Description:

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.
- Check if your answers are correct.
- If you could answer correctly for X1 through X5, you can proudly declare that you can distinguish the difference coming from the different compression ratios. Congratulations!

Features
- You can pick test samples A and B from your music files.
- You can play test samples A, B and X during your test.
- You can answer whether played X is A or B.
- You can try five times in one test.
- You can get the percentage of successful trials.

Future Plans
- Enable users to change the number of samples to try.
- Enable users to save the test results.

System Requirements
- Mac OS X 10.6 or later

Please add auto-gain - Does exactly what I was looking for. I wish it had an auto-gain though, or "soundcheck" so that both files would be equally leveled.

Review by Doug Young

Nice and easy to use - Nice little app, and the price is right. I wish it allowed more than 5 trials for more accuracy, and I'd feel a lot more confident if it didn't report the results as "persent" (mispelled!).

Good, but want more file support. - I was looking for an ABX tester for mac, and this is the only i found that will work, but I would love support for 24 bit flac, etc.

Review by rakingleaves

Great little app - I'm surprised no one has reviewed this yet. This app works exactly as advertised and is very useful if you're not sure what bitrate to use for ripping music. The UI is a bit rough around the edges, but it was easy enough to figure out how to use. Very glad to have found this.
