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 -- PGP-Key-ID (long): 572B1778A4CA0707

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.
