Specific implementation mode
Referring to Fig. 1, Fig. 1 is the flow diagram of one embodiment of the tone line generation method of the present invention.This implementation
In example, tone line generation method includes：
101, note information sequence is obtained, each note information includes note height in the note information sequence.
There are many ways to obtaining note information sequence.For example, in practical application, the note information of song is stored in
MIDI (English：Musical Instrument Digital Interface, Chinese：Musical instrument digital interface) in file.
MIDI is the electronic communication protocol of an industrial standard, be the performance apparatus (such as synthesizer) such as electronic musical instrument define various notes or
Play code.After getting the MIDI files of song, parsed from the MIDI files in the song at the beginning of each note
Between, end time (or duration) and note height.Specifically, note height is normally in section [21,108].Solution
At the beginning of each note is precipitated, after end time (or duration) and note height, a structure is generally defined
Body stores these information.Therefore, when obtaining note information sequence, each note information can be searched from the structure.
However, although note height is normally at, section [21,108] is interior, the note of most of note in the song of part
Height is located at an a small range in the section, that is to say, that the difference between most of note in a song is smaller.
For example, the note height of most of note is located in section [55,75] in the song of part.
102, to each note height in the note information sequence, institute is calculated according to preset function and the note height
State the replacement values of note height, wherein when the independent variable of the preset function is located at the height of the note in the note information sequence
When spending in at least partly range of value range, the derived function of the preset function is more than 1.
Since each note height difference in note information sequence is smaller, in the present embodiment, also according to preset function
Calculate the corresponding replacement values of each note height.Wherein, when the independent variable of the preset function is located at the note information sequence
When in at least partly range of the note height value range in row, the derived function of the preset function is more than 1.Specifically,
The maximum note height of value is d in note information sequence, and the note height of value minimum is c, to being located at range [c, d] extremely
Two independents variable x1 and x2 within the scope of small part, the corresponding functional values of wherein x1 (namely a note height) (namely note
The replacement values of height x1) it is y1, the corresponding functional values of x2 (namely a note height) are y2 (namely the replacements of note height x2
Value), since derived function is more than 1, (y1-y2)/(x1-x2) is more than 1 namely y1-y2 and is more than x1-x2, in this way, will be located at model
The variable for enclosing note height substitution preset function in at least partly range of [c, d] falls into a trap enumeration function value as the note height
Replacement values, the difference between the replacement values of the note height is greater than the difference between former note height, pulled open note height
The distance between degree so that the variation of note height is more obvious.
For concrete example, the preset function is f (x)=(q-p) × (2(x-c)/(d-c)- 1)+p, wherein c believes for note
The note height of value minimum in sequence is ceased, d is the maximum note height of value in note information sequence, and [p, q] is described new
The preset interval of note height in note information sequence.
103, to each note height in the note information sequence, note height is replaced with into the note height
Replacement values, form new note information sequence.
Since the difference in note information sequence at least partly between the replacement values of note height is greater than former note height
Between difference each note height in original note information sequence is therefore replaced with into the replacement values of the note height,
Form new note information sequence.For concrete example, note information sequence includes three note informations, respectively (35667,
398,71), (36068,264,69) and (36335,622,71), first numerical value wherein in each note information are note
Time started, second numerical value are the duration, and third numerical value is note height.71 are substituted into preset function and calculates letter
Numerical value is 92, by 69 substitution preset functions fall into a trap enumeration function value be 73, then, replace note height after formed new note letter
It is (35667,398,92), (36068,264,73) and (36335,622,92) to cease sequence.
104, tone line is shown according to the new note information sequence.
In the present embodiment, there are many ways to showing tone line according to new note information sequence.For example, new note information sequence
Each note information in row includes time started, end time (or duration) and note height, in display tone
When line, each note information is a line segment for being parallel to x-axis in xy coordinate planes, wherein the cross of the starting point of the line segment
Coordinate be in the note information at the beginning of, the abscissa of terminal is end time (or line segment in the note information
Length be duration in the note information), the ordinate of the line segment is the note height in the note information.
In another example each note information is numbered, each number is for uniquely indicating the note information.It is showing
When tone line, each note information is a point in xy coordinate planes, wherein the abscissa of the point is the note information
Number, ordinate are the note height in the note information.
It is high by using preset function and note to each note height in the note information sequence in the present embodiment
Degree calculates the replacement values of the note height, since the derived function of the preset function is greater than 1, then the note letter calculated
Gap in breath sequence between the replacement values of each note height is greater than the gap of each note height, in this way, by note information sequence
Each note height in row replaces with the new note information sequence formed after the replacement values of the note height, is believed according to the new note
The fluctuating for the tone line that breath sequence is shown is more obvious compared to the fluctuating of the tone line shown according to former note information sequence, helps

f1' (x), and f2' (x) is more than f3‘(x)。
Wherein, preset function can be a smooth curve, can also be piecewise function, this is not restricted.
Since the value of the note height of each note in song is largely focused on the stage casing part (m, n) of [c, d], it is located at
The value of head and the tail two parts [c, m] and [n, d] are less, are become to each note height in note information sequence using preset function
When changing, since derived function of the independent variable when [c, d] is interior of preset function is more than independent variable leading in [c, m] and [n, d] interior
Function can replace with the value range mistake after the replacement values of the note height to avoid each note height in note information sequence
Greatly, and then avoid the space occupied by final shown tone line excessive.
Further, it is preferred that f1' (x) and f3' (x) is respectively less than 1.Namely in use preset function in note information sequence
