after trying out (so) many equalizers.. apk's, this is the very best one of them all absolutely, the sound quality is superb and its much better than an "SP mod mcu", the sound note is incredibly audible and everything is on his right place, you hear every little detail of the song note coming from your car speakers, really amazing.. according to my hearing, it was an enjoyed ride listening to Jackie Brown (movie songs) 110th streets, Barry (Black) White, Tony Brixton, L. Richie and so on.. I didn't like the vaper4android much so I didn't "installed" it second time, instead of it, I used another equalizer, but this new one is oh man oh what an incredible sound quality this combination of headunit-car-speakers you gonna get from this: Eqfy Equalizer v1.1.3 build 24.apk mate.
Settings of the car headunit:
Pop & loud + reduces the boss (tastes is different indeed) gain a bit.
Settings of the Eqfy (click on 3 ... dut) equalizer:
Pop + increases the gain up to +10 or +12, (tastes is different!)
gain boost is checked/ticked,
enhanced bass is checked/ticked,
bands overlap is checked/ticked,
you do not need any custom (sp) mcu etc after you (using) listen to this new one mate.. the heard sound music sounds like a expensive hi-fi installation (like the Yamaha dsp1 which I had in the long past) and it is even much better.
I wanted to share my experiences with you guys so that you gonna enjoying listening to your lovely (old) songs on the highway.
Oh, before I forget.. google is my dear friend.. you understand me.. right?.. you're welcome mate.
