+目前谷歌只开放了Android10及以上系统同步音频内录功能
 10之前录音的时候会截取原本系统的音频输出
 即 开启内录时候无法在手机上正常使用耳机扬声器输出
+且普通应用的声音默认不会被捕获
+
+**安卓10音频输入原理**
+- 音频权限相当于是MediaProjection的附属产物
+- 只有在成功获取MediaProjection，开启了ForegroundService才能使用
+- 相比于AudioRecord普通用法使用，将setAudioSource改为setAudioPlaybackCaptureConfig，这里的AudioPlaybackCaptureConfiguration的构建需要使用到之前成功获取的MediaProjection
+<br>
+- **一些注意事项**
+  - 使用AudioFormat.ENCODING_PCM_FLOAT，数值范围[-1,1]的32位浮点数据，对应了rust端opus编码器的输入格式。
+  - libopus库中使用的opus_encode_float，对于输入的音频数据长度有一定要求，安卓端输出的包过大需要分批发送
