iLounge recently reviewed the Bonjiovi DPS app, and gave it a positive review (B-), so figured I would check it out (esp. being free). I agree that the app improves iOS sound quality, at least coming out of my iPad (due to Digital Power Station's real-time audio re-mastering), but maybe not enough really to make me give up the built-in player apps. In other "what I played" news, Paper Racer and Jet Car Stunts are still my picks for casual game time. Read on for my review of the free DPS app.
Nothing mind-blowing about the interface, but at least a common theme was adhered to, I guess (icons like the iOS home screen). The DPS app let's you play internal non-DRM protected music, videos, and podcasts, and also access your playlists (or add new ones), pretty much like the internal iPod apps do, except you can apply DPS enhancement to the sound. DPS technology is included in the new wireless iP1 docks from iHome (search our blog for "iHome CES" for more info). Unfortunately, no integration exists for YouTube or 3rd-party apps. The DPS settings are only applied when playing from inside the Bonjiovi app.
A few settings are available for selecting profiles, which are settings for different output devices (headphones, speaker, dock). My understanding is that the engineers at DPS are attempting to create unique sound profiles for several devices. There are some free ones included in the app, but I didn't notice a great deal of difference and finally settled on "Toledo" for my dock. There are several additional paid profiles for popular headphone brands listed, but the only free ones are for Apple's ear buds.
I tested the sound output from my iPad, through my Stem speaker dock, and using both internal player, and another sound processing app that works with the dock. I also tested using a pair of third-party headphones. The sound difference produced by selecting and de-selecting the "B" icon (see above), which activates the DPS processing, is notable. A richer, and somewhat boosted overall sound, but the stem:connect app (see my recent review
), with it's Sonic iQ boost and equalization, was about the same (also a free app), but you can't play videos with it and the EQ settings only work when docked. The DPS app also has much better player controls, though they are still not as effective as the built-in apps. Still, if you are looking to give your iOS sound a bit of a shot in the arm, you might want to check it out. You can grab Bonjiovi DPS here
