Digital dynamics and volume level ????

If a digital signal is typically on or off, how does it interpret volume levels and dynamics ? I can understand how an analogue signal varies in level and intensity but am lost trying to contemplate what happens with digital. What brought this up is the fact that i just picked up a CD that is quite dynamic and recorded very well ( Blue Man Group: Audio ). It consists of almost all home-made PVC tubing based instruments, most of them being percussion oriented. I bought this after seeing their "show" ( long running "stage art" here in Chicago ) as i really dug the music. Volume levels were pretty loud, actually shaking the floor and our seets at 100 foot distance on some "drum" whacks. The CD volume level is pretty even except for one cut, which is much lower than the rest. On first listening, i almost thought that my girlfriend had snuck up and turned the volume down or that something happened to my system. If digital is either off or on, how does it interpret the various levels ? Anybody have an explanation that we can understand ? Sean |
