4. TECHNICAL BACKGROUND

4.1 What are audio dynamics?

A remarkable feature of the human ear is that it can detect the widest range of amplitude changes—from the slightest whisper to the deafening roar of a jet-plane. If one tried to record or reproduce this wide sound spectrum with the help of amplifiers, cassette recorders, records or even digital recorders (CD, DAT, etc.), one would immediately be restricted by the physical limitations of electronic and acoustic sound reproduction technology.
