2. Open an Audacity project and create a new track. The track header should indicate a 44,100 Hz sample rate. If it is different, change it by clicking the “...” drop-down menu in the track header (shortcut shift-M) and setting the Rate to 44,100 Hz.
Go the Generate menu and select Noise -> White, at a moderate amplitude (around .5) and for a duration of 15 seconds.
Create a new track with the same settings and generate pink noise.
Create a third track and generate Brownian noise (also called Brown noise or red noise).
Audition the tracks. Solo each track in turn to compare them. Describe and contrast the three sounds, using any descriptive language (whether technical or metaphorical) you like.
