METHOD AND APPARATUS FOR DETERMINING ENCODING MODE, METHOD AND APPARATUS FOR ENCODING AUDIO SIGNALS, AND METHOD AND APPARATUS FOR DECODING AUDIO SIGNALS

摘要

Provided is a method for determining an encoding mode comprising the steps of: determining one of a plurality of encoding modes including a first encoding mode and a second encoding mode as an initial encoding mode of the current frame in correspondence to the characteristics of an audio signal; and modifying, if an error exists in the determination of the initial encoding mode, the initial encoding mode into a third encoding mode so as to generate a modified encoding mode.
