Method for multi-channel recording based on android system and audio system

An audio system, applicable to a method for realizing multi-channel recording based on an Android system, which is applicable to an audio system of an intelligent device based on the Android system, wherein the audio system sequentially comprises a recording application module, an audio framework module, an audio library, a hardware abstraction module and an audio driver module in a kernel, wherein the method comprises following steps of:

• Step S1, the hardware abstraction module calling an audio recording interface, so that the audio framework executes a multi-channel recording operation through the audio recording interface;
• Step S2, the audio framework module being configured to support a multi-channel recording function;
• and
• Step S3, the recording application module being configured to support transmission of multi-channel recording parameters;
• wherein the audio framework module comprises a parameter configuration file, wherein in Step S2, a method for configuring the audio framework module comprises following steps of:
• Step S21, adding a multi-channel processing sub-module to the parameter configuration file;
• Step S22, in the configuration file, channel number support parameters being configured to support the multi-channel;
• and
• Step S23, in the configuration file, processing channel number being configured to support processing the multi-channel;
• wherein
• the configured parameter configuration file is available for the audio framework module to support the multi-channel recording operation.
