Buckle emulates the sound of an old IBM Model-M space saver bucklespring keyboard while typing within an X session.

It runs as a background process and plays back the sound of each key pressed and released on the keyboard, just as if using an IBM Model-M. The sound of each key has carefully been sampled, and is played back while simulating the proper distance and direction for a realistic 3D sound palette of pure nostalgic bliss.
