前言

遇到解析微信的 语音文件 需要将amr格式转换为mp3格式
然后搜了一下 基本上就是基于ffmpeg来处理就行
这里记录一下 方便自己速查

示例

ffmpeg
1
ffmpeg  -i  xxx.amr  -vn  -acodec  libmp3lame  -f  mp3  -y  xxx.mp3
it.sauronsoftware.jave

使用jave 参考:https://developer.aliyun.com/ask/77316?spm=a2c6h.13159736

        }  
    }  
}
dadiyang.jave

使用dadiyang 1.0.6的依赖有点问题 降级1.0.5 即可

package com.ming.service;

import it.sauronsoftware.jave.AudioUtils;

import java.io.File;

public class AudioUtilsTest {
    public static void main(String[] args) {
        File source = new File("测试语音文件.amr");
        File target = new File("testAudio.mp3");
        AudioUtils.amrToMp3(source, target);
    }
}

总结

都是ffmpeg 处理的
看看ffmpeg 然后借助一些封装的jar使用就行
核心还是ffmpeg
