on that page the creator says you can get the paid version for free from his website. I went there n got it. about to test it out now.
edit: after getting annoyed trying to compare by ear by going back n forth cutting it on or off, I wanted to make sure it wasn't a placebo effect. well decided to get free decibel meter from marketplace and put it on my Atrix to get some real readings to see if this really works. its official, it does work..lol. it showed consistent higher decibel readings with speaker mod cut on. I have my settings at good quality. volume +5 and bass +2. it sounds great. I thought it sounded loud before but with this its super loud n clear also. with bass increased +2 I can hear n kinda feel(in my hand..lol) it more. don't forget you can just go to the guys website n download the app paid version for free. thanks for the tip. afraid to mess with settings anymore as i don't wanna blow the speaker..lmao. still a test in progress though. if I hearanything funny, I will immediately shut it off..lol
