ABXTester
ABXTester is an Mac application to conduct ABX tests for you.
An ABX test is a method to examine if you can distinguish two sound samples A and B. In an ABX test session, a sound sample X, which is randomly picked from A and B, is played, and you have to answer if the sample is either A or B. You repeat this trial multiple times and then get assessed if you can really distinguish A and B.
