fileABX is a freeware Windows command-line utility that allows to
perform wav file-based ABX tests. Summarizing, it generates
ABX-randomized copies of the wav source files specified, and the
listener has to identify them just by listening.

It can be useful for performing long-term ABX tests, and also for
using your favourite audio equipment and player, whether software or
hardware (wav files can be burned to CD), to perfom an ABX test.
