Abstract

Methods, an encoder and a decoder are configured for transition between frames with different internal sampling rates. Linear predictive (LP) filter parameters are converted from a sampling rate Sto a sampling rate S. A power spectrum of a LP synthesis filter is computed, at the sampling rate S, using the LP filter parameters. The power spectrum of the LP synthesis filter is modified to convert it from the sampling rate Sto the sampling rate S. The modified power spectrum of the LP synthesis filter is inverse transformed to determine autocorrelations of the LP synthesis filter at the sampling rate S. The autocorrelations are used to compute the LP filter parameters at the sampling rate S
