Detect activity level of microphone in flex

Question

Hi,

I have to detect avtivityLevel of microphone in Flex. I am using the activityLevel property of Microphone class but as I found out it always return -1 even if I have done Microphone.getMicrophone(). To detect activity level we have to set microphone.setLoopback = true;

Does anybody know how to do this without using loop back as I do not want to hear my sound back just monitor the activity level

Thanks

The microphone won't show any activity until it is attached to a NetStream connection. You can use a MockNetStream to fake the connection using OSMF - see my answer here.
