The problem is that if you know EXACTLY what curves were applied originally, AND you know the specific EQ algorithms used, you MAY be able to make some corrections. But, the chances of knowing EXACTLY what curves (freq. center point, filter type, slope, and bandwidth), you can't make those corrections, and are just adding still more processing to the mix. -- --- My bands, CD projects, music, news, and pictures: http://www.lateralforce.com My blog, with commentary on a variety of things, including audio, mixing, equipment, etc, is at: http://audioandmore.wordpress.com Staat heißt das kälteste aller kalten Ungeheuer.
