Adjustable audio peak hold time

[frspp]

Hey,

I think it would be useful to be able to adjust audio meter's peak hold time. For example if you're shooting yourself with integrated microphone and cannot see the screen while testing the mic volume, with ~15 second peak hold one would have enought time to go to see the meters from  the screen. Maybe it could have few options like 0.1, 1, 2, 5, 10, 15, 30 seconds (or fully adjustable)? I would quess this quite easily to do, but am I wrong?
