Warren, I think the weird speed up sound you are hearing is a setting within Realband that drove me nuts for a couple of days before I figured out what it was.

To get rid of this annoying sound when rendering: Click on options, preferences, then select the Audio tab. Click on the 'Drivers' button on the Audio tab. Uncheck 'Output always on' box. This box was always unchecked until a few versions ago when they made it checked by default.
