Here's another simple test to hear what different types of dither and noise-shaping sound like on music:

Play any music or sound source from within the DAW utilizing a digital master fader at the final output, but with the fader PRE-dither/noise shaping. The dither/noise shaping plug-in or device MUST be post-master fader for this test to work. Pull the digital fader down to the point where the audio is just barely audible. Compensate with the analog monitor levels so you can clearly hear the music. BE VERY CAREFUL! With dither OFF, play the audio and adjust the digital master fader to the point where the audio chatters and sputters. You are now hearing the effect of Least Significant Bit chatter at the DAC. Now engage various types of dither or noise shaping and listen to what happens to the audio. Even with the application of the simplest dither you'll notice the chatter goes away. You'll easily hear which dither is most effective and least obtrusive with this test. Try different bit depths; i.e.: 16 or 24. BE SURE TO RESET THE MONITOR LEVELS BEFORE PULLING THE MASTER FADER BACK UP WHEN FINISHED!

After listening this way for a bit (pun intended) you'll clearly hear dither or noise shaping right through the music at normal listening levels.
