FRAME LOSS RECOVERING METHOD, AND AUDIO DECODING METHOD AND DEVICE USING SAME

Document Type and Number:

WIPO Patent Application WO/2014/042439

Kind Code:

A1

Abstract:

The present invention relates to a frame recovering method, and to an audio decoding method and to an apparatus using same. The frame loss recovering method of an audio signal includes the steps of: grouping, into a predetermined number of bands, conversion coefficients of at least one frame from among frames preceding a current frame; inducing an attenuation constant according to the tonal degrees of the grouped bands; and recovering conversion coefficients of the current frame by applying the attenuation constant to the frame preceding the current frame.
