Log area ratio coefficients
Log area ratios (LAR) can be used to represent reflection coefficients (another form for linear prediction coefficients) for transmission over a channel. While not as efficient as line spectral pairs (LSPs), log area ratios are much simpler to compute. Let be the kth reflection coefficient of a filter, the kth LAR is: Use of Log Area Ratios have now been mostly replaced by Line Spectral Pairs, but older codec… Witryna1 sty 2004 · Log area ratio coefficients (LAR) derived from linear prediction coefficients (LPC) is a well known feature extraction technique used in speech applications.
