The method also includes generating, at a decoder of the first device, a low-band excitation signal from the bit-stream. The method also includes generating a first baseband signal at a high-band excitation generator of the decoder. Generating the first baseband signal includes performing a spectral flip operation on a nonlinearly transformed version of the low-band excitation signal, and the first baseband signal corresponds to a first sub-band of a high-band portion of an audio signal received at the second device. The method also includes generating a second baseband signal corresponding to a second sub-band of the high-band portion of the audio signal. The method also includes outputting at least a partially reconstructed version of the audio signal based at least in part on the first baseband signal and the second baseband signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-band signal coding using multiple sub-bands","description":"A method includes receiving, at a first device, a bit-stream from a second device.
