fader n.

early 14c., "lose brightness, grow pale," from Old French fader "become weak, wilt, wither," from fade (adj.) "pale, weak; insipid, tasteless" (12c.), probably from Vulgar Latin *fatidus, which is said to be a blending of Latin fatuus "silly, tasteless" and vapidus "flat, flavorless." Related: Faded; fading. Of sounds, by 1819. Transitive sense from 1590s; in cinematography from 1918.

Adieu! adieu! thy plaintive anthem fades

  Past the near meadows, over the still stream,

    Up the hill-side; and now 'tis buried deep

      In the next valley-glades:

Was it a vision, or a waking dream?

  Fled is that music:" Do I wake or sleep?

[Keats, from "Ode to a Nightingale"]
