Abstract
The invention relates to a method of quickly verifying accuracy and synchronization of a recorded audio content. The method comprises steps: S01, when a recording devices performs recording while an audio source is played; S02, after recording is carried out for a preset time, the recording time of the recording device and the playing time of the audio source are checked and compared during the recording process; if the two have the consistent moving frequency, the recording time is normal, and testing is continued; and if the two have the inconsistent moving frequencies, the recording time moves slower or quicker, the recording time is abnormal, and the recording content is wrong; and S03, the recorded audio file and the audio source are played synchronously, and contents of the two need to be adjusted to be synchronous and consistent when playing starts; during the playing process, the contents played by the two are monitored and compared synchronously, and if the contents are consistent, synchronization is realized, and the test is good; and if the contents are inconsistent or not synchronous, the test is no good (NG). the method of the invention is simple, recording can be quickly verified, accuracy of the recording time, accuracy of the recording content, synchronization of the recording content can the like can be verified.
Description
Technical field
The present invention relates to audio recording verification technique field, particularly a kind of can fast verification recording substance accuracy, synchronism method.
Background technology
During test sound-recording function, traditional method of testing is studio sound or music, playback file judges the quality of tonequality again, but whether this kind of method can not effectively accurately and fast check out the sound-content of recording correct, whether record length is correct, and whether recorded content exists the problems such as time delay.
Summary of the invention
The present invention relates to a kind of can fast verification recording substance accuracy, synchronism method.
The present invention adopts following scheme to realize: the method is characterized in that and comprise the following steps:
Step S01: while source of sound broadcasting, sound pick-up outfit starts recording;
Step S02: record a schedule time, in Recording Process, checks and the recording time of comparison sound pick-up outfit and the reproduction time of source of sound; If both walk dynamic frequency unanimously, then recording time is normal, continues test; If it is inconsistent that both walk dynamic frequency, recording time is walked about and be there is partially slow or fast phenomenon, then record length is abnormal, and recorded content is made mistakes;
Step S03: the recording file of recording and source of sound are simultaneously play, need be adjusted to synchronous consistent by both contents when starting to play; In playing process, monitor and the content play both contrasting, if content is consistent and synchronous, then test is passed through simultaneously; If content is inconsistent or asynchronous, then test NG.
In an embodiment of the present invention, described source of sound is the equipment possessing audio playing function.
In an embodiment of the present invention, described sound pick-up outfit is recording pen.
In an embodiment of the present invention, the described schedule time is 1 ~ 3 minute.
In an embodiment of the present invention, described step S02 carries out captured in real-time by a video camera to sound pick-up outfit and source of sound reproduction time, and is compared by the numeral of graphical analysis by the image specific region i.e. time showing district of two equipment; If inconsistent, then send alarm.
In an embodiment of the present invention, step S03 is the audio frequency synchronously play by audio collecting device collection, and compares to the audio frequency gathered, if inconsistent, carries out alarm.
In an embodiment of the present invention, described audio collection module comprises the first audio collecting device and the second audio collecting device, described first audio collecting device gathers the audio frequency that sound pick-up outfit is play, and described second audio collecting device gathers the audio frequency that audiogenic device is play; The audio frequency of collection is inputted a PC by the first described audio collecting device and the second audio collecting device to carry out judging that whether two audio contents are consistent.
The inventive method is simple, can verify sound-recording function fast, record length correctness, recording substance accuracy, recording substance synchronism etc.
Accompanying drawing explanation
Fig. 1 is the inventive method schematic flow sheet.
Embodiment
For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here to implement with multiple, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention.Therefore the present invention is not by the restriction of following public embodiment.
The present embodiment provide a kind of can fast verification recording substance accuracy, synchronism method, it is characterized in that comprising the following steps:
Step S01: while source of sound broadcasting, sound pick-up outfit starts recording;
Step S02: record a schedule time, in Recording Process, checks and the recording time of comparison sound pick-up outfit and the reproduction time of source of sound; If both walk dynamic frequency unanimously, then recording time is normal, continues test; If it is inconsistent that both walk dynamic frequency, recording time is walked about and be there is partially slow or fast phenomenon, then record length is abnormal, and recorded content is made mistakes;
Step S03: the recording file of recording and source of sound are simultaneously play, need be adjusted to synchronous consistent by both contents when starting to play; In playing process, monitor and the content play both contrasting, if content is consistent and synchronous, then test is passed through simultaneously; If content is inconsistent or asynchronous, then test NG.
In an embodiment of the present invention, described source of sound can for possessing the equipment of audio playing function, and it comprises mobile phone, music player or panel computer etc.Preferably, sound pick-up outfit of the present invention is recording pen.
In step S02 of the present invention, the described schedule time is 1 ~ 3 minute, and user can be set as 1,2 or 3 minute, to guarantee that thick gravy process time walks the consistance of dynamic frequency.
In an embodiment of the present invention, for realizing intellectuality and the robotization of checking, described step S02 carries out captured in real-time by a video camera to sound pick-up outfit and source of sound reproduction time, and is compared by the numeral of graphical analysis by the image specific region i.e. time showing district of two equipment; If inconsistent, then send alarm, its alarm mode can be local sound and light alarm, and automatically records alert information afterwards in warning, and this information comprises recording time and reproduction time and which period to occur the inconsistent and current date etc. in.In addition, in the present embodiment, step S03 is the audio frequency synchronously play by audio collecting device collection, and compares to the audio frequency gathered, if inconsistent, carries out alarm.Preferably, described audio collection module comprises the first audio collecting device and the second audio collecting device, and described first audio collecting device gathers the audio frequency that sound pick-up outfit is play, and described second audio collecting device gathers the audio frequency that audiogenic device is play; The audio frequency of collection is inputted a PC by the first described audio collecting device and the second audio collecting device to carry out judging that whether two audio contents are consistent.
