[FFmpeg-user] silencedetect floor

[Josh McNeill]

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.
