五、应用举例

首先将BasicDelay.dlb, BasicDelay.h两个文件拷贝到自己的工程目录下，然后将它们添加到工程中；然后在LDF文件中给数据段BDelay_dmda、程序段BDelay_pmco分配空间，接下来再写相关代码。

#include "BasicDelay.h"

#define NUM_SAMPLES 512 //输入数据块长度

/*************************************************************************

* 调用BasicDelay.dlb库函数需定义的参数

*************************************************************************/

// 延时的宏定义

#define DLine 4000 // Total Delay = DLine/fs 秒

// 定义两个声道的延时缓冲区大小

#define BufLengthL DLine

#define BufLengthR DLine

// 两个声道的延时缓冲区

#pragma section ("BDelay_dmda")

int DelayBufL[BufLengthL + 1];

#pragma section ("BDelay_dmda")

int DelayBufR[BufLengthR + 1];
