[Openal] Any floating point extensions?

[E. Wing]

Are there any extensions (particularly on Windows) for floating point
samples? I am throwing my captured samples at FFTs, but the libraries
I use require floating point and I know int to float conversions are
not necessarily cheap. I know the Apple implementation used to support
floating point, but the constant has been removed from the headers
(but it actually still seems to work if I redefine it). I would like
to know if I can get it on Windows too (and if its being considered
for future revisions of OpenAL).



Thanks,
Eric
