LPC RESIDUAL SIGNAL ENCODING/DECODING APPARATUS OF MODIFIED DISCRETE COSINE TRANSFORM (MDCT)-BASED UNIFIED VOICE/AUDIO ENCODING DEVICE |
摘要 |
Disclosed is an LPC residual signal encoding/decoding apparatus of an MDCT based unified voice and audio encoding device. The LPC residual signal encoding apparatus analyzes a property of an input signal, selects an encoding method of an LPC filtered signal, and encode the LPC residual signal based on one of a real filterbank, a complex filterbank, and an algebraic code excited linear prediction (ACELP). |

1. A processing method, comprising:
identify a first block included in a previous frame; identify a second block included in a current frame; identifying an intentional signal related to the first block; and overlap-adding the first block and second block using a window applied to the intentional signal, wherein the first block has a speech characteristic and the second block has audio characteristic. |
