Hello Daniel, Bringing non-DSP people up to speed with Codec 2 is an area I am also interested in. Part of the Open Source/Ham ethic is to educate. The sections in that paper on LPC, MELP, and AMBE are relevant to Codec 2.
I have also started experimenting with graphical ways to describe the DSP in Codec 2 - see my recent lca.conf.au 2012 Video. I have also blogged on various parts of the algorithm (mainly non-mathematical), and there is also my thesis (mathematical). I would be interested to hear what others on the list would like to hear re explaining Codec 2.
