Hi !

I want to learn more about different representations
of the LP coefficients (ie reflection coefficients, spectral
frequency line, and so on). How to transform between those
representations and what they actually mean.

I'm searching for an easy representation which is robust
against quantization and also allows the signal to be
losslessly coded. (It should be easy to calculate the LP
coefficients in a 100% deterministic manner using integer
arithmetic)

I would appreciate recommendations for articles/books that
focus on this topic (preferably free/online) or any other
advice.


Thanks!
Sebastian

Two common ways I know of are LAR(Log Area Ratios) and LSP(Line
spectral frequencies). I read from the Low Bitrate Speech
Communication Book by Kondoz.
