| Zusammenfassung: | An audio encoding device capable of efficient encoding processing includes: a storage unit which stores audio data; a data acquisition controller which acquires the audio data from the storage unit; a transformation unit which processes an audio data signal outputted from the data acquisition unit for frequency transformation; a harmonic overtone generation/synthesizing unit which generates a harmonic based on a first output wave out of an output wave of the transformation unit and synthesizes the harmonic and a second output wave out of the output wave of the transformation unit, the second output wave being higher in frequency than the first output wave; and an encoder which subjects an output from the harmonic overtone generation/synthesizing unit to encoding processing. |
