A playout delay adjustment method includes: adjusting a playout delay surplus based on a difference value between a first playout delay obtained in a first scheme and a second playout delay obtained in a second scheme and determining an adaptation type of a current frame according to whether a previous frame is an active frame; and when the determined adaptation type is signal-based adaptation, performing time scale modification (TSM) according to an adaptation scheme determined according to a comparison result between the first playout delay and the second playout delay and a comparison result between a target delay and the first playout delay.

A method of generating a wideband signal may include estimating a high-band spectrum parameter from a reconstructed narrowband signal based on a combination of at least two mapping schemes; estimating a high-band excitation signal based on the reconstructed narrowband signal; generating a high-band signal based on the estimated high-band spectrum parameter and the estimated high-band excitation signal; and generating a wideband signal by synthesizing the reconstructed narrowband signal with the high-band signal.
