摘要
A voice and audio signal encoding/decoding apparatus and a method thereof are provided to efficiently and simultaneously encode/decode voice and audio signals. A signal separation part(110) separates an input signal into signals having different frequency bands. A phase and amplitude information extracting unit(120) extracts momentary phase and momentary amplitude information of each of the separated signal by performing Hilbert conversion of the separated signal. An encoder(130) encodes each of the separated signal by using the extracted momentary phase and momentary amplitude information.
