Thank you john33!

Why data format changed from SHORT to FLOAT?
May be vbDecRead changed to FLOAT output too?
I have only 16-bit samples and now must convert it to 32-bit float format, but standard Vorbis SDK work with SHORT samples!
Can you send me vorbis.dll sources or header?

I am guessing that the only reason it was changed to float was because DarkAvenger wanted to pass float values to it from within HeadAC3he.

You can d/l the source for the dll from: http://homepage.ntlworld.com/jfe1205/vorbisdllsrc.zip
