Adding dither is mixing the audio with some random noise. It has two effects: The sound of jitterCsaba Horváth published a test with dither from bit 12 to 16. Gives you a taste of how it sounds and the magnitude. As the file contains no audio, it gives you also a taste of the contribution of these lower bits. Indeed you have to crank up the volume substantial to make them audible.
