PLATE 1871 — SYNTHETIC AUDIO DESCRIPTION

This is generated sound, not a recording of the studio, the Operator, or the
November room. It carries no clue that is absent from this description.

00:00–00:08  A low steady tone enters under a narrow band of noise.
00:08–00:11  The tone rises and almost resolves into a stable interval.
00:11–00:14  The expected stopping point passes. The noise begins to widen.
00:14–00:40  The tone remains, but the field around it grows broader and less
             legible until it resembles weather more than a mistake.

The Operator would have stopped at eleven seconds. The loop continued to forty.
