* This image was found on Page 77 in a documented called "The Typophone: A Talking Typewriter", Proefschrift from "Johannes Norbertus Kroon" at "Technische Universiteit Eindhoven". The document refers to tools for blind people in general, and contains some details on the MEA8000 chip.
* Interresting is that Noise seems to be generated by some ADD/MULTIPLY operations.
* And, the Normalization (N) stuff implies that there are some (Normalization, means what... Floating Point? Saturation? Interpolation?) adjustments done at various different locations.
