Native framework code is located inīinder IPC proxies facilitate communication over process boundaries. The native framework provides a native equivalent to the dia package, calling Binder IPC proxies to access the audio-specific services of the media server.
The JNI code associated with dia calls lower level native code to access audio hardware. For example, media player application, voice recorder application, SIP call application etc are the applications which are going to use audio hardware. The application framework includes the app code, which uses the dia APIs to interact with audio hardware. Audio ArchitectureĪndroid audio architecture defines how audio functionality is implemented and points to the relevant source code involved in the implementation.

These concepts are very much useful when you working on Audio HAL for different hardware devices such HDMI audio, Bluetooth SCO audio devices etc. Period size: This is the size of each period in Hz. Period: Period is the time interval between each processing frames to the hardware. PCM sound consists of a flow of sound frames.ĭata rate: Date rate is the number of bytes, which must be recorded or provided per second at a given frame size and rate. Sample Rate or simply “Rate” is defined as the number of samples per second. For example,in mono, the frame size is one byte (8 bits ). This too vary based on number of channels. Whereas in stereo(2 channel), each frame consists of two samples.įrame size: Frame size is the size in bytes of each frame. In case of mono channel sound, a frame is consists of single sample.

The audio architecture in android has to take care of many aspects such as supporting more hardware such as HDMI, earpiece, headset, speaker, mic, Bluetooth SCO, A2DP ectc, relat-time requirements and supporting different software like media player/recoder, VIOP application, SIP application and phone calls. In general, it is Audio signal processing which involves lot of operations and provide various functionalities such as playing music, recording microphone audio,real-time voice communication, adding audio effects such as echo cancellation, noise suppression etc. This article highlights Android audio architecture, audio frameworks, role of audioflinger, audio HAL and its implementation details.
