So I saw some dude on YouTube named Dale doing some pretty cool video reviews. I think he might be on Headfi, but I'm not sure. Anyway, he had this really cool EQ program that he used to "correct" the EQ on his headphones to compensate for weird peaks and valleys in the FR. This program was way more sophisticated than the EQ apps we see on the Google Play Store. Does such an pseudo-professiin app exist for Android? This would definitely be the kind of thing I'd be willing to pay for. Thanks!
