Noize
Your Personal Ambience Sound Mixer
Free | Website | Web Version
Noize is a small app that lives in your menubar and plays a variety of sounds to help you relax, concentrate or simply drown annoying background noises around you. It offers 15 different sounds and allows you to mix and match them as you wish with 6 volume levels for each one.
I honestly don't have a lot of free time lately so I'm just going to be posting individual apps that I enjoy and use frequently (starting with less popular ones), since that takes a lot less time than preparing an entire list of related apps. I'm not abandoning the idea and I think it's useful to have them but it might take a while.
