This software consists of XMMS plugin and stdin/stdout plugin. It was written for realtime remastering of sound from mp3 files. You will need a reasonably good stereo and a good ear to notice quality improvement, otherwise this is not for you. This plugin tries to patch mp3 format flaws, not a poor audio hardware! Yes, you should be able to hear well enough (sorry) - for some of my friends plugin is a cool thing, while the others does not hear nothing but echo and stereo expander (well, you will hear every effect if you set it to the maximum, but it will not sound nice).
