直接读取wav文件是int数组,但是有一些实现返回的是double数组,还有些输入是double数组:那我们要互相调用的时候还是要看看两者到底有什么关系,其实很简单. 以单身道,16bit为例 /** * For Mono, 16bit, only! * @author karl * */ public class BasicIntDoubleConvetor { private static final float floatScale = 32768; public double[] arr

学了数组之后,感觉有好多操作需要经常去写,很不方便,因此自己做了一个工具类,方便调用,方法可能不全,希望大家可以添加,让我使用也方便一点儿. public class ArrayUtils { //求数组的最大值(int) public static int getMax(int[] arr){ int max = arr[0]; for(int i = 0;i<arr.length;i++){ if(max<arr[i]){ max = arr[i]; } } return max; } /
