Logic Pro 8 Strange Noise Tone at End of Bounce



When I bounce my song down there is a strange low tone at the quiet ending of my song. Doesn't happen every time. I've tried all kinds of remedies. Not using normalize and adding a EQ at the end have helped but it is often still present. I also added a DC Blocker at the end which also helped a little but it would be nice if it went away. Ideas very very much welcome. If you can please email at: justindr660@hotmail.com
