播放WAV文件落后

本文介绍了播放WAV文件落后的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我做的编织在Java中。如果你后退的时候，声音反向播放。如何向后播放WAV文件？也许用类似 previous流（）？辫的网站，你可以明白我的意思。

I'm making Braid in Java. If you rewind the time, the sound plays backward. How to play a WAV file backwards? Maybe with a stream with something like previous()? On the site of Braid can you see what I mean.

YEEEEEEESSSSS!!!!!!!!

我解决了我自己（14岁！）结果我写这个类：

I solved it by myself (14 years old!!) I've written this class:

import java.io.IOException; import javax.sound.sampled.AudioInputStream; /** * * @author Martijn */ public class FrameBuffer { private byte[][] frames; private int frameSize; public FrameBuffer(AudioInputStream stream) throws IOException { readFrames(stream); } public byte[] getFrame(int i) { return frames[i]; } public int numberFrames() { return frames.length; } public int frameSize() { return frameSize; } private void readFrames(AudioInputStream stream) throws IOException { frameSize = stream.getFormat().getFrameSize(); frames = new byte[stream.available() / frameSize][frameSize]; int i = 0; for (; i < frames.length; i++) { byte[] frame = new byte[frameSize]; int numBytes = stream.read(frame, 0, frameSize); if (numBytes == -1) { break; } frames[i] = frame; } System.out.println("FrameSize = " + frameSize); System.out.println("Number frames = " + frames.length); System.out.println("Number frames read = " + i); } }

和则：

FrameBuffer frameStream = new FrameBuffer(austream); //austream is the audiostream int frame = frameStream.numberFrames() - 1; while (frame >= 0) { auline.write(frameStream.getFrame(frame), 0, frameStream.frameSize()); frame--; }
