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 31):
The apparatus of  claim 16 , wherein the apparatus is further configured to perform operations comprising:\n responsive to determining the first and second relations do not fulfil the predetermined criterion or determining the available number of bits is not sufficient for encoding the band in the second region, transmitting parameters toward a decoding apparatus to subject the band in the second region to BandWidth Extension BWE or noise fill during decoding.
