An audio encoding/decoding method and apparatus to reproduce a high quality audio signal without losing a high frequency band using time-scale compression/expansion. The method includes encoding an input audio signal into audio data by determining a similarity between frames of the input audio signal, compressing the input audio signal with respect to a time-scale, generating a frame time-scale modification flag, and decoding the audio data of the encoded audio signal based on the frame time-scale modification flag.
