Leveling Axe-Fx II Presets Using Pink Noise and Loudness Meter

Nothing can truly replace leveling presets live, with the band, using your ears. But if you need to get things close, and you can't open it up to full volume to test levels using a Db meter, this approach works pretty well.

Software Required

You'll need a pink noise generator and a loudness meter application. I'm on OS X and I use Noisy for pink noise generation and Orban Loudness Meter for measuring. Both will work using the Axe-Fx II's USB in and out on OS X 10.9.x. They also both happen to be free which is nice.

A quick script that fetches desktop images from the http://simpledesktops.com/ site.
 
It will start at the most current list of images and keep moving backwards, downloading
desktop images in to a directory on your local machine, until it finds an image that
already exists on disk. At that point it will stop.
Something went wrong with that request. Please try again.
