AUDIO ENCODER, AUDIO DECODER, METHOD FOR ENCODING AN AUDIO SIGNAL AND METHOD FOR DECODING AN ENCODED AUDIO SIGNAL

摘要

An encoder for encoding an audio signal. The encoder is configured to encode the audio signal in a transform domain or filter-bank domain, wherein the encoder is configured to determine spectral coefficients of the audio signal for a current frame and at least one previous frame, wherein the encoder is configured to selectively apply predictive encoding to a plurality of individual spectral coefficients or groups of spectral coefficients which are separated by at least one spectral coefficient.
