Android Audio是指Android操作系统中的音频系统。它提供了一组API,允许应用程序录制音频、播放音频以及对音频数据进行处理。 Android音频系统还提供了一些音频效果和音频处理功能,例如均衡器、混响和自动增益控制等。
在Android中,音频通道和音频流分别被称为音频路由和音频源。音频路由指的是音频数据的物理路径,例如耳机、扬声器、Bluetooth耳机等。音频源指的是音频数据的来源,例如麦克风、音乐文件等。
使用Android音频API,您可以完成以下操作:
- 播放音频
- 录制音频
- 处理音频数据
- 实现音频效果
- 控制音频路由
- 管理音频焦点
Android音频API提供了许多类和接口,包括MediaPlayer、AudioRecord、AudioTrack、AudioManager等。您可以使用它们来实现各种音频功能和效果。

Android Audio是Android系统中用于音频管理的模块。它的客户端是AudioTrack,而AudioFlinger则是Android系统中音频管理的中枢。所有的音频接口设备都保存在AudioFlinger的成员变量mAudioHwDevs中。不同的Android产品在音频的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。在Android系统中,音频配置文件存放的路径有两处,具体路径可以从AudioPolicyManagerBase.cpp文件中获取。
