Abstract

The invention provides a method and an audio system for realizing multi-channel recording based on an Android system, which are applicable to an audio system of an intelligent device based on an Android system. The audio system sequentially includes a recording application module, an audio framework module, an audio library, and hardware The audio driver module in the abstract module and the kernel includes the following steps: the hardware abstract module calls an audio recording interface for the audio framework to perform multi-channel recording operations through the audio interface; the audio framework module is configured so that the audio framework The module supports multi-channel recording function; configure the recording application module so that the recording application module supports the transmission of multi-channel recording parameters. The beneficial effect of the technical solution is that it can satisfy users to realize the function of multi-channel recording in the Android system, and overcome the problems in the prior art that smart devices based on the Android system, such as mobile phones and tablet computers, only support single-channel or dual-channel recording. Functional Defects.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for realizing multi-channel recording based on an Android system and an audio system. Background technique [0002] Existing android (a kind of free and open-source operating system based on Linux, Android system) system usually provides a recording function, and when performing a recording operation, the recording is performed by calling the android standard interface Audio Record. At the same time, the Android system provides related programs to realize the recording function. The android system is mainly used in mobile terminals such as mobile phones and tablet computers, and the mobile phone mainly has 1 or 2 microphones, so the recording function only supports mono and 2 channels, and does not support more than 2 channels. However, it is a technical problem that needs to be solved at present for the recording function that needs to be realized in multi-chann...
