DFX Music Player Enhancer Pro (Version 1.30) is a legacy audio enhancement application for Android designed to significantly improve the sound quality of MP3 files. Developed by FxSound.com
Modern DFX versions (now known as "FxSound Enhancer") require a yearly subscription and an always-on internet connection for licensing. Version 1.30.7 uses a classic offline serial key system. Once activated, it runs locally forever, without phoning home or tracking your listening habits.
