摘要: The present invention relates to digital audio coding systems that employ high freuqency reconstruction (HFR) methods. It teaches how improve the overall perforamcne of such systems, by means an adaptation over time crossover frequency between lowband coded a core codec, and highband HFR system. Different methods establishing instantaneous optimum choice are introduced.
