Decoder and encoder for energy in bandwidth extension

Encoder (10) for coding a signal comprising a band-limited signal and an extended-band signal, the encoder (10) comprising: a calculator (12) configured to perform energy prediction of the extended-band signal based on LPC coefficients; and a coder (14) configured to encode a residual of the signal using the energy prediction and an offset (o); wherein the offset (o) is dependent on a bit-rate.
