I know this question should belong to a general replaygain thread. I just want to piggyback on my recent discussion for a quick answer on this:

I have few audio test files with samples like "silence" or "pink noise". These samples happen to bear a trackgain value of let's say 922... billion dB (seriously, an endless string, very large positive number). What would happen (to my system) if I ever played one of those files with trackgain enabled?

The number is + and the string convOut=-af volume=replaygain=track implies to me that the 922 billion would become subtracted but I am not sure...
