+> 原库地址：https://github.com/GavinCT/AndroidMP3Recorder
+>
+> 更改项：
+>
+> 1. 删除 support 库。
+> 2. compileVersion & targetVersion 从 23 升到 34。
+> 3. minSdvVersion 从 9 升到 20。
+> 4. 删除 mips、x86 等 so，仅保留 arm 系列。
+>
+> 使用方式：
+>
+> 1. 打开 [Releases](https://github.com/yibaoshan/AndroidMP3Recorder/releases) 页面，下载 AAR 包（com.czt.mp3recorder-library-1.0.5.aar）。
+> 2. 把 AAR 包保存到模块的 libs 目录下，然后在 build.gradle 指定依赖。
+>
+> ```
+> dependencies {
+> 
+>     implementation fileTree(dir: 'libs', include: ['*.jar'])
+>     implementation files('libs/com.czt.mp3recorder-library-1.0.5.aar')
