Android audio

Android audio系统中有几个重要的组件和接口。首先，所有的音频接口设备会被保存到AudioFlinger的成员变量mAudioHwDevs中。其次，Android的audio_hw_device接口提供了一组音频硬件操作的函数，而AudioHardwareInterface接口和audio_hw_device接口定义的接口基本一致，这是为了兼容Android先前版本。此外，在Android系统中，不同的产品在音频设计上通常存在差异，这些差异可以通过音频配置文件audio_policy.conf来获得。音频配置文件的存放路径有两处，可以从AudioPolicyManagerBase.cpp文件中获取。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
