Boodler is the name of a free, open-source application written by Andrew Plotkin to create soundscape simulations. We’ve all heard CDs of thunderstorms or seen clock-radios that have built-in sound effects to let you go to sleep to the sound of crashing waves or birdsong; this is like those, only:

* You run the software on your computer—Linux, Mac and Windows are all supported
* You don’t pay anything for the software, or get to download for free but are then nagged/guilted/limited into paying for it
* The software also comes with bundled soundscapes which are free for you to use
* Unlike CDs or even radios and other software audio generators, Boodler’s soundscapes can contain a level of complexity as deep as you can imagine with sound quality as good as high as your hardware can support. This means you can design soundscapes to never play the same thing twice, for example—a common problem to those who would use such tools as sleep or meditation aides, for example.
