Abstract:
An audio signal, having first and second regions of frequency spectrum, is coded. Spectral peaks in the first region are encoded by a first coding method. For a segment of the audio signal, a relation between energy of bands in the first and second regions 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. Responsive to first and second relations fulfilling a respective predetermined criterion and a sufficient number of bits, encoding the band in the second region using a second coding method different from the first coding method, and otherwise, subjecting the band in the second region to BandWidth Extension BWE or noise fill.

Claim (Index 1):
A method for encoding an audio signal, wherein a frequency spectrum of the audio signal is divided into at least a first and a second region, wherein at least the second region comprises a number of bands, the method comprising:\n encoding spectral peak segments in the first region using a first coding method; encoding at least one non-peak segment in the first region using a second coding method different from the first coding method; determining a first relation between an energy of a band in the second region and energies of the spectral peaks in the first region; determining a second relation between the energy of the band in the second region and an average energy of the second region; determining an available number of bits is sufficient for encoding the band in the second region; responsive to determining the first and second relations fulfil a predetermined criterion and determining the number of bits is sufficient, encoding the band in the second region using the second coding method.
