摘要
Disclosed is an apparatus for encoding/decoding an LPC residual signal of an MDCT-based voice/audio integrated encoder. The LPC residual signal encoding apparatus analyzes characteristics of an input signal to select an encoding method of an LPC-filtered signal, and includes a real filterbank, a complex filterbank, and ACELP (Algebraic code excited linear prediction). The LPC residual signal is encoded based on one of.
