StultitiaSimplex - A simple "Soundboard"

Current Version 1.3.1



StultitiaSimplex is a simple, platform-independent "soundboard" application.
With StultitiaSimplex you have the silly audio clips of your choice easily at hand whenever you need them.
A record dialog for recording audio clips is included.

Supported Operating Systems

Currently, Linux and Windows are supported.
A special version adapted for Maemo 5 (Frematle) is available as well.
See also Software Requirements.


Q: What should I use StultitiaSimplex for?

A: Well, I assume that you do not use StultitiaSimplex for serious work or quoting the general theory of relativity.
Instead, the typical use of StultitiaSimplex is rather to have silly audio clips quickly at hand to make fun or to annoy your colleagues.

Q: Why did you choose the name "StultitiaSimplex"?

A: As the intended application field of StultitiaSimplex is rather silly (see above) the name should give that intention away.
Further, another goal was that StultitiaSimplex is as simple to use as possible and features a user interface that is stripped down to the absolutely necessary.
Hence, the name "StultitiaSimplex" is the combination of the two Latin words "Stultitia", meaning something like "silly", "foolish", or "stupid" and "Simplex" which means "simple".

Q: Why did you choose "?!" as your icon?

A: Hopefully, the reactions of your audience will be like "wtf?!" or "lol?!".
To express this intention "?!" had been chosen as icon.
