Simple ABX Tester

Simple ABX Tester is a simple and intuitive audio abx application that enables you to perform double blind listening tests on your Android device.

Automated mp3 test preparation
- select a lossless file and the desired compression setting: app does the rest for you.
- after the required files are encoded, decoded and synchronized, an intuitive testing interface enables randomized, blind and tell-free abx testing.

Self-prepared mode:
- for testing other encoders/decoders
- requires you to provide the required source & externally encoded/decoded files yourself, using WAV format
- automatic synchronization

Intuitive interfaces:
1) ABXY - match tracks that sound the same using drag and drop; inspired by Foobar's ABX plugin
2) ABX - select one of two tracks that matches the reference track

Automatic track synchronization: no audible tells when switching between tracks, no silences, no popping noises.

Simple statistic that tells you the likelihood of achieving the same result by random guessing.

Test access to protected storage
Modify or delete the contents of your USB storage
- raw audio takes a lot of space, so this enables you to choose the directory where the app generated files are saved (for example to an sd-card or a USB drive)
- enables the sceptics to test for the correctness of generated files, as it exposes the generated files to user accessible space

Prevent phone from sleeping
- encoding can take a few minutes on weaker devices; this enables you to turn off the screen (thereby saving battery) while the encoding takes place uninterrupted in the background
