This isn’t just a graphic eq, it’s a pretty good player too! Much better than itunes, tho that’s not saying much. Demon is great because of that AND because it’s free! It lets you own your own music too (unlike iTunes). It lets you tune it to your liking without having to fiddle through substandard presets, and it works well with pc apps. The only thing that needs improvement is once in a while the app cuts off the song you’re listening to right in the middle and goes to the next one. They could also work on song fading; out at the end of the current one and into the beginning of the next one with a slight overlap, the way MediaMonkey does. Otherwise, great app! Thanks!

Just awesome!

Now approaching iOS 15, all I can say is that I continue to be very grateful to the developers behind this app. If you have any type of hearing loss or abnormality, you need to start listening to your audio through this app. If you’re blessed with great hearing, this is the best app for correcting audio engineers’ biases. I just installed the 64-bit version via the App Store. It's a great day. 😁 No, really, thank you to the Denon team. I have been using this app almost daily for several years now. It's tied as my favorite app with two, maybe three other apps. My only complaint is that sometimes, rarely, I have to shut it down completely (tap home button twice and swipe up) to get it to play clearly again. For what you get by having this app, a totally acceptable quirk. I was honestly afraid that Denon was abandoning this app and that, when iOS 11 was pushed, it would be obsolete. There is no substitute for this app. All the professional reviewers say the same, this is the premium EQ app available today.

Does Not Play Anything

I just downloaded this app and bought the $2 EQ function. However, the app does not play anything at all. It seems to find the downloaded music just fine, loads it up into the queue, but then nothing. Pressing play will result in a faint “click” as if it is trying to activate the track, but nothing will play. The play button does not turn into the pause symbol, either. Forward/backward scrubbing through a track seems to work, and it shows track time information, but still there is no audio as the tracks will not play. I have deleted and re-downloaded the app, restarted my phone, started and quit Apple Music so as to make it “let go” of the Airplay function, (A track that is supposed to be playing in the Denon Audio app in Airplay tab simply says “iPhone”), but still nothing. Even tried a few different headphones/earbuds with no luck. There is absolutely no support on this app that I can find outside of the in-app FAQ, which has no troubleshooting.

Can I have my $2 back, please?
