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.
