Looking for a frequency-domain sound library

Is there any such thing out there? It seems that all the sound libraries (including FMOD) are mixing sound in the temporal domain.
This doesn't allow sound effects to be easily implemented / mixed.

which effects do you have in mind that can be easier done in frequency domain?
i think that FMOD is quite close to perfect. so i'd be interested in what you are missing...

Did some research and it all make sense now: it is much faster to calculate convolution in the frequency domain (hell, I am not sure it can be done otherwise).
Game Programming Gems II mention that it is faster to convert your signals to the frequence domain and use the FFT.
For those who don't know, convolution is a mathematical operation. In the case of sound mixing, the convolution is used to fake 3D audio positioning and modify the "ambiance". Think playing your sound in a cathedral or a stadium and having the mixer figure it all out.
So yeah, I am still looking for such a sound engine. Anything?
