+abx is a program for performing software-based audio ABX testing. ABX test is a
+statistical method for assessing whether you are able to tell for audible
+differences between two samples. For example, one sample could be compressed
+audio, such as Ogg Vorbis, and another one its uncompressed variant. You could
+then use abx to infer whether you are able to separate the two samples due to
+compression artifacts.
