安卓AudioRecord实现录音和播放,可以暂停和获取声音的大小,格式为amr和wav,可以对音频进行加密

最近项目要求做一个录音功能,要可以暂停的,然后对音频进行加密解密,还要根据声音大小做一个自定义的柱形图,废话不多说,下面进行录音功能实现:

项目大概长这样:

 

安卓AudioRecord实现录音和播放,可以暂停和获取声音的大小,格式为amr和wav,可以对音频进行加密_第1张图片

设计的思路:
由于自带的AudioRecord没有pauseRecord()方法,我把开始录音-->(暂停/继续录音)...-->停止录音叫做一次录音,点击一次暂停就会产生一个文件(.pcm),再点击的时候对文件进行继续写入。

 

对类的说明:

  1. AudioRecorder:封装了录音的方法:创建录音对象、开始、暂停、停止、取消,使用静态枚举类Status来记录录音的状态。
  2. AudioFileUtils:文件工具类,用于文件路径的获取
  3. AudioEncoder:对文件进行转码的父类,采用mvp模式,具体实现看子类的
  4. AmrEncoder:继承AudioEncoder,实现父类的转码方法,amr格式。
  5. WavEncoder:继承AudioEncoder,实现父类的转码方法,wav格式。
  6. WaveHeader: wav文件头
  7. onVoluneListener:监听录音分贝大小,用于拓展业务的处理。
  8. RecordService:将录音功能集成封装在服务里面,暴露几个方法调用的接口
  9. AESUtils:用aes对音频文件进行加解密,提高用户信息的安全性。
