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.
ABX test and ABXTester are useful when you need to asses objectively if you can distinguish the difference in sound quality between two sound samples originated from same single sound source but with different compression ratios.
Usage
- Prepare two sound samples A and B with two different compression ratios from single sound source, or music.
- Launch ABXTester.
- Select the sound samples A and B.
- ABXTester prepares five sound samples X1 through X5, each of which is randomly picked from A and B. For each sample, listen carefully and answer whether the sample is either A or B.
