Got Accudio today. I have owned equ and equalizer since they came out. Equalizer was always my faveorite.
Accudio blows them both out of water. Its a really incredible app. Aside from the fact that it is designed exctremely well, and never crashes, its ability to bring headphones to true neutral is ASTOUNDING.
i am a bit of a neutrality nut, and have spent months/years chasing neutrality on whatever headphonnes i've owned. I have had my westone es-5 customs dialed into pretty darn close to neutral for a long time but always though it could probably be done better by someone who really knew what they were doing or had good equipment... well actually i thought it may never be done because who the heck has the ability to do this except a very select few, and especially on customs!?!?!??! Wel i have to say they NAILED IT! its actually similar to my eq curve (pats self on back ) but i am not ashamed to say this app has one upped me and my es-5's have never sounded better.
there's so much more.. the ui is very intiuitive, they support flac, and ogg, their parametric eq is THE BEST!, the eq settings within the headphone you select as yours works very well, and auto regulates the gain so you never distort.
I could go on and on. THIS IS THE BEST EQ APP EVER - BUY IT!!! especially if your headphones are on their list. if they can do for yours what they did for my es-5's and you have an open mind to what true neutral is supposed to sound like you will NOT be dissapointed.
