abx

Simple ABX tester to compare audio files with GUI

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.
