Moreover, most applications are actually usable with no sound, which is why audio can easily be purposefully neglected or just overlooked during development.

Fortunately, there are tools that facilitate producing okay-quality sound effects while possessing zero domain-specific knowledge. A perfect example is Bfxr, a synthesizer specifically aimed at sporadic game development. It is available for free at www.bfxr.net.

The usage of Bfxr family of tools boils down to clicking preset buttons until it generates a nice sound, and then hitting Save to Disk to store the result as a .wav (uncompressed sound...
