Abstract: [Problem] To provide an audio device with which it is possible to efficiently utilize the storage capacity of a storage device for storing audio data. [Solution] In this audio device 1, in accordance with user profile information stored in a profile information storage unit 102, audio data inputted to an audio data input unit 103 is subjected by a filter unit 104 to a process of cutting a frequency band higher than the highest frequency audible to the user) and/or a frequency band lower than the lowest frequency audible to the user, and the data is then encoded by a codec unit 105, and stored to an audio storage device 100. Audio data can thereby be stored in the audio storage device 100 in compressed form with no noticeable decline in sound quality to the user, making it possible to store more audio data, such as music, in the audio storage device 100.
