Log Area Ratios
From Wikipedia, the free encyclopedia
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 rk 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 codecs, such as GSM-FR use LARs.
