Here is an excerpt from another source:
Bongiovi DPS improves the clarity of your mobile library across all frequencies and provides cleaner, deeper bass response. You will hear detail that you never heard before. DPS analyzes the audio signal in real-time and optimizes it for playback through any device connected to your headphone, Line-out jacks, or Bluetooth connected speakers. It also compensates for differences in volume between songs and enhances dialogue and sound effects for personal videos and podcasts.
Anyway my first weekend with this app was deemed a success by both me and my better half. The sound quality was clearer, the bass, mids, and highs were better especially at lower volume levels where I was really lacking before. This is where the Wife is especially happy because I don't need to utilize nearly as much volume to bring my music to life as I used too. Now as far as if it helps out the performance with it loud? I haven't got to go there yet, she threatened me with something that sounded like castration it I attempted to play with it any louder.
