Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
It should be noted that, the user information (including but not limited to user equipment information, user personal information, etc.) and the data (including but not limited to data for presentation, analyzed data, etc.) related in the present application are both information and data authorized by the user or sufficiently authorized by each party; correspondingly, the application also provides a corresponding user authorization entry for the user to select authorization or select rejection.
In one embodiment, as shown in fig. 1, a method for controlling a tone is provided, and this embodiment is applied to a terminal for illustration, where the terminal may be, but is not limited to, a personal computer, a notebook computer, a smart phone, a tablet computer, an internet of things device, and a portable wearable device. In this embodiment, the method includes the steps of:
wherein a client of the electronic tone control software may be turned on, through which an audio play event of the system for a target song is detected, e.g. when a system play of song a is detected, song a may be taken as the target song.
In practical application, a preset time range can be obtained, when the playing operation of the system for the target song is detected, the target playing time can be determined according to the current playing time and the preset time range of the target song, and then an audio segment from the current playing time to the target playing time in the target song can be used as a target audio segment, so that the target audio segment is further subjected to basic tone analysis, and the target audio segment can comprise a plurality of audio frames of the target song at a plurality of playing times.
Specifically, the system may have a plurality of playing devices for audio output, and when the system is detected to play the song a, the playing device playing the song a may be used as a target playing channel, for example, a plurality of playing channels connected to the system may be acquired, through available screening processing on the plurality of playing channels, according to the detected audio playing event of the system for the target song, a target playing channel corresponding to the audio playing event is determined, and further, audio stream data output by the target playing channel may be acquired through a client of the electronic tone control software, so as to acquire a target audio clip.
In an example, when it is detected that the user starts playing song a (i.e., the target song), a future segment of a preset time range (e.g., 4 seconds) may be intercepted for the playing song a, for example, a starting playing time of 0 seconds (i.e., the current playing time), and then a song segment of 0 to 4 seconds (i.e., the target time period) may be intercepted as the target audio segment.
In an alternative embodiment, as shown in fig. 2, when the playing operation of the system on the target song is detected, the segment acquisition of the whole song may be planned according to the total song duration of the target song, for example, target audio segments in multiple target time periods, such as a song segment of 0 to 4 seconds, a song segment of 4 to 8 seconds, and the like, may be respectively acquired according to time sequence based on a preset time range (such as 4 seconds).
as an example, the song key corresponding to each playing time in the target period included in the predicted key information may be different keys, for example Bm, db, dbm, gbm, A, B, D, E, abm, am, dm, em, and may also include other keys, which is not specifically limited in this embodiment.
In a specific implementation, audio data corresponding to each playing time in the target audio clip can be obtained, the audio data can include a plurality of audio frames of the target song, and then a song key corresponding to each playing time can be obtained according to a key corresponding to each audio frame in each playing time and used as prediction key information corresponding to the target time period.
For example, for any playing time, the key of each corresponding audio frame can be obtained through key analysis, then the weights corresponding to different keys can be determined according to the number of different keys, the key analysis result of any playing time can be obtained, and then the song key corresponding to any playing time can be determined according to the key analysis result.
For another example, aiming at a plurality of key in the key analysis result at any playing time, the key corresponding to the maximum weight in the key analysis result, such as the key with the largest occurrence number, can be used as the song key corresponding to any playing time, so that the user can obtain the song played by the client and obtain the key analysis result based on the weight calculation, and the predicted song key can be accurately identified.
In an example, since a whole song is a key, the climax part in some songs has a rising and falling operation, and each song adopts a key which is not suitable for a whole song and cannot meet the requirement of generating electric sound effects, compared with the traditional method that the same key is adopted for a song, the key can cause the condition that the key has a voice running at the climax part; according to the technical scheme, the key analysis can be performed on the audio frequency fragment of the future accompaniment for a period of time (such as 4 seconds) in advance, so that the song key of the future period of time (such as 4 seconds) is obtained, the condition that a user runs the key due to the change of the key of the lifting key part in the song can be avoided, the generation of the electric sound effect is more stable, and the error rate of the voice running key is reduced.
After the predicted key information is obtained, the predicted key information can be synchronized to audio host software of the system, and because the audio host software can be loaded with the electric tone plug-in, the electric tone plug-in can be synchronized to the electric tone plug-in of the audio host software, and the electric tone plug-in is controlled to generate electric tone effects matched with a target song based on song keys corresponding to playing moments in a target time period.
In an example, the audio host software may be loaded with a plurality of plugins, such as reverberation, noise reduction, equalizer, and electric plug-in, and the electric plug-in needs to be consistent with the accompanying key to achieve the effect of repairing the sound.
In yet another example, through the client of the electric tone control software, the playing progress of the song played by the user can be obtained, the segments can be cut, the predicted tone information can be obtained by analyzing in advance, the playing progress can be circularly obtained to obtain the predicted tone information corresponding to each segment, and then the electric tone plug-in tone can be modified according to the predicted tone information to generate the electric tone effect matched with the played song.
Compared with the traditional method, the technical scheme of the embodiment ensures that a user does not need to manually operate by automatically processing the whole flow of the electric tone control; by analyzing the key in advance, the generated electric sound effect can be flexibly adjusted aiming at any tone changing part of the song, and the future song segment key obtained based on the advance judgment can be avoided when a user sings the song due to accompanying rising and falling of the tone.
According to the method for controlling the electric tone, when the playing operation of the system for the target song is detected, the target audio fragment of the target song in the target time period is obtained, then the prediction tone information corresponding to the target time period is determined according to the target audio fragment, and then the prediction tone information is synchronized to the audio host software of the system, the electric tone plug-in unit loaded in the audio host software is controlled, the electric tone effect matched with the target song is generated based on the song tone corresponding to each playing time in the target time period, the automatic obtaining and synchronization of the tone information of the non-played audio fragment during song playing are realized, the electric tone is automatically adjusted, the tone can be flexibly adjusted in advance through the prediction of the song tone corresponding to the time period after the current playing time, manual searching and modifying operation are not needed, the control efficiency of the electric tone is improved, the electric tone can be accurately predicted, and the electric tone effect matched with the generation of the tone change of the tone is guaranteed.
In one embodiment, the obtaining the target audio clip of the target song in the target time period may include the following steps:
determining a target playing time according to the current playing time of the target song and the preset time range; and taking the audio frequency fragment from the current playing time to the target playing time in the target song as the target audio frequency fragment.
In practical application, when it is detected that a user starts playing song a (i.e., a target song), a future segment in a preset time range (e.g., 4 seconds) may be intercepted for the playing song a, for example, the playing start time is 0 seconds (i.e., the current playing time), and if the target playing time to be intercepted is 4 seconds, the target audio segment may be obtained by intercepting a song segment of 0 to 4 seconds (i.e., the target time period).
In an alternative embodiment, for a client to collect audio stream data output by a target playback channel, a system API (Application Programming Interface, application program interface) may be used to obtain the target playback channel, and then a portaudio module with a loop-back WASapi may be used to read the audio stream output by the target playback channel as audio stream data.
In this embodiment, the target playing time is determined according to the current playing time and the preset time range of the target song, and then the audio segment from the current playing time to the target playing time in the target song is used as the target audio segment, so that the unreflected audio segment can be automatically obtained when the song is played, and data support is provided for further key analysis and prediction.
In one embodiment, the determining, according to the target audio segment, prediction key information corresponding to the target time period may include the following steps:
acquiring audio data corresponding to each playing time in the target audio fragment; the audio data includes a plurality of audio frames of the target song; and obtaining the song key corresponding to each playing time according to the key corresponding to each audio frame in each playing time, and taking the song key as the prediction key information corresponding to the target time period.
In an example, by acquiring audio data corresponding to each playing time in the target audio segment, for each playing time, a key of each audio frame corresponding to the playing time may be acquired based on key analysis, and then weights corresponding to different keys may be determined according to the number of different keys, so as to obtain a key analysis result of each playing time, so as to determine a song key corresponding to each playing time. The key analysis result can be displayed in a ranking list mode, and calculation can be performed based on the ranking list mode to obtain weights corresponding to different keys, so that the song keys corresponding to each playing time can be further determined. If the ranking list mode can be a column diagram display mode, columns with different colors or different textures can be used for marking according to different basic tones, the height of the columns corresponding to different basic tones can represent the weight of the columns, and other mark display modes can be used, so that the method is not particularly limited in the embodiment.
In an alternative embodiment, by performing a key analysis on the obtained audio stream, a scale corresponding to each audio frame at each playing time in the target audio segment can be obtained, a predicted key and a scale corresponding to each audio frame can be displayed, and a key and a scale corresponding to each playing time can be displayed for each playing time; other analyzed music theory related information can be displayed, and the embodiment is not particularly limited.
In this embodiment, by acquiring audio data corresponding to each playing time in the target audio segment, and further obtaining a song key corresponding to each playing time according to the key corresponding to each audio frame in each playing time, as predicted key information corresponding to the target time period, the key analysis can be performed based on weight calculation, and the predicted song key can be accurately identified.
In one embodiment, the method may further comprise the steps of:
and in the continuous playing process of the target song, after the end of the playing of the target time period corresponding to the latest acquired target audio fragment is detected, acquiring the target audio fragment of the target song in the next target time period as the latest acquired target audio fragment.
In a specific implementation, taking a song to be played by a user as an example, the playing start time is 0 second (i.e., the current playing time), a song segment of 0 to 4 seconds (i.e., the target time period) can be intercepted as a latest acquired target audio segment, and then when the playing progress reaches 4 seconds, i.e., when the playing end of the target time period corresponding to the latest acquired target audio segment is detected, a song segment of 4 to 8 seconds (i.e., the next target time period) can be intercepted for the current playing time for 4 seconds, so as to circularly acquire the playing progress segment and intercept the song segment.
In this embodiment, in the continuous playing process of the target song, after the end of the playing of the target time period corresponding to the target audio segment acquired last time is detected, the target audio segment of the target song in the next target time period is acquired and used as the target audio segment acquired last time, so that the playing progress can be circularly acquired to acquire the prediction key information corresponding to each segment, and the control efficiency of the electric tone key is improved.
In one embodiment, the method may further comprise the steps of:
and in the continuous playing process of the target song, when the generation of corresponding prediction key information aiming at the latest acquired target audio fragment is detected, acquiring the target audio fragment of the target song in the next target time period as the latest acquired target audio fragment.
In practical application, the client can segment and plan the whole song according to the total song duration of playing the song to obtain each song segment under the condition of not occupying excessive performance. Taking the example that the user starts playing a song, the playing time is 0 second (i.e. the current playing time), a song segment of 0 to 4 seconds (i.e. the target time period) may be intercepted as the latest acquired target audio segment, and then, in the case that it is detected that the 0 to 4 seconds audio segment is already analyzed, that is, when it is detected that corresponding prediction key information is generated for the latest acquired target audio segment, a song segment of 4 to 8 seconds (i.e. the next target time period) may be intercepted to acquire the song segment in a segmented manner.
In this embodiment, in the continuous playing process of the target song, when it is detected that the corresponding prediction key information is generated for the target audio segment acquired last time, the target audio segment of the target song in the next target time period is acquired as the target audio segment acquired last time, so that the prediction key information corresponding to each segment can be analyzed based on segment planning, and the electric tone control efficiency is improved.
In one embodiment, the controlling the electrical plug-in loaded in the audio host software to generate an electrical sound effect matched with the target song based on the song key corresponding to each playing time in the target time period may include the following steps:
According to the song basic tone corresponding to each playing time in the target time period, determining tone change information of the target song in a preset time range after the current playing time; and generating the electric sound effect matched with the target song according to the playing progress of the target song by adopting the tone change information.
As an example, the pitch change information may be used to characterize the pitch change of a particular pitch change portion of a song being played, such as the up-down state of the presence of a climax part of the song.
In an example, since the tone plug-in needs to be consistent with the key of accompaniment to achieve the tone trimming effect, by synchronizing the predicted key information to the tone plug-in of the audio host software, the key of the tone plug-in the audio host software can be automatically updated after the client analyzes the song key of the time period within the preset time range after the current playing time. Therefore, the modification of the key scale can be automatically completed for the electric sound plug-in according to the predicted key information, manual searching and modification operation are not needed, the key can be analyzed in advance to be flexibly adjusted, and the generation of the matched electric sound effect for the key change is ensured.
In this embodiment, the tone change information of the target song in the preset time range after the current playing time is determined according to the song key corresponding to each playing time in the target time period, and then the tone change information is adopted to generate the electric sound effect matched with the target song according to the playing progress of the target song, so that the key of the electric sound plug-in unit can be flexibly adjusted adaptively, and the situation of voice running caused by accompanying rising and falling of the tone is avoided.
In one embodiment, the method may further comprise the steps of:
displaying the playing progress of the target song in a first area of a playing display interface; and displaying the song key corresponding to each playing time and the key related information thereof in the target time period corresponding to the target audio fragment in a second area of the playing display interface.
In an example, as shown in fig. 2, the playing progress of the target song may be displayed in a first area of the playing display interface, the key and scale (i.e. the key of the song and its key related information) corresponding to each playing time in the target time period corresponding to the target audio clip may be displayed in a second area of the playing display interface, and other analyzed music theory related data may be displayed, which is not limited in this embodiment.
In this embodiment, by displaying the playing progress of the target song in the first area of the playing display interface and displaying the song key corresponding to each playing time and the key related information thereof in the second area of the playing display interface in the target time period corresponding to the target audio clip, the related prediction information obtained by the key analysis can be visually displayed, and the user can obtain the key of the song at the future time.
In one embodiment, as shown in fig. 3, a flow chart of another method of electric tone control is provided. In this embodiment, the method includes the steps of:
in step 301, when a playing operation of the system for the target song is detected, a target playing time is determined according to the current playing time of the target song and a preset time range. In step 302, the audio clip from the current playing time to the target playing time in the target song is used as the target audio clip. In step 303, audio data corresponding to each playing time in the target audio clip is obtained; the audio data includes a plurality of audio frames of the target song. In step 304, according to the key corresponding to each audio frame in each playing time, a song key corresponding to each playing time is obtained and used as the prediction key information corresponding to the target time period. In step 305, the predicted key information is synchronized to the audio host software of the system, and the electric sound plug-in loaded in the audio host software is controlled to generate electric sound effects matched with the target song based on the song key corresponding to each playing time in the target time period. In step 306, in the continuous playing process of the target song, after it is detected that the playing of the target time period corresponding to the latest acquired target audio segment is finished, the target audio segment of the target song in the next target time period is acquired as the latest acquired target audio segment.
