摘要:A method for decoding an encoded audio bitstream in an audio processing
system is disclosed. The method includes extracting from the encoded audio bitstream afirst waveform-coded signal including spectral coefficients corresponding to frequenciesup to a first cross-over frequency and performing parametric decoding at a second cross-over frequency to generate a reconstructed signal. The second cross-over frequency isabove the first cross-over frequency and the parametric decoding uses reconstructionparameters derived from the encoded audio bitstream to generate the reconstructedsignal. The method further includes extracting from the encoded audio bitstream asecond waveform-coded signal including spectral coefficients corresponding to a subsetof frequencies above the first cross-over frequency and interleaving the secondwaveform-coded signal with the reconstructed signal to produce an interleaved signal.The interleaved signal is then combined with the first waveform-coded signal.
