1. 使用AudioRecord进行录音
2. 实现pcm、wav、mp3音频的录制
3. 实时获取录音的音量、及录音byte数据
4. 获取wav/mp3录音文件的时长
5. 可配置录音的采样率、位宽 (v1.04更新)
6. 录音可视化 (v1.05更新)

1. 初始化

• init

  /**
  * 参数1: Application 实例
  * 参数2: 是否打印日志 
  */
  RecordManager.getInstance().init(MyApp.getInstance(), false);

• 在清单文件中注册Services

  <service android:name="com.zlw.main.recorderlib.recorder.RecordService" />

• 确保有录音权限

2. 配置录音参数

• 修改录音格式(默认:WAV)

   RecordManager.getInstance().changeFormat(RecordConfig.RecordFormat.WAV);

• 修改录音配置

   RecordManager.getInstance().changeRecordConfig(recordManager.getRecordConfig().setSampleRate(16000));
   RecordManager.getInstance().changeRecordConfig(recordManager.getRecordConfig().setEncodingConfig(AudioFormat.ENCODING_PCM_8BIT));

• 修改录音文件存放位置(默认sdcard/Record)

   RecordManager.getInstance().changeRecordDir(recordDir);

• 录音状态监听

  RecordManager.getInstance().setRecordStateListener(new RecordStateListener() {
   @Override
   public void onStateChange(RecordHelper.RecordState state) {
   }
   }
   @Override
   public void onError(String error) {
   }
  });

• 录音结果监听

  RecordManager.getInstance().setRecordResultListener(new RecordResultListener() {
   @Override
   public void onResult(File result) {
   }
  });

• 声音大小监听

   RecordManager.getInstance().setRecordSoundSizeListener(new RecordSoundSizeListener() {
   @Override
   public void onSoundSize(int soundSize) {
   }
  });

• 音频数据监听

   recordManager.setRecordDataListener(new RecordDataListener() {
   @Override
   public void onData(byte[] data) {
   }
   });

• 音频可视化数据监听

   recordManager.setRecordFftDataListener(new RecordFftDataListener() {
   @Override
   public void onFftData(byte[] data) {
   audioView.setWaveData(data);
   }
   });

3. 录音控制

• 开始录音

  RecordManager.getInstance().start();

• 暂停录音

  RecordManager.getInstance().pasue();

• 恢复录音

  RecordManager.getInstance().resume();

• 停止

  RecordManager.getInstance().stop();
