推荐答案
存在一个误解，即在带有2个麦克风的设备中，以立体声模式录制时将同时使用两个麦克风.
There is a misconception that in devices with 2 microphones, both the microphones will be used when recording in the stereo mode.
以我在数十种设备上进行测试的3年经验，我发现从来没有这样.
In my 3 years experience of testing on tens of devices, I have found that this was never the case.
我单独使用的主麦克风 用于单声道录音和立体声录音，在我使用过的各种Android设备中-从低成本大众模型到旗舰产品
The primary mic alone is used both in mono and stereo recording in the wide range of Android devices that I have worked with - from low-cost mass models to flagships.
这样做的原因之一是，主麦克风比辅助麦克风质量更高(灵敏度更高，噪音更少等)，而且成本更高.
One reason for this is that the primary mic is of a better quality (more sensitive, less noisy, etc.) and costlier than the secondary mic.
