试图扭曲Java中的音频

Question

我找到了一个名为JVST的库，可以加载VST文件并相应地过滤音频。问题是，我不知道如何使用它。我所能做的只是从网站上复制和粘贴示例代码，并根据需要进行调整，但仍然无法正常工作。我想要做的是扭曲用户选择模拟扬声器的.au或.wav文件的音频。我不确定多频段压缩是否是最好的使用方式，但是我会尝试一下，如果失败了，我可以使用一大堆自定义VST插件。不管怎么说，这里是代码：

import sun.audio.*; //import the sun.audio package 
import java.awt.*; 
import java.io.*; 
import org.boris.jvst.*; 
@SuppressWarnings("serial") 
public class SoundPlayer extends Frame implements FilenameFilter { 
Button openButton = new Button("Open"); 
Button playButton = new Button("Play"); 
Button loopButton = new Button("Loop"); 
Button stopButton = new Button("Stop"); 
Label filename = new Label("     "); 
File theFile = null; 
@SuppressWarnings({ "restriction" }) 
AudioData theData = null; 
InputStream nowPlaying = null; 

@SuppressWarnings({ "deprecation" }) 
public SoundPlayer() { 
    super("Boombox"); 
    resize(300, 200); 
    Panel north = new Panel(); 
    north.setLayout(new FlowLayout(FlowLayout.LEFT)); 
    north.add(new Label("File: ")); 
    north.add("North", filename); 
    add("North", north); 
    Panel south = new Panel(); 
    south.add(openButton); 
    south.add(playButton); 
    south.add(loopButton); 
    south.add(stopButton); 
    add("South", south); 
} 

@SuppressWarnings("deprecation") 
public static void main(String[] args) { 
    SoundPlayer sp = new SoundPlayer(); 
    sp.show(); 
} 

@SuppressWarnings({ "deprecation", "restriction" }) 
public void open() { 
    FileDialog fd = new FileDialog(this, "Please select a .au or .wav file:"); 
    fd.setFilenameFilter(this); 
    fd.show(); 
    try { 
     theFile = new File(fd.getDirectory() + "/" + fd.getFile()); 
     if (theFile != null) { 
      filename.setText(theFile.getName()); 
      FileInputStream fis = new FileInputStream(theFile); 
      AudioStream as = new AudioStream(fis); 
      theData = as.getData(); 
     } 
    } 
    catch (IOException e) { 
     System.err.println(e); 
    } 
} 

@SuppressWarnings("restriction") 
public void play() { 
    stop();  
    if (theData == null) open(); 
    if (theData != null) { 
     AudioDataStream ads = new AudioDataStream(theData); 
     AudioPlayer.player.start(ads); 
     nowPlaying = ads; 
    } 
} 

@SuppressWarnings("restriction") 
public void stop() { 
    if (nowPlaying != null) { 
     AudioPlayer.player.stop(nowPlaying); 
     nowPlaying = null; 
    } 
} 

@SuppressWarnings("restriction") 
public void loop() { 
    stop(); 
    if (theData == null) open(); 
    if (theData != null) { 
     ContinuousAudioDataStream cads = new ContinuousAudioDataStream(theData); 
     AudioPlayer.player.start(cads); 
     nowPlaying = cads; 
    } 
} 

public boolean action(Event e, Object what) { 

    if (e.target == playButton) { 
     play(); 
     return true; 
    } 
    else if (e.target == openButton) { 
     open(); 
     return true; 
    } 
    else if (e.target == loopButton) { 
     loop(); 
     return true; 
    } 
    else if (e.target == stopButton) { 
     stop(); 
     return true; 
    } 

    return false; 

} 

public boolean accept(File dir, String name) { 

    name = name.toLowerCase(); 
    if (name.endsWith(".au")) return true; 
    if (name.endsWith(".wav")) return true; 
    return false; 
    public static void main(String[] args); throws Exception { 
     AEffect a = VST.load("C:/Program Files (x86)/Audacity 1.3 Beta (Unicode)/Plug-Ins/mda MultiBand.dll"); 
     a.open(); 
     a.setSampleRate(44100.0f); 
     a.setBlockSize(512); 

     // attempt some processing 
     int blocksize = 512; 
     float[][] inputs = new float[a.numInputs][]; 
     for (int i = 0; i < a.numInputs; i++) { 
      inputs[i] = new float[blocksize]; 
      for (int j = 0; j < blocksize; j++) 
       inputs[i][j] = (float) Math 
       .sin(j * Math.PI * 2 * 440/44100.0); 
     } 
     float[][] outputs = new float[a.numOutputs][]; 
     for (int i = 0; i < a.numOutputs; i++) { 
      outputs[i] = new float[blocksize]; 
      for (int j = 0; j < blocksize; j++) 
       outputs[i][j] = 0; 
     } 

     a.processReplacing(inputs, outputs, blocksize); 

     VST.dispose(a); 
    } 
} 
} 

编辑 它给人的错误是：

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

    at SoundPlayer.main(SoundPlayer.java:35)

我进口JVST JAR到我的构建路径，瞧！进口org.boris.jvst。*;工作
