播放WAV文件落后 [英] Play WAV file backward

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 !!!!!!!!

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;

/**

 */
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--;
 }
