Flash/Flex 中麦克风对象的增益和活动级别之间的相关性
麦克风的增益属性默认为 50，范围从 0 到 100，它增强来自麦克风的信号。
麦克风 ActivityLevel 属性的范围也是从 0 到 100，并描述录制的麦克风音频的音量。
我需要知道增强信号和活动水平之间的相关性，我已经测试过这确实会相互影响。收益100意味着什么？
The microphone's gain property is default at 50 and ranges from 0 to 100, It boosts the signal from the microphone.
The microphone activityLevel property also ranges from 0 to 100, and describes the volume of the recorded mic audio.
I need to know the correlation between boosting the signal and the activity level, which does have an effect on each other that I have tested. What does a gain of 100 mean?

activityLevel 属性定义麦克风的灵敏度 - 它将拾取的声音范围 - 如果您希望它拾取所有可能的声音，包括背景噪音和安静的噪音，请将此属性指定为 100。如果您希望它仅拾取大声的噪音，请将其设置为0.
增益为麦克风声音放大的强度 - 100 是最大，0 是最小。调高增益会使音质变差（取决于设备的质量），同时声音会变大。
将增益设置为 100 并将活动级别设置为 0 意味着您正在发出更大的噪音。增益 0，
activityLevel100 表示您拾取每个声音而不放大它。The activityLevel property defines the sensitivity of the microphone - the range of sounds it will pick up - if you want it picking up everything it can, including background noise and quiet noises, assign this property to 100. If you want it picking up only LOUD noises, turn it to 0.
The gain is the strength of the amplification of the microphone's sound - 100 is the most, 0 is the least. Turning the gain up makes sound quality deteriorate (Depending on quality of equipment), while it gets louder.
Turning gain to 100 and activityLevel 0 means you're making Loud noises louder. Gain 0,
activityLevel100 means you're picking up every sound and not amplifying it.
