In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
A first embodiment of the present invention relates to an authoring method applied to an electronic device; the electronic device may be a terminal or a server, and the electronic device in this embodiment and each of the following embodiments is described by taking the server as an example. The following describes the implementation details of the authoring method of this embodiment in detail, and the following is only provided for the convenience of understanding and is not necessary for implementing this embodiment.
Application scenarios for embodiments of the present invention may include, but are not limited to: any room equipped with a family music system, a music classroom, a singing hall, a pub of education institutions such as school kindergartens and the like, a gymnasium equipped with a background music system, a professional recording studio of a record company or an independent musician and the like.
The specific flow of the authoring method of the present embodiment may be as shown in fig. 1, and includes:
specifically, the server can acquire the unconscious behavior of the target object and the corresponding time point in real time in the music playing process. The unconscious behavior is an instinctive behavior which is not judged by subjective analysis. Due to the unique rhythm of the music, the target object can make various unconscious behaviors along with the melody of the music in the music playing scene, and the unconscious behaviors can truly and accurately represent the interaction between the target object and the played music and reflect the feeling of the target object on the music.
In a specific implementation, the server may determine music to be re-created, and send the music to the playback device for playing, where the playback device may be: the system comprises a sound box capable of being connected with the internet, a home radio, a mobile phone, a desktop computer, a notebook computer, a tablet computer, a professional sound playing and recording device and the like. Before playing, the server can also determine the identity of the target object, and in the process of playing music, the camera and/or the microphone can acquire the unconscious behaviors of the target object and the corresponding time point in real time. The camera and/or the microphone may be built-in to the playback device, or may be connected to the outside of the playback device. Wherein the corresponding time point, i.e. the time point corresponding to the unintentional behavior made by the target object, also corresponds to the time axis of the music, since the unintentional behavior of the target object is obtained during the whole music playing process. The target object is an individual without independent awareness, such as: children, cats, dogs, etc.
In one example, the server determines that the music to be re-created is a music nail, the target object is a puppy A, the server records the unconscious behaviors of the puppy A such as barking through a microphone in the playing process of the music nail, shoots the unconscious behaviors of the puppy A such as circling and running through a camera, and records the occurrence time points of the unconscious behaviors.
Such as: the puppy a barks at the 45 th second of music a playing, and the server can acquire the barking sound of the puppy a at the 45 th second of music a playing and record the corresponding time point as 45 seconds, and store the recording in a database inside the server.
In another example, the server determines that the music to be re-created is music B, the target object is child B, and during playing of music B, the server records unconscious behaviors such as shouting of child B through a microphone, shoots unconscious behaviors such as clapping hands and stomps feet of child B through a camera, and records the time points of occurrence of these unconscious behaviors.
Such as: the child B makes a clapping laugh in the 27 th second of the music B, the server can acquire the clapping action and the laugh sound made by the child B in the 27 th second of the music B, and records the corresponding time point as 27 seconds and stores the corresponding time point in a database inside the server.
specifically, after the server obtains the unconscious behavior of the target object and the corresponding time point, the characteristics of the music can be adjusted according to the unconscious behavior and the time point.
In particular implementations, the characteristics of the music include the music's key, timbre, tempo, and sound, volume, and speed, etc.
In one example, the unintentional behavior of the target object includes an unintentional fool behavior, that is, the target object is not interested in the music to be composed, and the server turns down the tune in the music at the time point corresponding to the unintentional fool behavior of the target object according to the acquired time point corresponding to the unintentional fool behavior and the acquired time point corresponding to the unintentional fool behavior of the target object.
In one example, the unconscious behavior of the target object includes the behavior of the sound of the target object, i.e., the behavior of the target object making the sound, and the corresponding time point includes the time point corresponding to the behavior of the sound, and according to the unconscious behavior and the time point, the adjusting of the characteristics of the music can be realized by the sub-steps as shown in fig. 2, which are as follows:
a substep 201 of extracting a first music track corresponding to the music;
in particular, the server may extract a first music track corresponding to music.
In a particular implementation, the track may appear as parallel "tracks" of one strip as seen in the tuning software. Each track defines attributes of the track, such as the timbre, the timbre library, the number of channels, the input/output ports, the volume, etc., of the track.
In one example, the playing device plays music in motion Picture Experts Group Audio Layer III (MP 3) format, and the server can directly use the music in MP3 format as the first Audio track.
In another example, the playing device plays Music short Video (MV) of Music, and the server may determine a Video stream and an audio stream of the MV respectively, and extract the audio stream of the MV from the MV as the first track corresponding to the Music.
A sub-step 202 of creating an empty audio track;
in particular, the server may create an empty track after extracting the first track corresponding to music. Wherein the time axis of the empty track is the same as the time axis of the first track.
In a specific implementation, after the server acquires the first track, a new empty track can be created according to the time axis of the first track, and since the time axis of the new empty track is aligned with the time axis of the first track, the time point corresponding to the action of the target object to make sound also corresponds to the new empty track.
in particular, the server, after establishing the null audio track, may add sound to the null audio track at the target location, acquiring the second audio track. Wherein, the target position is a time point corresponding to the behavior of the sound.
In a specific implementation, after the server creates the empty track, the server may fill the sound emitted by the target object into the target position in the newly created empty track at a time point corresponding to the action of the target object to emit the sound, so as to obtain the second track.
In one example, the music to be re-composed is music B, the target object is child B, child B utters laughter from 2 th to 4 th seconds, cry from 27 th to 31 th seconds, and talking from 125 th to 133 th seconds, the server obtains the time points corresponding to the three sections of sounds and the behavior of uttering the three sections of sounds, fills the laughter uttered by child B into the 2 nd to 4 th seconds of the empty track, fills the crying uttered by child B into the 27 th to 31 th seconds of the empty track, and fills the talking of child B into the 125 th to 133 th seconds of the empty track to obtain the second track.
In another example, the behavior of sound includes a behavior of beat sound, that is, the target object makes sound including the target object makes beat sound, and the time point corresponding to the behavior of sound includes a time point corresponding to the behavior of beat sound. Adding sound to a target position in an empty track, obtaining a second track may be achieved by the sub-steps shown in fig. 3, as follows:
a substep 301, determining the corresponding strength of the behavior of the beat sound;
specifically, after the server acquires the behavior of the beat sound and the time point corresponding to the behavior of the beat sound, the strength corresponding to the behavior of the beat sound, that is, the strength of the beat sent by the target object, can be determined. The behavior of the beat sound includes a behavior of the target object making a sound when tapping the playing device, a behavior of the target object making a hand beat making a sound, a behavior of the target object making a foot stomp making a sound, and the like.
In the specific implementation, a pressure sensor is mounted on the surface of the playing device, a pressure sensor can also be mounted on the ground where the target object stands, the portable pressure sensors can also be attached to both hands of the target object, and the server can acquire the force of slapping the playing device by the target object, the force of slapping the foot of the target object and the like in real time.
In one example, the music to be re-composed is "ringing a bell and jingle", the target object is a child C, the server determines that the child C makes a sound for slapping the playing device in 41 th second, and the server determines that the strength of the beat made by the child C in 41 th second is 5N through a pressure sensor on the playing device.
A substep 302, adjusting the volume of a preset sound effect audio according to the strength of the beat, and obtaining a sound effect audio corresponding to the behavior of the beat sound;
particularly, after the server determines the corresponding force of the beat sound, the volume of the preset sound effect audio frequency can be adjusted according to the corresponding force of the beat sound, and the sound effect audio frequency corresponding to the beat sound is obtained. The preset sound effect audio may be set by a person skilled in the art according to actual needs, and the embodiment of the present invention is not particularly limited thereto. The storage form of the sound effect audio can be a beat audio file.
In one example, the preset audio effect audio is a conga audio effect audio, the strength of the beat sent by the child C in the 12 th second is 5N, the strength of the beat sent by the 13 th second is 7N, the strength of the beat sent by the 14 th second is 6N, the strength of the beat sent by the 15 th second is 5N, the strength of the beat sent by the 16 th second is 4N, the volume of the music is 60dB, and the server determines that the volume of the audio effect audio corresponding to the behavior of the beat sound sent by the 12 th second is: 60+5 equals 65dB, and the sound volume of the effect audio corresponding to the behavior of the beat sound emitted in the 13 th second is: 60+7 is 67dB, and the sound volume of the effect audio corresponding to the behavior of the beat sound emitted in the 14 th second is: the behavior of the beat sound emitted at the 15 th second corresponds to the volume of the effect audio, which is 66dB for 60+ 6: 60+5 is 65dB, and the sound volume of the effect audio corresponding to the behavior of the beat sound emitted in the 16 th second is: 60+4 is 64 dB.
In one example, the server sets a volume adjustment upper limit value of the sound effect audio, and the sound effect audio corresponding to the emitted beat sound is less than or equal to the volume adjustment upper limit value of the sound effect audio. The hearing can be protected by setting the volume adjustment upper limit value of the sound effect audio.
Such as: the upper limit value of the volume adjustment of the sound effect audio is 10dB, the strength of the beat sent by the child C in the 165 th second is 12N, and the server determines that the volume of the sound effect audio corresponding to the beat sound sent in the 165 th second is: 60+10 to 70 dB.
A substep 303, adding a sound effect audio corresponding to the behavior of the beat sound to a target position in an empty audio track, and acquiring a second audio track;
specifically, after obtaining the audio effect audio corresponding to the behavior of the beat sound, the server may add the audio effect audio corresponding to the behavior of the beat sound to the target position in the empty audio track to obtain the second audio track. Wherein, the target position is a time point corresponding to the behavior of the beat sound. The sound effect audio corresponding to the behavior of the beat sound is used, so that the sound effect quality of the acquired second audio track can be higher, and the acquired creative work can show the real emotion of the target object better.
A substep 204 of adjusting characteristics of the music based on the first audio track and the second audio track;
specifically, after the server acquires the second audio track according to the behavior of the target object to make a sound and the time point corresponding to the behavior of the target object to make a sound, the server may adjust the characteristics of the music according to the first audio track and the second audio track.
In a specific implementation, after the server acquires the first audio track and the second audio track, the server may synthesize the two audio tracks according to the time axis of the first audio track and the time axis of the second audio track to adjust the characteristics of the music, and acquire a new audio file, that is, the adjusted music.
And 103, acquiring the creative work according to the adjusted music.
Specifically, the server may obtain the creative work according to the adjusted music after adjusting the characteristics of the music according to the unintentional behavior and the corresponding time point.
In specific implementation, after the server obtains the adjusted music, the server may perform operations such as noise filtering, reverberation adding, and tone quality improvement on the adjusted music to obtain a complete audio file, output the created works, and store the created works in a database inside the server or upload the created works to a preset cloud database.
In one example, after the server obtains the creative work, the creative work can be played immediately for subsequent repair, improvement, and the like.
According to the first embodiment of the invention, in the music playing process, the unconscious behaviors of the target object and the corresponding time point are obtained, and due to the unique rhythmicity of the music, the target object can make various unconscious behaviors along with the melody of the music in the music playing scene, and the unconscious behaviors can truly and accurately represent the interaction between the target object and the played music and reflect the feeling of the target object on the music. According to the unconscious behaviors and the time points, the characteristics of the music are adjusted, the unconscious behaviors made by the target object can participate in the re-creation of the music according to the corresponding time points, and the participation degree of the target object in the re-creation of the music is effectively improved. According to the adjusted music, the creative work is obtained, and considering that most related music re-creation processes are re-created by creators on the basis of original music according to self ideas, the whole re-creation process has strong subjectivity and purposiveness, and the real feeling of the creators on the music cannot be well and really reflected.
A second embodiment of the present invention relates to an authoring method, and the implementation details of the authoring method of the present embodiment are specifically described below, and the following are provided only for easy understanding of the implementation details and are not necessary for implementing the present solution, and fig. 4 is a schematic diagram of the authoring method of the second embodiment of the present invention, and includes:
specifically, the server may record a video of the target object during the music playing.
In specific implementation, the server may call a camera and a microphone built in the playback device, or call a camera and a microphone connected to the playback device externally, and record and shoot the target object in the whole course of the music playback process to obtain a video corresponding to the target object.
specifically, after the server acquires the video, the server may acquire an unconscious behavior of the target object and a corresponding time point according to the video.
in one example, the characteristic of the music includes a volume of the music, the unintentional behavior of the target object includes an action made by the target object, and the corresponding point in time includes a point in time corresponding to the action. Adjusting the characteristics of the music according to the unconscious behaviour and the corresponding points in time can be implemented by the sub-steps as shown in fig. 5, as follows:
4031, determining an emotion score corresponding to the action;
in particular, the server may determine an emotion score corresponding to the action.
In specific implementation, a plurality of standard actions and preset emotion scores corresponding to the standard actions are preset in the server, and the server can compare the actions made by the target object with the preset standard actions and determine the emotion scores corresponding to the actions made by the target object. The preset standard actions and the preset emotion scores corresponding to the standard actions may be set by those skilled in the art according to actual needs, and embodiments of the present invention are not specifically limited thereto. It is understood that the target object's motion includes facial expression motion, limb motion, and the like.
In one example, the server may input the acquired video into a pre-trained motion judgment model, and determine a motion made by a target object in the video in the music playing process and a time point corresponding to the motion. The preset standard actions comprise laughing, smiling, calmness, anger, fear, sadness, crying, clapping hands, stomping feet, ear covering, rolling and the like, wherein the corresponding emotion score of the laughing is 3 points; the emotion score corresponding to smile is 2; the cry corresponding emotion score is 1 point; the emotion score corresponding to anger is 0; the emotion score corresponding to fear is-1; the emotional score corresponding to sadness is-2; the emotion score corresponding to the large crying is-3; the corresponding emotion score of the clapping hands is 2 points; the emotional score corresponding to stomping is 2 points; the emotion score corresponding to ear covering is-2; the score of the emotion corresponding to the roll is-3, etc.
specifically, after determining the emotion score corresponding to the motion according to the motion made by the target object, the server may adjust the volume of the music according to the emotion score corresponding to the motion and the time point corresponding to the motion.
In one example, the music to be re-composed is music B, the volume is 60dB, the target object is child B, the server determines that child B performs an action of covering ears in the 41 th second, the emotion score is-2, and the server may adjust the volume of music B from the 40 th second to the 42 th second to 58 dB; child B was sized and clapped at 133 seconds with an emotion score of 3+ 2-5, and the server could adjust the volume of music B from 132 seconds to 134 seconds to 60+ 5-65 dB. The server may also perform a fade-in fade-out process on the volume adjustment, i.e., slowly increasing or decreasing the volume of the music.
In one example, the server may further set a volume upper limit value and a volume lower limit value, where the volume of the creative work is less than or equal to the preset volume upper limit value and greater than or equal to the preset volume upper limit value. Can guarantee that the volume of creative works can not be too big promptly, protect viewer's hearing, can also guarantee that the volume of creative works can not be too little, guarantee the audio effect.
And step 404, acquiring the creative work according to the video and the adjusted music.
Specifically, the server may obtain the creative work from the video and the adjusted music after obtaining the adjusted music. The video of the target object is combined on the basis of the adjusted music, so that the obtained creative work is more vivid, the content is richer, and the quality of the creative work is further improved.
In a specific implementation, the server may determine an audio stream and a video stream of a video, strip the video stream of the video, use the adjusted music as a new audio stream, and synthesize a new complete video file with the stripped video stream as a creative work.
In one example, obtaining the creative work according to the video and the adjusted music may be implemented by the sub-steps shown in fig. 6, which are as follows:
specifically, the server may determine the emotion score corresponding to each time point of the music from the emotion score corresponding to the action and the time point corresponding to the action.
In a specific implementation, the target object may make multiple actions at the same time point, and the server may determine the emotion scores corresponding to the time points of the music according to the emotion scores corresponding to the actions and the time points corresponding to the actions, that is, calculate the total sum of the emotion scores at the time points of the music.
In one example, the music to be re-composed is music B, and the target object is child B. Child B covered his ears, rolled and cried on the 99 th second, the server determined that child B had an emotion score of-2-3-8 on the 99 th second of music B, child B had laughted, clapped and stomped on the 183 th second, and the server determined that child B had an emotion score of 3+2+ 2-7 on the 183 th second of music B.
specifically, after determining the emotion scores corresponding to the time points of the music, the server may intercept the highlight video from the video according to the time point at which the emotion score exceeds the emotion score threshold and a preset emotion fluctuation duration. The preset emotion score threshold and the preset emotion time period may be set by those skilled in the art according to actual needs, and embodiments of the present invention are not particularly limited thereto.
