Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Referring to Fig. 1, be the method for making process flow diagram of the described word for word synchronized lyrics of embodiment of the invention file.As shown in Figure 1, the method comprising the steps of:
S101: load audio file, extract the voice data and the temporal information of described audio file;
S102: according to the temporal information of audio file, the rise time axle;
S103: according to the voice data of audio file, corresponding described time shaft generates the audio volume control figure of described audio file and shows;
S104: obtain the lyrics of described audio file, determine that each literal is corresponding to the initial position and the demonstration of described time shaft in the lyrics;
S105: drag handle for each literal in the lyrics generates the lyrics;
S106: displaying audio file, and on audio volume control figure, point out playing progress rate;
S107: receive the user the described lyrics are dragged the request that the handle position is adjusted, the position that the described lyrics is dragged handle is adjusted; Drag the relative position of each point on handle and the described time shaft according to the adjusted described lyrics, determine the temporal information of each word in the lyrics;
S108: preserve the temporal information of each word in the lyrics after determining, generate word for word synchronized lyrics file.
Among the step S101, the audio file of loading can be various forms, for example MP3, WMA, APE or the like.After the loading, adopt corresponding demoder to extract the voice data and the temporal information of described audio file.Wherein temporal information specifically can be the time span of audio file.
Among the step S102, the time shaft of generation can show on user interface.
The audio volume control figure that generates among the step S103, the temporal information of each literal provides visual reference frame in the lyrics for the user adjusts.
Concrete, with reference to Fig. 2, for adopting a kind of software interface synoptic diagram of the described method of the embodiment of the invention.Usually, in an audio file, the singer sings the sound big (because like this could give prominence to voice, make hearer hear the clearly lyrics) of the sound of the lyrics than accompaniment.Therefore, the amplitude of singing the audio volume control of lyrics part can be bigger than the amplitude of accompaniment audio volume control partly, forms a vibration more significantly.That is to say that each word corresponding audio waveform roughly can form a kind of like this vibration: this vibration and accompaniment oscillating phase ratio partly, amplitude is bigger, relatively significantly; And each vibration all is to be starting point with less amplitude, begins then to increase gradually, reduces gradually after reaching peak value again, finishes with less amplitude; Wherein, each vibration initial and finish the initial and end of just corresponding the lyric characters of singing.Therefore, utilize this characteristics, just can determine the initial and concluding time of the corresponding lyric characters of singing according to the initial and end position of each vibration on the audio volume control figure.
In addition, need to prove that there is corresponding relation in the audio volume control figure that generates among the step S103 with the time shaft of audio file.Any place's audio volume control all has corresponding with it time zone on the audio volume control figure on time shaft.
Among the step S104, obtaining the lyrics of described audio file, can be to obtain the manually lyrics of input of user, also can load the lyrics in the existing lyrics file.
When obtaining the user manually during the lyrics of input: can an initial value be set, for example 1 second to the duration of each word of input.Can be with first word acquiescence corresponding between 0 second to 1 second of audio file, second word is corresponding between 1 second to 2 seconds of audio file, and the rest may be inferred.When the input lyrics number of words more for a long time, can adjust the duration of each word, the principle of adjustment is: the summation of the duration of all literal is no more than the time span of this audio file in the lyrics.
When loading the lyrics in the existing lyrics file: existing lyrics file can be the file that common suffix is called the .1rc type.Usually this existing lyrics file is sentence by sentence synchronous, also, has included the temporal information of the lyrics in this lyrics file, and only this temporal information is only at every lyrics.
In order to make full use of the temporal information in the existing file of synchronized lyrics sentence by sentence, the described method of the embodiment of the invention also comprises: parse every lyrics time corresponding in the described lyrics file of loading; Determine that according to every lyrics time corresponding in the described lyrics file each literal is corresponding to the initial position and the demonstration of described time shaft in the lyrics.
Wherein, every lyrics time corresponding comprises the zero-time and the concluding time of these lyrics in the described lyrics file that parses.Determine that according to every lyrics time corresponding in the described lyrics file each literal is corresponding to the initial position and the demonstration of described time shaft in the lyrics, specifically can be: deduct the duration that described zero-time obtains these lyrics with the described concluding time, divided by the literal number of these lyrics, obtain the average duration of each word; In conjunction with the zero-time of these lyrics, can calculate the expectation zero-time and the expected concluding time of each literal in these lyrics successively; In lyrics viewing area, show each literal.The viewing area of each literal wherein is corresponding to the expectation duration scope (being the expectation zero-time of this literal on the time shaft and the scope between the expected concluding time) of this literal on the time shaft.
After loading the existing file of synchronized lyrics sentence by sentence, can also and finish word according to the banner word in every the lyrics of every lyrics time corresponding identification that parse, to the banner word in every lyrics with finish word, distinguish demonstration, with the described lyrics in other literal distinguish mutually.Concrete, the font size of banner word in every lyrics and end word can be adjusted, use than the big font of other literal in these lyrics, show banner word and finish word; Also can and finish word with the banner word in every lyrics, use with these lyrics in the different color of other literal, show.
Among the step S105,, each literal in the lyrics drags handle for generating the lyrics.Each literal can correspond respectively to two described lyrics and drag handle, to determine the zero-time and the concluding time of each word respectively.Concrete, the lyrics drag the position of handle and there is corresponding relation in the time point on the time shaft.As shown in Figure 2, it is corresponding with the zero-time of this word that the lyrics on each literal left side drag handle, and it is corresponding with the concluding time of this word that the lyrics on the right drag handle.Can regulate the zero-time or the concluding time of corresponding word by adjusting position that the lyrics drag handle.
Among the step S105, also can be only drag handle corresponding to the lyrics of the zero-time of this literal for each literal generation.In this case, the lyrics between two adjacent words drag handle, except the zero-time of that word of expression back, also represent the concluding time of before word.
The difference of the lyrics file that two kinds of situations generate is, the former is for the demonstration time of each word in the lyrics, represents that this literal should sing in the demonstration time; The latter is for the demonstration time of each word in the lyrics, except representing the singing time of this literal, may represent also that this word is sung to finish, but next word do not begin that section accompaniment time of singing as yet.
The method for making of the described word for word synchronized lyrics of embodiment of the invention file, can also and finish word according to the banner word in every the lyrics of every lyrics time corresponding identification that parse, the lyrics to banner word in every lyrics and end word drag handle, distinguish demonstration, with the described lyrics in the lyrics of other literal drag handle and distinguish mutually.For example: the banner word in every lyrics and the lyrics that finish word are dragged the color of handle, be arranged to drag the different color of handle with the lyrics of other word; Perhaps the lyrics of banner word in every lyrics and end word are dragged the shape of handle, be arranged to drag the different shape of handle with the lyrics of other word.
Among the step S106, the method for prompting playing progress rate on audio volume control figure can be to adopt the playing progress rate pointer to point out on audio volume control figure, also can be to adopt the part of broadcast corresponding on the different colour code audio volume control figure and do not play part.
Wherein, the playing progress rate pointer can be the vertical line (can certainly be other shapes) on audio volume control figure.This playing progress rate pointer position on audio volume control figure indicates where this audio file has played to.The user can also drag this playing progress rate pointer, to adjust the playing progress rate of audio file.Adopt the part of broadcast corresponding on the different colour code audio volume control figure and do not play part, for instance: can be designated green with having play part on the audio volume control figure, not play part and be designated redness.
In addition, adopt playing progress rate pointer and the method that adopts these two kinds prompting playing progress rates on audio volume control figure of different colour codes, can use separately, also can use simultaneously.
As from the foregoing, the preferred embodiment of the method for making of word for word synchronized lyrics file of the present invention as shown in Figure 3, comprises step:
S201: load audio file, extract the voice data and the temporal information of described audio file;
S202: according to the temporal information of audio file, the rise time axle;
