摘要： This invention is aimed at providing an encoding-signal-processing method and a device thereof that are able to compress and restore an audio signal at higher efficiency. For the aim of the invention, the disclosed audio-signal-processing method is characterized by comprising the steps of: judging based on primary information whether or not an audio signal type is a music signal; if not, judging based on secondary information whether the audio signal type is a voice signal or a mixed signal; and restoring the audio signal according to a coding method applied to each frame by using coding identification information when the audio signal type is a music signal, a voice signal or a mixed signal. Only the first type information is received if the audio signal type is a music signal, and both the primary information and the secondary information are received if the audio signal type is a voice signal or a mixed signal. Therefore, various audio signals can be encoded and decoded at higher efficiency.

摘要： Encoding and decoding apparatuses and encoding and decoding methods are provided. The decoding method includes extracting a plurality of encoded signals from an input bitstream, determining which of a plurality of decoding methods is to be used to decode each of the encoded signals, decoding the encoded signals using the determined decoding methods, and synthesizing the decoded signals. Accordingly, it is possible to encode signals having different characteristics at an optimum bitrate by classifying the signals into one or more classes according to the characteristics of the signals and encoding each of the signals using an encoding unit that can best serve the class where a corresponding signal belongs. In addition, it is possible to efficiently encode various signals including audio and speech signals.
