MEX files for 32-bit MATLAB on 64-bit windows

It appears that 32-bit MATLAB on 64-bit Windows is an offically supported configuration.

What type of mex files (32/64 bit) do you use in this configuration? I found some comments on CSSM that suggest 32-bit MEX files, but I cannot find anything offical from TMW.

You use .mex32 on such a configuration. It is just running the 32 bit application under Windows-level emulation, and that emulation is going to expect the whole thing to be 32 bit.

That makes sense. I was thinking about this in regards to portaudio where pawavplay and playrec only work with 32-bit MATLAB (I think). I wonder if the Windows emulation will get in the way of portaudio.

In theory it shouldn't, but I'm not certain it is possible to understand MS Windows architecture without certain mushroom extracts (and I'm allergic to mushrooms.)
