DESCRIPTION:
K-System K-20 Pink Noise Calibration Tones
Use this to calibrate the YouTube volume

I use this to compare volumes from my browser/Youtube to whats in my studio, sometimes levels don't match up, so this is a way to calibrate it........Not sure how to setup or what this is.... Google Bob Katz, K-System Calibration

//Note make sure you have Youtube playback volume turned up
//Also make sure you have any sound enhancement features
//turned off
//And make sure your playback quality is HD1080p
