Unless it has changed under 10.8 (I haven't checked, but doubt it), you only have a few basic vector ops in the kernel version.

You have to build the FFT in your kext yourself from source.

Having done this recently, I may be able to help if you want to contact me directly off-list.

Cheers

Hi.

I'm currently working on a Audio USB Driver. I would like to add some effect on audio buffer, so I need to use complex algorithm such as FFT.

So I would to know if i can use the Accelerate framework in kernel mode?

Thanks for your answers.
