Adventure Kid Wave Forms are a collection of sampled one cycle waveforms for use in synthesizers or similar sound generators.

A technical reason is that 440Hz (or its multiples) plays nice(st) with common recording frequencies such as 22.05kHz, 44.1kHz, 48kHz, 96kHz, etc. Taking 44.1kHz for example, if you divide 44100 samples per second by 100 cycles per second, you get a clean 441. Meaning that if you would concatenate 100 single-cycle waveforms you would end up with a perfect 441Hz pitch, which is only an 1Hz error (barely audible if put side-by-side). Being able to work in integers like that is extremely beneficial for "lighter" variants of DSP algorithms (such as resampling algorithms) - it may help reduce aliasing as well as manual sample editing or synthesis (one of the reasons why the AKWF single cycle collection were originally created at a multiple of 100 samples as well).
