RecordMixMp3(带非录制mp3与mp3混音).zip

RecordMixMp3(录音mp3).rar
        ↓相同↑
RecordMixMp3 文件夹是 RecordMixMp3（密码ting@123）.zip 解压后的文件

思路：

解码MP3背景音——》PCM音频源
          	       ↓混合
           	录制PCM音频源
               	       ↓
             	  得到结果PCM
               	       ↓
               	    转码MP3
	      最终得到混音后的文件

音频文件放到SDCard/RecordMixMp3/music目录下
