An ABX test, often used in audio testing and research, is a method for comparing two stimuli (typically audio samples) to determine if a listener can distinguish between them. In an ABX test, participants are presented with two different audio samples, labeled "A" and "B." They then hear a third sample, labeled "X," which is either identical to sample A or sample B. Participants must identify whether sample X is A or B.
