Customer Reviews

This became my go to music app within 24 hrs of installing

Fantastic options I’ve never seen on any other iPhone or iPad Music playing app before.

It recognizes Replay Gain
It resamples your music to 32 bit
It shows you how many MBps second are being played, How long with source sample rate and format
It allows for automatic gain control
Also gives you a preamp
And gives you what I consider to be the best array of equalizers I’ve ever seen

You can get a classic 10 band equalizer or 30 band parametric equalizer and everything in between

It will play your Podcasts and let you adjust the sonics of voices

I don’t remember honestly if I paid a little more I think I did because I was so rocked by what they give you for free

Simply put I am taking time to write this review because the app is f’ing awesome.


Destroys I Tunes Player

So recently ive been searching through audio equalizer apps for ios This is the best i could find so far though not a ten band equalizer. Just a music player with tons of great features like pitch control Surround and an amplifier On top of the 30 band parametric equalizer . Highly recommend. Except it may be too much for an ipad sometimes cause it lags whenever i play a new track the first time around

Wow! Awesome Music Player

While the interface may not be the most intuitive, this is truly is an amazing app. I stumbled across this from a review on in-ear-monitors. This player rocks! Can't recommend this enough, if you have some patience this is a great addition to your app library to enjoy your music at a different level!
