ED; supplied proper link...
Yeah, I think what synchromesh is saying is that this could be handled
(though with a huge amount of uphill trodding) by opening the
soundbite in something like https://www.audacityteam.org/ and editing
the volume to the desired amount.
True-- an enormous roundabout far out of the way, and off schedule,
(may require testing and retesting), but it should certainly work.
You may want to put your ambient sounds next to the footfall sounds
in two audacity editors to compare before going back and forth between
GG testing. Sorry for that.
// Q: Does every internal sound volume setting become global to effect
all other sounds? Now that I think of it, this could be the issue that
I have noticed-- just didn't know what was happening? //
