本程序将指定的16K采样的语音数据文件转换为经G.723编解码后的8K语音数据。降采样前先使用180阶的FIR滤波器对语音数据进行频率压缩，然后进行抽取，并对抽取的数据进行G.723编解码。该程序在非特定语音识别的库文件处理中使用，也可扩展至其他用途。-this procedure will be designated the 16K sampling voice data files converted to G.723 codecs by the 8K words Music data. S

初学者可往下看本例程的原理： 1、依次获得取样点的颜色 2、在取样点画该颜色的方框 取样越精，方框越小，图像就越清晰 -Beginners can look down the principles of this routine: 1, followed by access to the color of sampling points 2, stipple the colors in the sampling of the more refined sampling box,
