}

}

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:\Users\yi\Desktop\660952057553105332.wav -filter_complex volumedetect -c:v copy -f null C:\Users\yi\Desktop\1.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));

}

执行结果
