摘要

An apparatus for determining an estimated pitch lag is provided. The apparatus comprises an input interface (1 10) for receiving a plurality of original pitch lag values, and a pitch lag estimator (120) for estimating the estimated pitch lag. The pitch lag estimator (120) is configured to estimate the estimated pitch lag depending on a plurality of original pitch lag values and depending on a plurality of information values, wherein for each original pitch lag value of the plurality of original pitch lag values, an information value of the plurality of information values is assigned to said original pitch lag value.
