【Qualcomm高通音频】当内部Codec和外部Codec上都有麦克风输入，如何做到灵活切换内部外部Codec上的麦克风进行录音呢？
2024-05-13 13:28:35
最近遇到一个项目，既用到高通PMU芯片内置的Codec接了麦克风，也通过外部I2S总线外接了两个麦克风。
详细沟通后，了解到，在普通录音的使用场景中，客户要求可以通过安卓原生api任意切换内部Codec和外部Codec上的麦克风进行录音。
设计思路：
(1)仿照audio-record这个usecase去新增一个usecase，对应外部Codec
(2)找到内部外部Codec区分点
packages/apps/SoundRecorder/src/com/android/soundrecorder/SoundRecorder.javaif (AUDIO_AMR.equals(mRequestedType)) {mRemainingTimeCalculator.setBitRate(BITRATE_AMR);mRecorder.setChannels(1);mRecorder.setSamplingRate(SAMPLERATE_8000);mRecorder.startRecording(MediaRecorder.OutputFormat.RAW_AMR, ".amr", this, audioSourceType, MediaRecorder.AudioEncoder.AMR_NB);
};
从上述代码段API中找到以下几个区分点
1. 采样率
2.码率
3. 声道数量
4. AudioSourceType
实测下来，只有通过AudioSourceType具有实操性。
以下是完整的验证代码diff文件，自测实现内部外部Codec上麦克风切换设计。
不过mixer_path.xml文件，只是调试时使用的开发板,是不带外部Codec的，这个并不影响该功能开发。
重点关注usecase的切换即可。
