Hi.
I'm learning an ace production but it makes a little bit of noise.
Is that ok for the spectators, will they say anything?
I thought that maybe it's taking the magical value a little bit away...

Why don't you perform it and find out?

You've got two options as I see it. Keep practicing until you can do it noise free, or take your chances performing it now. It's possible they won't notice. If the sound is very faint you can cover it just by talking while you're doing the move, that way they'll be watching and listening to you instead of the cards. Still, I reccommend the first option. I can't count the times I've worked on a noisy sleight that I thought I would never be able to do quietly, but it always came with time, and it was always worth the time spent.
