Claim:
1. A method for scalably encoding an input audio/speech signal, the method comprising: encoding, performed by using at least one processing device, a core layer signal associated with a core bandwidth, from the input audio/speech signal; encoding, performed by using at least one processing device, one or more enhancement layer signal associated with one or more extended bandwidth, respectively, from the input audio/speech signal; generating a bitstream by multiplexing the encoded core layer signal and the one or more encoded enhancement layer signal; and transmitting the bitstream to a decoding side, wherein the encoding one or more enhancement layer signal comprises: obtaining one or more extension signal from the core bandwidth and the one or more extended bandwidth; transforming the one or more extension signal from a time domain into a frequency domain; and generating the one or more encoded enhancement layer signal by encoding the one or more transformed extension signal.
