IRON MAIDEN , who have sold over 90 million albums and performed over 2,000 live concerts across the globe in their career to date, are now offering their fans the opportunity to get one more step closer to listening to their music as they want it to be heard. Introducing Maiden Audio App, a collaboration with Onkyo’s HF Player App, tuned for IRON MAIDEN.

Preloaded EQs tuned by all six members of IRON MAIDEN (Bruce Dickinson, Dave Murray, Adrian Smith , Janick Gers , Steve Harris, Nicko McBrain) give you the sound of IRON MAIDEN as each member intends you to hear it.

The touch-adjustable linear-phase FIR equalizer offers 16,384 discrete bands of high-definition equalization with zero loss in audio quality.
Besides using the IRON MAIDEN Member’s EQ, you can also name and save your own custom EQ presets.

You have the opportunity to upgrade the Maiden Audio app to include Hi-Res 192 kHz/24-bit playback. Just ADD the HD pack, then you can take your Hi-Res albums on the road with full support for FLAC, WAV, and DSD on the iPhone, iPod touch, and iPad.

Great sound, needs work


This is a great sounding app. Very dynamic audio and the Maiden presets are a good start to custom settings. I have two problems: on HD albums with multidiscs, the song order is wrong. It lists Disc 1, song 1, Disc 2 song 1, Disc 1 song 2, Disc 2 song 2, etc. Back and forth between the two discs. This is maddening. My other objection is that the artwork isn’t showing for over half my albums. The artwork is in the metadata (confirmed on two different software) but not showing on my iPhone 6 plus. Minor gripes for a first version of a great sounding app. I hope future updates fix these, because otherwise I’d give it a 5.

Music plays slow


I really liked the idea of this app as i used the main Onkyo app that this one is based on but this had Eddie... I have went back and forth with using it as it seemed like the songs were playing slow on iPhone 6s. I finally verified it today. For a 3:30 minute mp3 file, this app played 3:50 for the song. I used a stopwatch and could be off fractions of a second but not 20 sec. I deleted it and went back to the main Onkyo app. Mind you i am streaming bluetooth to headphone but the Maiden Audio app and the Onkyo app to the same headset still have that time disparity... Has no one else noticed this? I turned off upsampling and everything bit no change

Thank you

Thank you for the app guys. I'm surprised there aren't more reviews. I didn't think an iPhone could get more HD. I wish o could have seen you guys LIVE for the Book of Souls tour. The distance caused me not to go see you, sadly. Keep putting your heart in music, and don't let today's generation get to your head. Stay good!
