Abstract
The invention discloses a processing method of large audio data, comprising the following steps of: extracting crest data from the large audio data, displaying the crest data on a display, revising the audio data on a graph interface based on edition needs, and correspondingly revising a section information table and the crest data. Matching with spectrogram display, the invention can provide examination in a mode of frequency component. Because of the special section information table and the special crest data, the invention reduces unnecessary operations, enhances the edition speed, and is more humanized by adding steps of revocation and rework.
Description
Technical field
The utility model has related to the drawing method of the disposal route of large audio data, particularly corresponding collection of illustrative plates.
Background technology
At present, the processing to big audio file exists the not high drawback of efficient, function singleness.Patent Office of the People's Republic of China discloses the patent of " a kind of method of carrying out audio editing and conversion through the intercepting audio volume control " on May 31st, 2006; But there is the serious low problem of efficient in it in audio editing; Particularly for the editor of large audio data; Form with whole picture points realizes, can not satisfy the requirement of user to efficient; This patent is the special disposal to cancelling and reforming not, can cause under the not good situation of edited result and will do again, waste efficient; This patent just is directed against the realization of oscillogram, but it is in not demonstration of frequency, can't satisfy some professional persons' needs.
Summary of the invention
The technical matters that the present invention solves is; Introduce interface display theory and segments theory; Proposed to large audio data shearing, duplicate, delete, paste, cancel, reform, preserve a whole set of disposal route; And the broadcast of having arranged in pairs or groups, collection of illustrative plates demonstration and zoom function, have convenient, the fireballing characteristics of editing.
Concrete performing step is following:
1, obtains voice data;
2, extract the crest data, set up the segment information table, show collection of illustrative plates;
3, editing and processing;
4, revise crest data and segment information table, show collection of illustrative plates;
5, play checking;
6, convergent-divergent is checked details;
7, preserve.
Theoretical according to interface display, human eye can be ignored details automatically for mass data, pays attention to profile substantially.For this reason, the present invention has produced the hidden file of its crest data of record when large audio data is handled, and with itself and voice document link, mapping thereafter just produces on crest data basis.During amplification, when the crest data can not replace True Data, read True Data, full point is drawn.
According to segments theory, to the data of an integral body, shear, delete and paste one section and all can revise its hop count.According to its segment mark, set up corresponding index, form a proprietary segment information table, so that obtain corresponding data.
The present invention occurs with the form of oscillogram incessantly, and the demonstration of sound spectrograph also is provided, and to checking of voice spectrum component convenience is being provided.
Description of drawings
Fig. 1 is the process flow diagram that large audio data is handled
Embodiment
Following referring to Fig. 1 embodiment of the present invention:
1, reading in voice data, generally is that the form with file reads in, and can be formatted files such as wav, mp3, wma, becomes the pcm formatted data with decoder decode.The initialization segment information.
2, judgment data length scale less than certain threshold value (the present invention selects 40000 sampling lengths), is little voice; Directly showing the demonstration of drawing; Otherwise be big voice, begin to extract the crest data, just every segment (the present invention gets 100 sampling lengths) data are tried to achieve value.
Draw according to the crest data.
3, voice data is carried out following editing and processing, be primarily aimed at large audio data here.
(1) shear, judge that the initial sum final position of shearing at affiliated hop count, revises the segment information table, confirm final hop count by following four kinds of situation: all shear certain n segment data for first kind, hop count subtracts n; Second kind begins to shear at a certain section, and hop count is constant; The third is sheared a certain section ending place, and hop count is constant; In the middle of a certain section, shear for the 4th kind, hop count adds one.Generate the shear plate data, in order to the usefulness of stickup.
(2) duplicate, do not revise hop count, generate the shear plate data, in order to the usefulness of stickup.
(3) deletion is revised the segment information table with (1), but is not preserved the shear plate data.
(4) paste, judge paste position, revise the segment information table, handle by following three kinds of situation: first kind of pasting data is to a certain section beginning, and hop count adds one; Second kind of pasting data is to a certain section end, and hop count adds one; The third pasting data is to a certain section centre, and hop count adds two.Preserve pasting data, in order to the usefulness of picture and preservation.
(5) cancel, read in crest data and segment information table after cancelling, accomplish destruction operation.
(6) reform, read in crest data and segment information table after reforming, accomplish redo.
Wherein segment information table data definition is following:
Typedef struct//data segment information
{
String fileName; File under the // data
Int nDataStartNow; The relative start address of // current data
Int nDataStartOrig; // raw data start address
Int nDataLen; // data length
}PARTDATAINFO；
4, judging that the data behind the editor are big audio file, is just to draw according to segment information table and crest data, is not directly to draw according to raw data.
5, preserve audio data file, according to the difference of form, to the voice data preservation of encoding.
6, can roller and button convergent-divergent collection of illustrative plates, check detailed information to satisfy.During amplification, when crest literary composition data deficiencies when showing, according to the segment information table, obtain the realAudio data, full point is drawn.
7, through playing, can verify the correctness of its processing.
8, the drafting of sound spectrograph is drawn sound spectrograph according to current data presented, moves size through the change frame and realizes convergent-divergent.
Claims (4)
1. the disposal route of large audio data, it comprises that data shear, duplicate, delete, paste, cancel, reform, preserve a whole set of disposal route, and according to select to play, collection of illustrative plates shows and convergent-divergent,
Concrete performing step is following:
(1) obtains voice data;
(2) initialization segment information, every little segment data are tried to achieve and are worth most to extract the crest data, set up the segment information table, to draw, show collection of illustrative plates according to the crest data;
(3) editing and processing comprises: data are sheared, duplicate, delete, paste, cancel, are reformed;
(4) revise crest data and segment information table, show collection of illustrative plates;
(5) play checking;
(6) convergent-divergent is checked details;
(7) preserve.
2. the disposal route of large audio data according to claim 1 is characterized in that data are extracted crest, generates the crest file, and its source as picture.
3. the disposal route of large audio data according to claim 2 is characterized in that generating the segment information table, and various editing and processing all can be revised segment information table and crest file, draws according to segment information table and crest file.
4. the disposal route of large audio data according to claim 1 is characterized in that the realization of sound spectrograph, under the demonstration of sound spectrograph, realizes audio editing.
