I find it bit too loud for my taste, willing to replace it with the shutter sound from a Leica M8. AFAIK the default screen capture action (triggered with the cmd-shift-3 or cmd-shift-4 keyboard shortcuts) sound isn't something you can change with apps like Onyx or MainMenu -the ones I have tried so far-. So, does anybody know where such wild thing is hiding?, I have found the files for the Grab.app but that's not what I am looking for.
Thanks.
