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.
