Abstract

The invention provides a method for realizing multi-track recording based on an Android system and an audio system. The method is applicable to the audio system of an intelligent device based on the Android system. The audio system sequentially comprises a recording application module, an audio framework module, an audio library, a hardware abstraction module and an audio driving module in a kernel. The method comprises the steps that the hardware abstraction module calls an audio recording interface so that an audio framework can execute multi-track recording operation through the audio interface; the audio framework module is configured to support a multi-track recording function; and the recording application module is configured to support transmission of multi-track recording parameters. The technical scheme has the advantages that the requirement of a user for achieving the multi-track recording function in the Android system can be met, and the defect that in the prior art, theintelligent device, such as a mobile phone and a tablet computer, based on the Android system only supports a single-channel or double-channel recording function is overcome.

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...
