FilterFreak

This is the secret weapon for a lot of engineers who know how to properly increase depth within their tracks. Not only is this an effect filter... it is a mix changer. Put in on any mono or stereo audio track you desire to improve. By understanding how to set the envelope follower you can easily add realism and movement into all your tracks building a more solid as well as transparent feel. This is a necessity if you are having trouble getting tracks to pop out in pleasing way. It can end struggles. I've been using it since it came out and wouldn't mix without it. You must use it with the mix levels set to the low side to really see what it can do. Check it out.
