Title: DUAL MICROPHONE SWITCHING METHOD AND APPARATUS
Abstract:
A dual microphone switching method and apparatus. The method comprises: reading a switching parameter from a memory variable of a hardware abstraction layer (HAL), the switching parameter indicating a main microphone and an auxiliary microphone in two microphones (S201); and invoking a function of the HAL to configure the switching parameter to the two microphones and a corresponding codec by means of a Kernel layer (S202). The method can implement switching between a main microphone and an auxiliary microphone in two microphones, thereby solving the problem of sound-reception quality reduction caused by fixed configuration of the main microphone and the auxiliary microphone.
