ultra low latency AD interface for visualization purposes

Hi,

I am currently doing research in the field of realtime audio feature extraction for visualization purposes. Basically I am building an AudioGraph and using AudioUnits to analyze the stream and feed a graphics layer (similar to the SonogramDemo). Of course you would want the lowest latency possible during the whole process.

Now, to test my results in a real-world scenario, I'd need a reliable multi-channel audio interface that offers stable core audio drivers and very low latency AD-conversion (preferably with pre-amps). I am neither asking for a buyer's guide, nor I want to start a discussion on anybody's favourite interface, but I would appreciate any recommendations for this kind of use case.

So I  guess it boils down to these two questions:

Which interfaces are known for a very low latency for Analog -> Digital -> AudioUnit Host flow?

Will a firewire interface be fast enough to convert 8 simultaneous input streams and feed the AudioUnits in realtime or would you rather recommend a PCI-solution like Apogee's Symphony?

thanks, and my apologies if this is off-topic on this list.

Heinrich Fink
