Abstract
THE APPLICATION RELATES TO AUDIO ENCODING AND DECODING. IN ORDER TO ENHANCE CODED AUDIO SIGNALS, THERE IS PROVIDED DIVIDING THE AUDIO SIGNAL INTO AT LEAST A LOW FREQUENCY BAND AND A HIGH FREQUENCY BAND, DIVIDING THE HIGH FREQUENCY BAND INTO AT LEAST TWO HIGH FREQUENCY SUB-BAND SIGNALS, AND GENERATING PARAMETERS THAT REFER AT LEAST TO THE LOW FREQUENCY BAND SIGNAL SECTIONS, WHICH MATCH BEST WITH HIGH-FREQUENCY SUB-BAND SIGNALS.
Audio encoder, audio decoder, method for providing an encoded audio information, method for providing a decoded audio information, computer program and encoded representation using a signal-adaptive bandwidth extension
Decoder for generating a frequency enhanced audio signal, method of decoding, encoder for generating an encoded signal and method of encoding using compact selection side information
