我是靠谱客的博主矮小台灯，最近开发中收集的这篇文章主要介绍Java 工具类实现音频音量提升，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

前言

本文提供将音频提升音量的java工具类代码，一如既往的实用主义分享。

Maven依赖

不废话，上代码。

    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));
  }
