- Yes, you add white noise (hiss) at a level equivalent to the amplitude of
- the least significant bit in the 16-bit word. This is at -96 dB, completely
- inaudible under most music.

- This is far below the level of hiss from analog magnetic tape - thus the
- claim of "absence of hiss". It isn't absolutely absent, but it's at a
- far lower level.
