The method includes extracting from the encoded audio bitstream a first waveform-coded signal including spectral coefficients corresponding to frequencies up 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 is above the first cross-over frequency and the parametric decoding uses reconstruction parameters derived from the encoded audio bitstream to generate the reconstructed signal. The method further includes extracting from the encoded audio bitstream a second waveform-coded signal including spectral coefficients corresponding to a subset of frequencies above the first cross-over frequency and interleaving the second waveform-coded signal with the reconstructed signal to produce an interleaved signal. The interleaved signal is then combined with the first waveform-coded signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio decoder for interleaving signals","description":"A method for decoding an encoded audio bitstream in an audio processing system is disclosed.
