NAME
       abx - audio ABX testing software

SYNOPSIS
       abx [OPTIONS...] <SAMPLE-A> <SAMPLE-B>

DESCRIPTION
       abx is a program for performing software-based audio ABX testing on
       GNU/Linux systems. ABX test (Wikipedia, Hydrogenaudio) is a statistical
       test for assessing whether you are able to tell for audible differences
       between two samples. For example, one sample can be a compressed audio
       file such as OGG Vorbis file and another one its uncompressed variant
       (WAV, AU, ...). You can then use abx to infer whether you are able to
       separate the two samples due to compression artifacts.
