摘要: A decoder for generating a frequency enhanced audio signal (120), comprises: feature extractor (104) extracting from core (100); side information (110) selection associated with the signal; parameter generator (108) parametric representation estimating spectral range of (120) not defined by (100), wherein is configured to provide number alternatives (702, 704, 706, 708) in response (112), and select one as (712 718); estimator (118) using selected.
