An input signal includes a channel-based audio signal and an object-based audio signal, and an audio encoding device includes an audio scene analysis unit configured to determine an audio scene from the input signal and detect audio scene information; a channel-based encoder that encodes the channel-based audio signal output from the audio scene analysis unit; an object-based encoder that encodes the object-based audio signal output from the audio scene analysis unit; and an audio scene encoding unit configured to encode the audio scene information.
