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.
