A command-line tool for generating audible noise.
Listening to white noise can help me sleep, especially when there's a more annoying type of noise that needs to be drowned out. There are 10+ hour-long YouTube videos for this, but it's a bit overkill to use a video streaming site for something as simple as white noise.
wn is a command-line tool that lets you generate your own white, (or brown, or pink, or ...) noise.
