obtaining at least a part of the audio file under the established reproducing mode; and determining whether the audio file is reproducible under the established reproducing mode by checking whether the part of the audio file constructs a specific format stream corresponding to the applied reproducing mode. ## Claims ### Claim 1 A method of reproducing an audio file, comprising: applying a reproducing mode established based on an attribute information; obtaining at least a part of the audio file under the established reproducing mode; and determining whether the audio file is reproducible under the established reproducing mode by checking whether the part of the audio file constructs a specific format stream corresponding to the applied reproducing mode. ### Claim 2 (depends on 1) The method of claim 1, wherein the attribute information includes an extension information of the audio file separated from but associated with audio data of the audio file. ### Claim 3 (depends on 1) The method of claim 1, wherein the reproducing mode is a mode for decoding the audio file. ### Claim 4 (depends on 1) The method of claim 1, further comprising automatically changing the reproducing mode into another reproducing mode if the audio file is not reproducible under the established reproducing mode. ### Claim 5 (depends on 1) The method of claim 1, wherein the part of audio file is a part of a header in the audio file. ### Claim 6 (depends on 1) The method of claim 1, further comprising skipping the audio file if the audio file is not reproducible under the established reproducing mode. ### Claim 7 (depends on 1) The method of claim 1, further comprising controlling for continuously reproducing audio files reproducible under the established reproducing mode. ### Claim 8 (depends on 1) The method of claim 1, further comprising controlling for selectively reproducing audio files reproducible under the established reproducing mode. ### Claim 9 (depends on 1) The method of claim 1, further comprising displaying information including at least title information of a current reproduced audio file. ### Claim 10 An apparatus for reproducing an audio file, comprising: a mode establishing controller configured to establish a reproducing mode based on an attribute information; a reader configured to obtain at least a part of the audio file under the established reproducing mode; and a checking controller configured to determine whether the audio file is reproducible under the established reproducing mode by checking whether the part of the audio file constructs a specific format stream corresponding to the applied reproducing mode. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the attribute information includes an extension information of the audio file separated from but associated with audio data of the audio file. ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the mode establishing controller is configured to establish the reproducing mode decoding the audio file. ### Claim 13 (depends on 10) The apparatus of claim 10, wherein the mode establishing controller is configured to automatically change the reproducing mode into another reproducing mode if the audio file is not reproducible under the established reproducing mode. ### Claim 14 (depends on 10) The apparatus of claim 10, wherein the part of audio file is a part of a header in the audio file. ### Claim 15 (depends on 10) The apparatus of claim 10, wherein the apparatus is configured to skip the audio file if the audio file is not reproducible under the established reproducing mode. ### Claim 16 (depends on 10) The apparatus of claim 10, further comprising a reproducing controller configured to control continuously reproducing audio files reproducible under the established reproducing mode. ### Claim 17 (depends on 10) The apparatus of claim 10, further comprising a reproducing controller configured to control selectively reproducing audio files reproducible under the established reproducing mode. ### Claim 18 (depends on 10) The apparatus of claim 10, further comprising a display configured to display information including at least title information of a current reproduced audio file. ### Claim 19 An apparatus for reproducing an audio file, comprising: a reader configured to read the audio file; and a controller configured to establish a reproducing mode based on an attribute information, determine whether the audio file is reproducible under an established reproducing mode by checking whether a part of the audio file constructs a specific format stream corresponding to an applied reproducing mode, and control the reader to reproduce the corresponding audio file in response to the determination. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the attribute information includes an extension information of the audio file separated from but associated with audio data of the audio file. ### Claim 21 (depends on 19) The apparatus of claim 19, wherein the controller is configured to establish the reproducing mode for decoding the audio file. ### Claim 22 (depends on 19) The apparatus of claim 19, wherein the controller is configured to automatically change the reproducing mode into another reproducing mode if the audio file is not reproducible under the established reproducing mode. ### Claim 23 (depends on 19) The apparatus of claim 19, wherein the part of audio file is a part of a header in the audio file. ### Claim 24 (depends on 19) The apparatus of claim 19, wherein the controller is configured to control the reader to skip the audio file if the audio file is not reproducible under the established reproducing mode. ### Claim 25 (depends on 19) The apparatus of claim 19, wherein the controller is further configured to control continuously reproducing of audio files reproducible under the established reproducing mode. ### Claim 26 (depends on 19) The apparatus of claim 19, wherein the controller is further configured to control selectively reproducing audio files reproducible under the established reproducing mode. ### Claim 27 (depends on 19) The apparatus of claim 19, further comprising: a display unit configured to display information including at least title information of a current reproduced audio file.
