audio ABX testing software
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.
