Description

technical field

[0001] The invention belongs to the technical field of development of mobile applications running on desktop operating systems, and particularly relates to a low-delay audio output method for Android applications on a Linux platform. Background technique

[0002] Audio data processing is a very important part of the Android system. It is responsible for the collection and output of audio data, the control of audio streams, the management of audio devices, and volume adjustment. It mainly includes the Audio Application Framework and the Audio Native Framework. Framework), Audio Services (Audio Services) and Audio Hardware Abstraction Layer (Audio HAL). In addition, MultiMedia is strongly related to audio data processing. MultiMedia is responsible for the encoding and decoding of audio and video. MultiMedia outputs the decoded data through AudioTrack, and the recording data collected by AudioRecord is handed over to MultiMedia for encoding.

[0003] In general...
