This document addresses how to create audio noise & tone files using Adobe Audition.
Audition Overview
Generating Noise
A note about Adobe Audition's noise. It's close but it's not scientifically close. Don't use it for measuring acoustical spaces. Here is a professional real-time-spectrum analyzer (SMAART software) screen grab of the difference between measurement pink noise and Audition's pink noise. The measurement pink noise is not perfect either, but it is much closer, with its delta being .2dB. Whereas, Auditions pink noise delta is 1.07dB...or 5 times greater than measurement pink.
