Absolutely Fantastic!

I setup a friends stereo in his garage with this app. I got him to purchase it aswell once I showed him the RTA and DB Meter (he loved the app too since he is a professional musician and this app can help when he sets up for his gigs). But in his garage, the surfaces of everything was so hard that the sound was irritating! So we dialed in each frequency of the EQ (little 7 band). He hooked up his iPhone through the stereo and using the Signal Generator he set each frequency to the band of the EQ (the EQ was set completely flat for the baseline test). I went to the middle of the garage and measured the SPL with my iPhone. Once we knew the base SPL of each band of the eq, then he again applied the frequencys throught the stereo and we adjusted each band (one at a time) until the SPL was the same on each band. Now you can stand anywhere in the garage and it sounds fantastic. We adjusted the response of the system in the room and now is completely balanced and the clearity is unreal! There are no harsh tones and has fantastic stereo seperation. It worked so well there is only about .5dB loss from one end of the garage to the other. Im currently looking for dual mono 30 band EQs for myself just so I can fine tune my home audio system with this app. I have also used it to tune my bass guitar (adjusting the pickups) so the volume of each note is within about .5dB of each other. I have tuned car stereos, setup for friends gigs, etc. If youre an audio nut, you will love this app! Keep up the great work guys!
