Abstract: Disclosed are encoding and decoding apparatuses and methods based on variable sub-band analysis. The encoding method based on variable sub-band analysis includes: generating down-mixed signals out of inputted multiple audio objects and encoding the down-mixed signals; transforming the multiple audio objects into a frequency domain to thereby produce frequency-domain signals; dividing a sub-band of the frequency-domain signals into variable sub-bands based on a characteristic of the sub-band and generating variable sub-band information including information on the variable sub- bands; generating parameter information used for recovering the down-mixed signals based on the variable sub-bands; and encoding the variable sub-band information and the parameter information.
