Audio drop outs during live recording

Hi

My app allows users to record video and audio via their webcams.  If the user stops speaking for more than a second or two there seems to be an interruption to the recording....so when they start speaking again the first second (or so) of their audio doesn't get captured.  It's almost like Flash falls asleep when there's no voice input and then wakes up slightly too late to start recording again.

Ordinarily this wouldn't be an issue but my users want their recordings to be faultless and so aren't prepared to use the service unless every syllable gets recorded.

Any ideas on how to fix this would be greatly appreciated!
