi-channel digital-analog conversion technology to achieve a high-speed voice processing circuit design. This study is of practical significance to multi-channel high-speed data acquisition system.
