The term dynamic range has a precise mathematical definition that relates back to
quantization error. In the context of music, we encountered dynamic range as the difference
between the loudest and quietist musical passages of a song or performance. Digitally, the
loudest potential passage of the music (or other audio signal) that could be represented would
