Hi renato,

only saw the question now, so sorry for the late reply.
The input voltage of soundcards depends on the headroom of the AD of your soundcard. (e.g. Dynamic Range).
Pro and semi-pro cards often have a line level of +4dBu (1.227V RMS, 3.472V Peak) plus a bit headroom.
Hope this helps.

Hey,
this has been so fun for me I figured it could be for some of you
also... Today in 2-3 hours I've built a 2 string fretless bass following
more or less this instructable:

short demo (sorry for unfriendly site... don't know where else to put
it):

It's incredible the sound it has considering it's a piezo stuck between
some scrap wood and weed-eater strings

The piezo is putten directly into the soundcard and it clips... I should
parallel it with a zener diode... BTW what is the max voltage before
clipping on soundcards? is it soundcard-dependant?

No offense to real basses meant... of course it's only a game... but I
suggest trying it!

cheers
renato
