代码

不废话，上代码。

packagecom.huyi.csdn.tools;importcn.hutool.core.util.IdUtil;importcom.google.common.base.Joiner;importcom.google.common.base.Splitter;importorg.bytedeco.javacpp.Loader;importjava.io.File;importjava.text.MessageFormat;importjava.util.Arrays;importjava.util.List;/***@Program:csdn@ClassName:RaiseVolumeUtil@Author:剑客阿良_ALiang@Date:2021-11-2500:42@Description:*提升音量工具@Version:V1.0*/publicclassRaiseVolumeUtil{/***通过倍率提升音量**@paramaudioPath音频地址*@paramoutputDir输出目录*@return图片地址*@throwsException异常*/publicstaticStringraiseByRatio(StringaudioPath,StringoutputDir,floatratio)throwsException{List<String>paths=Splitter.on(".").splitToList(audioPath);Stringext=paths.get(paths.size()-1);if(!Arrays.asList("wav","mp3").contains(ext)){thrownewException("formaterror");}StringresultPath=Joiner.on(File.separator).join(Arrays.asList(outputDir,IdUtil.simpleUUID()+"."+ext));Stringffmpeg=Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);ProcessBuilderbuilder=newProcessBuilder(ffmpeg,"-i",audioPath,"-filter:a",MessageFormat.format("volume={0}",String.valueOf(ratio)),resultPath);builder.inheritIO().start().waitFor();returnresultPath;}/***通过分贝提升音量**@paramaudioPath音频地址*@paramoutputDir输出目录*@return图片地址*@throwsException异常*/publicstaticStringraiseByDecibel(StringaudioPath,StringoutputDir,intdecibel)throwsException{List<String>paths=Splitter.on(".").splitToList(audioPath);Stringext=paths.get(paths.size()-1);if(!Arrays.asList("wav","mp3").contains(ext)){thrownewException("formaterror");}StringresultPath=Joiner.on(File.separator).join(Arrays.asList(outputDir,IdUtil.simpleUUID()+"."+ext));Stringffmpeg=Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);ProcessBuilderbuilder=newProcessBuilder(ffmpeg,"-i",audioPath,"-filter:a",MessageFormat.format("volume={0}dB",String.valueOf(decibel)),resultPath);builder.inheritIO().start().waitFor();returnresultPath;}}

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-iC:\Users\yi\Desktop\660952057553105332.wav-filter_complexvolumedetect-c:vcopy-fnullC:\Users\yi\Desktop\1.txt

原始音频音量

验证代码

publicstaticvoidmain(String[]args)throwsException{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
