I think Altiverb can already emulate EQ's..I'm not sure about compressors but I assume it would be able to. As far as I'm aware, the process of capturing an acoustic space is similar to capturing eq; throwing a testsweep through a space or device, sampling the result and processing it to fingerprint what happens to the testsweep. Mics, EQ's, spaces and possibly even compressors can be emulated like this with great detail and accuracy. Unfortunately the interface of Altiverb is geared towards reverb at the moment; if you'd want to capture a Pultec for instance, you'd have to sample each combination of all the knob settings! I presume the Sintefex's interface has been designed towards eq, and it probably does some nifty crossfading of convolution impulses to allow all the different variants/knob positions of the original (sampled) unit. Convolution has a wide area of application; I think the same technique is used in Antares Mic modeller for instance. Anyway, I suppose somebody with Altiverb, a Pultec and a lot of time on their hands could probably make some good sounding presets, but from an interface standpoint it would be pretty unuseable right now.
