Spectral peaks in the first region are encoded by a first coding method. For a segment of the audio signal, a relation between an energy of a band in the second region and an energy estimate of the first region is determined. A relation between the energy of the band in the second region and energy of neighboring bands in the second region is determined. A determination is made whether available bits are sufficient for encoding at least one non-peak segment of the first region and the band in the second region. Further, when the relations fulfill a respective criterion and the bits are sufficient, the band in the second region and the at least one segment of the first region are encoded using a second coding method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio coding method and apparatus","description":"An audio signal is coded, where a frequency spectrum of the audio signal is divided into first and second regions.
