Bass Enhancement iBass Enhancement controls the low-frequency foundation. Sub-Bass (20-60 Hz) adds physical "feeling" — what you feel in your chest at a concert. Bass Boost (60-120 Hz) adds audible weight and warmth. Harmonic Exciter generates upper harmonics so bass is perceived even on small speakers and earbuds that can't reproduce sub-bass. Auto-Enhance analyzes your track and sets optimal levels automatically.
