Two notes Torpedo

[12afael]

I'm interested in build myself something similar to the impulse based cab simulator of Two notes.
there are some real time impulse loader for linux like Jconvolver it work on linux but I would like to implement it on something like a raspberry pi.
The two notes producs have a latency of 1.9 to 4.8 msec and it is reasonable to think that they are using a solution with an operating system because they have to comunicate with a computer and they handle files.

I wonder if someone know what kind of processor are they using on their products.
