[Openal] Re:Exploding Filters

[Daniel PEACOCK]

Hi,

I think there were only minor changes in the efx.h file (some corrections
of default, min, and max values).

There must be some difference(s) between EFXFilter and your application ...
perhaps some changes in the project settings, maybe the choice of runtime
libraries ?  If it is possible can you modify the EFXFilter application to
duplicate the settings you are using to see if that shows the problem as
well ?   What compiler and version number are you using ?

Hi again,

The EfxFilter test app seems to work ok and I can definately hear the
filters working on it. I think I'm using the typedefs from the efx
header...heres the code where I use alProcAddress:

alIsFilter = (LPALISFILTER)alGetProcAddress("alIsFilter");

I use the same method for all the other efx functions too which seem to be
working ok.

I've updated my x-fi driver to the latest version just to be sure too but
alas no joy.

I forgot to say but I think I have had the filters working in the past
when I first integrated the efx extention...could I have somehow bodged
the update to the new version of the 1.1 sdk? There didnt look like there
were any major differences in efx.h that were to do with filters. I've
gone through the headers and libraries and made sure they're all up to
date and that I've got the new version installed.

Whatever's causing it isn't affecting alEffectf either and I can happily
set parameters with that.

Cheers

Col
