Looking for the best listening experience for your iTunes Library? Look no further than LouderLogic – the Advanced Audio Player.

LouderLogic features include:

- 4-band parametric EQ
- Dynamic interactive Play Queues
- Spectrum Animation Mode
- Crossfading
- Professional audio enhancement with patent pending ALX technology

With the McDSP 4-band parametric equalizer, you get the highest quality interactive EQ for your iOS device, along with the ability to customize and tweak to your heart's content. Easily drag the curves to control boost and cut, and use two fingers to adjust the Q (bandwidth).

Play Queues let you modify what's coming up next at any time, without interrupting your current track.

Spectrum Animation Mode lets you view the audio signal being animated right behind the album artwork.

Adjust the crossfade time between songs from 1 to 30 seconds.

LouderLogic brings the fullness you crave out of every song, using patent pending Audio Level eXtension (ALX) technology by McDSP. LouderLogic minimizes volume fluctuations between songs while maximizing all the musical details the artist intended you to enjoy. Simply put, you’ll get more from your music!

“If you don’t have LouderLogic I don’t know why you’re even listening to music.” – Chaka Blackmon, Producer/Songwriter for Christina Aguilera, CeCe Winans, MTV and Disney.

Please note that while LouderLogic does play back DRM protected music, it cannot apply ALX enhancement to DRM protected audio. DRM protected audiobooks are not currently playable. ALX enhancements cannot be applied to music that is still "in the cloud" in iTunes Match, but can be applied once downloaded to your device.

Customer Reviews


i purchased this app a while back and it was phenomenal for listening to all types of music and getting great sound when using high end headphones. as mentioned by others, since the latest update it just does not work at all. very disappointing.

since writing this review i have replaced my ipad air 2 with an ipad pro. i was really looking forward to listening to my music on it but alas, nothing has been done to fix the issues. i check every no and then to see if it has been fixed but still.......each time i check i am sadly disappointed.

A Miracle

Hope they fix this app soon. The others AREN'T EVEN CLOSE. Not only plays songs louder, but has superb equalizer. In sum: MUCH BETTER THAN APPLE'S MUSIC APP. Maybe that's why their system update broke it???? (Apple has been doing so many stupid things lately. Just one example -- of MANY -- who would ever have imagined that people would want LONG lists of albums instead of short lists of songs? Someone need to LEAD Apple to know that, just because some geek engineer CAN do something doesn't mean it SHOULD be done. SERIOUSLY SAD!

Best music app for the non-techie! PLEASE FIX THIS APP!

Since the last upgrade it crashes immediately!I absolutely love this app. The cross fader and best of all the ALX technology blows the competition away. Would like an option for a brighter background for the daylight!
