There is a command-line program called VU at:


It is character based, but you can adjust the
resolution up to sample level if you want.  I
used it once in a class where we were supposed
to analyze the level of a piece of music over
time by watching the VU meter on the tape recorder
and trying to match it up to a graph with a 
stop watch.  This was in like 1990.  I wowed
the class by showing up with a huge dot matrix
greenbar graph of the piece.
