The S-curve helps minimize distortion in lower frequencies and maintains clean, uncolored high frequencies, especially during fast release times. Operating Modes:

This function creates a three-stage behavior: a slow onset that accelerates toward a midpoint before decelerating at the end. Voxengo Deft Compressor (Win & Mac)

Professional users often cite Deft Compressor as an "underrated" tool that excels in specific mixing scenarios. The S-curve helps minimize distortion in lower frequencies
