I hear something. The part that is supposed to be "not speaking to". It sounds like a squeaking reel on a cheap casette tape with a lot of static. Doesn't sound like conversation, doesn't sound like John, doesn't sound like a human being. No Burke.

For what it's worth, I believe that if the phone had been off the hook there would be no need to enhance the tape...whatever was said would have been audible. And, if Burke had testified that he had been downstairs talking to his parents we would have heard about that incessantly.
