  • METHOD OF ENCODING AUDIO SIGNAL AND ENCODER, METHOD OF DECODING AUDIO SIGNAL AND DECODER
    Publication number: 20230230604
    Abstract: A method of encoding an audio signal and an encoder and a method of decoding an audio signal and a decoder are provided. The method of encoding an audio signal includes outputting a decoded signal by using a bitstream that encodes an audio signal, separating the decoded signal into a low-band signal and a high-band signal by using a sound source separator, upsampling the low-band signal, upsampling the high-band signal, and restoring the audio signal by synthesizing the upsampled low-band signal with the upsampled high-band signal, wherein the bitstream is generated by encoding a superimposed signal in which a signal in a high frequency band of the audio signal is superimposed on a low frequency band of the audio signal.
