Answer 1

The "red banner" indicates that your application is currently using the microphone hardware. It is shown by applications that have active control over the main recording context, and hides when your application releases it's hold on the recording context (such as when the home button is pressed). Because you cannot predict when the home button will be pressed to exit your application, you will need to either support background recording to persist the banner (then gracefully release your context after a second or two to have the status bar animate back to black), or somehow terminate your context before the application closes.
