Apparatus for coding of variable bitrate wideband speech and audio signals, and a method thereof |
摘要 |
Disclosed is an apparatus for coding of variable bitrate wideband speech and audio, comprising: a) a speech and audio divider for dividing signals inputted to a CODEC into speech or audio signals; b) a narrowband coder for performing narrowband coding, in the case the divided input signals are speech signals; c) a bitrate modifier for modifying a bitrate for coding of a low frequency band and a bitrate for coding of a high frequency band, in the case the divided input signals are audio signals; and d) a wideband coder for performing coding by the modified bitrate in the bitrate modifier.
