Hi, we've done some work to our 'Spectral Estimation Toolbox' and added Burg's algorithm for spectral estimation. It's all on CGRAN, see https://www.cgran.org/wiki/SpecEst
Things aren't 100% perfect, probably due to the high number of multiplications numerical accuracy is sometimes a bit off when compared to Matlab and Octave (which are quite different themselves!), but it works nicely so far when all you want to do is estimate spectra. One of our students rigged a demo in which a narrow-band signal was nicely tracked by the algorithm; I'll hopefully add that soon along with GRC bindings.
