APPARATUS AND METHOD FOR ENCODING AND DECODING OF INTEGRATED SPEECH AND AUDIO

WIPO Patent Application WO/2010/008179

A1

Provided are an apparatus and a method for integrally encoding and decoding a speech signal and a audio signal. The encoding apparatus (100) may include: an input signal analyzer (110) to analyze a characteristic of an input signal; a first conversion encoder (120) to convent the input signal to a frequency domain signal, and to encode the input signal when the input signal is a audio characteristic signal; a Linear Predictive Coding (LPC) encoder (130) to perform LPC encoding of the input signal is a speech characteristic signal; and a bit-stream generator (140) to generate a bit-stream using an output signal of the first conversion encoder (120) and an output signal of the LPC encoder (130).
