Great EQ/Mastering – Equalizer Review
I use this to master my garage band songs on my iPhone. This app isn't intended to be a "mastering" tool but gives me more control than other "big name " pricy apps like "mastering by Howie Weinberg" (what a sorry excuse for a mastering tool). I tried several others, this was the best for cleaning up the 20-60hz range and leaving a solid punch by a mile. I highly recommend this app.
