METHOD OF ENCODING/DECODING AUDIO SIGNAL AND DEVICE FOR PERFORMING THE SAME

This abstract first appeared for US patent application 18732758 titled 'METHOD OF ENCODING/DECODING AUDIO SIGNAL AND DEVICE FOR PERFORMING THE SAME



Original Abstract Submitted

A method of encoding/decoding an audio signal and a device for performing the same are provided. The method of encoding an audio signal includes generating, based on the audio signal, a linear prediction coding (LPC) bitstream and a frequency-domain signal of the audio signal, generating, based on the LPC bitstream and the frequency-domain signal, a first residual signal including information on a frequency envelope of the frequency-domain signal, and outputting a second residual signal by processing a first residual signal through one of a plurality of signal processing paths.
