SC will not take 18-bit wavs.
i have a program that will let you convert any sound file to any sound file (almost), 8, 16, or 18 bit and you can choose the hertz..
ill see if i can change it to 16 bit.
ADDITION:
Urmom, its a direct link to the wav. right click and click 'save link target as'
noob.
(jk

)
ADDITION:
Ok, got it. I saved it as the same everything, i just changed the bit to 16.
i didnt want to make the hertz any higher, as im not sure if you online and i dont want to wait and ask you..
ADDITION:
Actually, i wont do it.. its gone from a 508 kb file to a 3 meg file.
ugh.
