Hello,

I'm using PortAudio to record audio signals. In my project, I need to know
the exact time when computer begins to record. Would you please tell me
when the recordCallback function is involved and when the first frame of
data enters the input buffer? Is there an API that can return the computer
time when microphone begins to record?

Thanks so much!
