Needs Export for Equalizer

As an audio engineer, this app really does get the job done when it comes to increasing volume and enhancing music however, there is currently no option to export the music with the equalizer settings applied. So, only option in left with is to screen-record but, that introduces compression to the drums in my mix which is no-good.

TLDR: I would appreciate it if you guys could add the option to export with EQ Settings, it’s the only reason I didn’t give 5 Stars.

Enhancing the audio quality and very effective performance

When I first downloaded the free app and heard what it could do, only quality of sound but also it's potential I more or less straight away paid for the full version which can I say gave the same performance. I have rated it 5 but I have a problem which will have most folks smirking in their coffee mugs because no matter how much I keep trying, looking, studying and researching can I bollocks find how to bring up settings so I can access the Equalizer. Please can someone just tell me . Many thanks

Its really working unlike the other

great app but . when you get down to it, there should be no need for this app because you should put vol limits on our phones in first place !!! this app unlocks phone vol and sounds great ! is this as loud as phone can go ? who knows but its way better the default vol of this phone !!! im going to go try it on my kenwood system with some 10 inch piles ,it should 10 times better with this app ! thank you very much to who ever made this app!
