“Linear prediction based audio encoder and decoder, methods for encoding and decoding linear prediction based audio and computer program” summary linear prediction based audio encoding is enhanced by encoding a spectrum composed of a plurality of spectral components using a probability distribution estimation determined for each of the plurality of spectral components from linear prediction coefficient information. in particular, linear prediction coefficient information is available anyway. therefore, it can be used to determine the probability distribution estimation on both coding and decoding sides. The latter determination can be implemented in a computationally simple manner using, for example, appropriate parameterization for estimating the probability distribution in the plurality of spectral components. All in all, the coding efficiency as provided by entropy coding is compatible with probability distribution estimates as achieved using context selection, but its derivation is less complex. for example, the derivation may be purely analytically and / or does not require any information about neighborhood spectral line attributes such as previously encoded / decoded spectral values of neighborhood spectral lines as is the case in spatial context selection. 1/1
