Junk, skip this one and save your money.

Prior to this complete overhaul it was one of the best sound tools available in the App Store and the only one I would recommend. Performance Audio, if you value these reviews and correct pore design and implementation by restoring the previous version with only the optimizations to support the latest hardware I will change my review back to 5 Stars, until then Im restoring the previous version from my backup and if anyone is reading this prior upgrading DONT WASTE YOUR TIME!
