I have a good, clean .wav audio file which I imported into PR6.5 for a video clip. After rendering the audio and playback it sounds like an old record album with scratches. I exported the clip and the scratch sounds were exported with it. Anybody had this experience? What's the best remedy?

Check the audio levels in the audio mixer, they shoul not reach red.

Audio levels checked, did some adjustments and got better results. Maybe I need to do more adjustments. Thanks Ann.
