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

差不多精准

按照分贝数效果

稍微更准一点。

总结

没啥好总结的。
