Registered METHOD AND APPARATUS FOR ENCODING AND DECODING AUDIO SIGNAL USING ADAPTIVE SINUSOIDAL PULSE CODING

Project Code: 08MC3400, Study on Acoustic Convergence Codec and its Control Technology for FMC, Lee Byung Sun

Abstract: A method and an apparatus for encoding and decoding audio signals using adaptive sinusoidal coding are provided. The audio signal encoding method includes the steps of dividing a synthesized audio signal into a plurality of sub-bands, calculating the energy of each sub-band, selecting a predetermined number of sub-bands having a relatively large amount of energy from the sub-bands, and performing sinusoidal coding with regard to the selected sub-bands. Application of sinusoidal coding based on consideration of the amount of energy of each sub-band of the synthesized signal improves the quality of the synthesized signal more efficiently.
