Dear @bsmg: """ ears are analog. " Whom told you that. Things are that we all have in our brain/ears an ADC. In reality our ears are digital:
""" The Inner ear:
By now, the audio signal has reached the inner ear, and that means the cochlea. This snail‑shaped organ is filled with liquid. Logically enough, it must be waterproof, in order to prevent any fluid leaking. This explains the purpose of the round window, a small, elastic membrane on the surface of the cochlea. Its purpose is to allow movement of the fluid inside the cochlea. Liquids are incompressible, and without this membrane, the fluid enclosed inside the cochlea would completely block the ossicle movements. Indeed, stiffening of the oval window can lead to hearing losses of about 60dB.
Inside the cochlean we find the tectorial membrane, which moves along with the pressure variations of the cochlear fluid. As shown in Figure 3, above, this membrane is in contact with the cilia on the top of the hair cells. There are two kinds of hair cells. The outer hair cells are the actual receptors. When the tectorial membrane moves, so does the hair on the the outer cells. This movement is then encoded into electrical digital signals and goes to the brain through the cochlear nerve. The inner cells have a different role: when the audio signal gets louder, they stick themselves to the tectorial membrane in order to limit its movements, playing the role of another dynamic compressor.Figure 3: Inside the cochlea.

This is not about analog vs digital but about each one knowledge levels.
