Oh, that wasn't the issue. I want it to detect silence below, for
example, 0.01 for the amplitude ratio, but I want it to not detect
absolute silence, i.e. where the amplitude ratio is simply 0, so I
wanted to set n= to a range, like 0.001 to 0.01, so that it will ignore
absolute silence but still tell me where the non-absolute silence is.

I'm glad to know it's possible. Unfortunately, the documentation doesn't
give me any clues that have been helpful. I've looked through the
documentation for silencedetect, silenceremove, noise, and filtergraph
syntax. I've even tried just searching through all the documentation for
"amplitude" and "noise" and "silence" and have yet to find anything that
tells me how to accomplish this. The only thing I've found that says
anything about specifying a parameter value as a range is under 38.145
readeia608, which suggests using [value - value], which naturally
doesn't work for silencedetect's noise parameter. I've also asked this
same question on the Super User Stack Exchange and did not receive a
single response. I've exhausted all my options, including looking at
documentation.
Just set it to some number, like "-40dB" or 0.05.

I'm trying to figure out a way to detect silence with FFmpeg but not
absolute/digital silence. Is it possible to set a floor somehow with
silencedetect so that I'm detecting sound above absolute silence but
below some threshold?
Yes, it is n/noise parameter, read available documentation.
