摘要: Methods and apparatus for performing signal processing. The processing comprises demultiplexing input encoded data into including information a segment frames coefficient selected in the of segment, low band data, decoding to produce signal, selecting frame be processed from plurality coefficients based on calculating high sub-band power each constituting coefficient, producing signal.
