不废话，上代码。

public class RaiseVolumeUtil {
  
  public static String raiseByRatio(String audioPath, String outputDir, float ratio)
      throws Exception {
    List paths = Splitter.on(".").splitToList(audioPath);
    String ext = paths.get(paths.size() - 1);
    if (!Arrays.asList("wav", "mp3").contains(ext)) {

    }
    String resultPath =

    String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);
    ProcessBuilder builder =

            "-filter:a",
            MessageFormat.format("volume={0}", String.valueOf(ratio)),
            resultPath);
    builder.inheritIO().start().waitFor();
    return resultPath;
  }

  
  public static String raiseByDecibel(String audioPath, String outputDir, int decibel)
      throws Exception {

    String resultPath =

            resultPath);
    builder.inheritIO().start().waitFor();
    return resultPath;
  }

}

代码说明

1、raiseByRatio和raiseByDecibel两个方法分别是按照音量倍率提升和按照分贝数提升音频，参数均为音频地址、输出目录、倍率（分贝数）。

2、倍率参数为浮点型，分贝参数为int类型。

3、音频后缀校验只有两种，如需添加，可以自行添加。

4、文件名避免重复使用uuid。

验证一下

提供一个查看音频分辨率的命令，命令如下：

ffmpeg -i C:UsersyiDesktop660952057553105332.wav -filter_complex volumedetect -c:v copy -f null C:UsersyiDesktop1.txt

原始音频音量

验证代码

  public static void main(String[] args) throws Exception {
    System.out.println(
        raiseByRatio("C:/Users/yi/Desktop/660952057553105332.wav", "C:/Users/yi/Desktop/", 2.5f));
    System.out.println(
        raiseByDecibel("C:/Users/yi/Desktop/660952057553105332.wav", "C:/Users/yi/Desktop/", 30));
  }
