如何在Java中淡出一个.wav文件？

import javax.sound.sampled.*;

String filePath = "your_file_path.wav";
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(filePath));

AudioFormat audioFormat = audioInputStream.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, audioFormat);
Clip clip = (Clip) AudioSystem.getLine(info);

clip.open(audioInputStream);
clip.start();

FloatControl gainControl = (FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN);
float volume = 1.0f; // 初始音量
float decreaseAmount = 0.01f; // 减小的音量
while (volume > 0) {
    volume -= decreaseAmount;
    if (volume < 0) {
        volume = 0;
    }
    float dB = (float) (Math.log(volume) / Math.log(10.0) * 20.0);
    gainControl.setValue(dB);
    try {
        Thread.sleep(10);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

import javax.sound.sampled.*;
import java.io.File;

public class FadeOutWav {
    public static void main(String[] args) {
        try {
            // 加载.wav文件并创建AudioInputStream对象
            String filePath = "your_file_path.wav";
            AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(filePath));

            // 获取音频格式并创建Clip对象

            // 打开Clip并开始读取音频数据
            clip.open(audioInputStream);
            clip.start();

            // 循环逐渐减小音量实现淡出效果
            FloatControl gainControl = (FloatControl) clip.getControl(FloatControl.Type.MASTER_GAIN);

                }
            }

            // 关闭Clip和AudioInputStream
            clip.stop();
