Such as, when the user is provided with volume value at needs at least one audio file, can pass through dual mode:
1) in the audio file playing process, through volume key or option is set, volume value is provided with.At this moment, setting is the volume value of the playback frequency file broadcast.
2) when the audio file tabulation was perhaps browsed audio file, the user can select audio file wherein, through particular option " volume setting " selected audio file volume is set again.
It should be noted that; In aforesaid way, mode 2) can carry out the setting of audio file cohort volume value, promptly be to carry out the cohort setting according to the music type of audio file; Such as, can carry out the classification setting volume according to different music types such as rock music, pop music or light musics.Certainly, the music type of audio file all can obtain from the corresponding label frame of this audio file.
When the user need be provided with volume value, promptly can send at least one audio file volume value instruction is set, step S11 promptly obtains this at least one audio file volume value instruction is set.
Step S12, the volume value of at least one audio file is preserved in instruction according to volume value.
Such as, this volume value can be a concrete numerical value, also can be a scope.Volume value directly is stored in the audio file, perhaps is stored in the CONFIG.SYS.
Step S13 resolves audio file and obtains its volume value.
When volume value directly is stored in the audio file, resolves audio file, and therefrom obtain volume value; When volume value is stored in the CONFIG.SYS; From CONFIG.SYS, obtain volume value; And still need resolve audio file, because the sound that the user heard preserves with certain data layout, so when displaying audio file, should decode to audio file.
Step S14 is according to the volume value displaying audio file.
Such as, if volume value is a concrete numerical value, during playing back music, play according to this volume value; Perhaps volume value is a scope, when displaying audio file, if the volume value of CONFIG.SYS acquiescence in this scope, is play according to the volume value of CONFIG.SYS acquiescence; If the volume value of CONFIG.SYS acquiescence is play according to minimum, the highest or mean value that satisfies volume range, look the user preferences decision here not in this scope.
The embodiment of the invention combines the mode of preserving through adopting with volume value and at least one audio file, can make the broadcast sound volume of different audio files all be positioned at desirable scope, and not need frequent setting, makes things convenient for the user, improves user experience.
Consult Fig. 2, Fig. 2 is the process flow diagram of sound-volume management method second embodiment of the present invention.The embodiment of the invention comprises the steps:
Step S21 obtains at least one audio file volume value instruction is set.
Step S22 carries out encoding process to volume value, and the volume value after encoding process directly is kept in the label frame of at least one audio file.
Step S23 resolves at least one audio file, from the label frame of at least one audio file, obtains volume value.
Step S24 is according to the volume value displaying audio file.
In the embodiment of the invention, audio file is that example describes with the MP3 music file, and the enforcement principle of step S22 is following:
The MP3 music file is to be made up of frame (frame), and frame is that the minimum of MP3 music file is formed unit.Every frame all comprises frame head, and can calculate the length of frame.According to the different in kind of frame, the MP3 music file mainly divides can be three parts, TAG_V2 (ID3v2) label frame, Frame and TAG_V1 (ID3v1) label frame.Be not that each mp3 file all has ID3v2, but must have Frame and ID3v1 frame in each MP3 music file.ID3v1 is mark at EOF with character string " TAG ", and its length is 128 bytes of fixing, and has wherein comprised information such as title of the song, singer's name, album--name and the time of producing.Owing to all have ID3v1 in each MP3 music file, therefore, among the present invention volume value also be stored in this partial data.The data result of ID3v1 is as shown in the table:
| Byte number | Content |
| 1 to 3 | Tag head must be " TAG " |
| 4 to 33 | Song title |
| 34 to 63 | Singer's title |
