This patch will only affect tire sounds (louder from the in-cockpit view to enable you to judge grip, wheelspin, and overall traction state), as well as the PA announcer and crowd sounds. NOTE that this patch includes a Windows-style installation wizard, so you don't need to place any files in any specific folders or open up Notepad to do any text editing. Also note that this patch is compatible with BOTH the full version and the demo verion of the game -- see the readme file for details.
