I would like to reiterate the suggestion I made to welly in the thread with samples... bottoming out sounds should be removed from the samples if possible, especially on clicky switch types. The sound of bottoming out on a cherry brown is going to be more or less the same as the sound of bottoming out on a Logitech rubber dome. This current method with bottoming out sounds is not at all helpful for delineating switch sound, since the sound of a rubber dome, linear, or tactile non-clicky switch bottoming out will be darn near the same on every board and is really more a difference in recording setup and clip quality. If you need to hear the sound of one of these boards bottoming out, just hammer on any key of any keyboard that DOESN'T click, and you'll pretty much have it.
Sorry, I don't mean to be a killjoy, but this idea has never made sense to me the way it's being implemented.
Also, if you bottom out as hard as many of these recordings, you'll have to jack up your volume to hear the sound of someone else bottoming out over your own bottoming out.
Audible feedback is a nice feature to keyboards, but many of the ones used here, and many of the most popular on this site, DO NOT have any audible feedback inherent in the switch design. The only sound is the keycap clacking down against the switch housing when reaching the end of travel. These designs are just as worthy as clicky switches without a doubt, but don't make much sense for a "sound test" application.
Oh well, I hope I didn't hurt any feelings...
