Studio Sound essentially destroys audio sound effects and especially music. The easiest solution would be if users could apply studio sound to individual audio tracks. This would be the most logical implementation of this feature in my mind. For example, one user has pristine sound, whereas the other does not. Therefore, you would want to apply the effect to the audio that needs it. While Studio Sound has proven it is an excellent effect, it is not always appropriate for ALL audio within a project. Dialing in the 'amount' doesn't always fix the issue either.
Please make Studio Sound a discrete effect on a track-by-track or file basis.
