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:
step 101, when an audio playing event of a system aiming at a target song is detected, audio stream data output by a target playing channel corresponding to the audio playing event at the current time is obtained; the audio stream data includes a plurality of audio frames of the target song;
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.
As an example, a system may have multiple playback devices (i.e., playback channels) for audio output, and when the system is detected to play song a, the playback device playing song a may be targeted to the playback channel.
In practical application, a plurality of playing channels connected by the system can be obtained, through the available screening processing of the plurality of playing channels, according to the detected audio playing event of the system for the target song, the target playing channel corresponding to the audio playing event is determined, so as to read the audio stream data output by the target playing channel in real time, further the audio stream data output by the target playing channel at the current moment can be obtained, and the audio stream data can comprise a plurality of audio frames of the target song, so that the audio frames are further subjected to the basic tone analysis.
Specifically, the client of the electric tone control software may collect the audio stream (i.e., output audio stream data) in the playing device (i.e., the target playing channel corresponding to the audio playing event), so as to perform real-time tone analysis on the obtained audio stream.
In an alternative embodiment, the system API (Application Programming Interface, application program interface) may be used to obtain the playback device (i.e., the target playback channel), and then the portaudio module with loop-back WASapi may be used to read the audio stream output by the playback device as audio stream data.
Step 102, displaying the key analysis result at the current time; the key analysis result is obtained based on the key corresponding to each audio frame, and the key analysis result is used for representing the weight corresponding to each of different keys obtained by analyzing the target song;
in a specific implementation, since the obtained audio stream data may include a plurality of audio frames of the target song, a key corresponding to each audio frame at the current time may be determined by analyzing a real-time key of the plurality of audio frames, and then weights corresponding to different keys may be determined according to the number of different keys, so as to generate a key analysis result at the current time and display the key analysis result.
In an example, as shown in fig. 2, the key analysis result may be displayed in a ranking list manner, and calculation may be performed based on the ranking list manner, so as to obtain weights corresponding to different keys analyzed for the currently playing song (i.e., the target song), so as to further determine the song key of the currently playing song. The ranking list mode may be a column diagram display mode, and may be identified by adopting columns with different colors or different textures for different key, for example, the height of each column corresponding to different key Bm, db, dbm, gbm, A, B, D, E, abm, am, dm, em in fig. 2 may represent the weight of the column, and other identification display modes may be adopted, which is not limited in this embodiment.
For example, the data of each audio frame at the current time may be obtained by analyzing the data of each audio frame, and then, according to the key corresponding to each audio frame, the key analysis result at the current time may be displayed in a ranking list manner.
In an optional embodiment, through analyzing the real-time key of the obtained audio stream, the corresponding musical scale of each audio frame at the current time can be obtained, and further the corresponding key and the corresponding musical scale of each audio frame at the current time can be displayed, and the corresponding key and the corresponding musical scale at the current time can also be displayed for the whole of the current time; other analyzed music theory related information can be displayed, and the embodiment is not particularly limited.
In yet another example, during the playing process of the target song, the client may continuously collect the audio stream data of the target song, and further, the ranking list data presented in the key analysis result may also continuously change incrementally, so that the more the audio stream data of the target song is collected for a longer time, the more accurate the song key of the currently playing target song is calculated based on the ranking list mode.
Step 103, determining target key information corresponding to the target song according to a plurality of keys in the key analysis result at the current time;
in practical application, aiming at a plurality of key in the key analysis result at the current time, the key corresponding to the maximum weight in the key analysis result can be used as the target key at the current time, and target key information corresponding to the target song, such as the song key of the currently played song, can be obtained according to the target key, so that the song played by the user can be directly obtained by the client, the key result of the song can be obtained based on weight calculation through real-time analysis, and the key of the song can be accurately identified.
For example, after a plurality of audio frames of a target song at the current moment are acquired, the key corresponding to each audio frame can be obtained and stored by analyzing each audio frame, and then the target key information corresponding to the target song can be obtained by calculating the key with the largest occurrence number at the latest moment in the playing process of the target song.
In an alternative embodiment, when it is detected that the key analysis result within a period of time (for example, 5 seconds) varies greatly, the 5 seconds segment may be determined to be a music climax segment of the target song, and then the key analysis result within 5 seconds may be used as the latest data, so as to implement the elastic output of the key analysis result.
Step 104, synchronizing the target key information to audio host software of the system; the audio host software is loaded with a phone plug-in for generating a phone effect matching the target song based on the target key information.
After the target key information is obtained, the target key information can be synchronized to the audio host software of the system, and because the audio host software can be loaded with the electric tone plug-in, the target key information can be synchronized to the electric tone plug-in of the audio host software.
In an example, the audio host software may be loaded with a plurality of plugins, such as reverberation, noise reduction, equalizer, electric plug-in, etc., and the electric plug-in needs to be consistent with the key of the accompaniment to achieve the effect of repairing the voice.
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 collecting the audio stream in real time, each audio frame can be analyzed in real time to obtain corresponding key analysis data, so that the client can elastically output a key analysis result according to the key analysis data of a plurality of audio frames, and analyze the key more accurately, so that the key analysis data can be dynamically and elastically changed, such as one key at the beginning of a song, and the climax fragment of the song is another key, and the actual change condition of the key of the song can be accurately presented.
According to the method for controlling the electric tone key, when the audio playing event of the system aiming at the target song is detected, the audio stream data output by the target playing channel corresponding to the audio playing event at the current moment is obtained, the key analysis result at the current moment is displayed, then the target key information corresponding to the target song is determined according to a plurality of keys in the key analysis result at the current moment, the target key information is synchronized to the audio host software of the system, the key information of the played song is automatically obtained and synchronized, the electric tone key is automatically adjusted, the key analysis is carried out on the audio stream data collected in real time, the corresponding key analysis result is displayed, manual searching and modifying operations are not needed, the control efficiency of the electric tone key is improved, the key of the song can be accurately obtained, and the generation of the matched electric tone effect is ensured.

In an example, a plurality of playing devices (i.e., playing channels) connected by the system may be acquired, for example, by using a system API, and then whether each playing device is valid or not may be checked, for example, useless devices may be screened in a plurality of playing device modes, a target playing device (i.e., a target playing channel corresponding to an audio playing event) may be determined, and then a portaudio module (i.e., a preset audio port module) that loops back to WASapi may be used to intercept an audio stream, so as to read audio stream data output by the target playing device.
For example, as shown in fig. 3, the target playback device may be determined in a plurality of playback device modes, and used as a target playback channel corresponding to the audio playback event.
In this embodiment, by acquiring a plurality of playing channels connected by the system, and through available screening processing on the plurality of playing channels, a target playing channel corresponding to an audio playing event is determined, and then audio stream data output by the target playing channel is read in real time by adopting an audio port module preset in the system, so that audio stream data of songs played by a user are directly acquired by a client, and data support is provided for further key analysis.

In an example, as shown in fig. 4, the key analysis results may be presented in a first area of a key presentation interface. In the playing process of the target song, the client can continuously acquire the audio stream data of the target song, and further the ranking list data presented in the basic tone analysis result can also continuously change in an increasing mode, so that the longer the audio stream data acquisition time of the target song is, the more accurate the song basic tone of the currently played target song is calculated based on the ranking list mode.
In this embodiment, by determining the key corresponding to each audio frame at the current time, further determining the weights corresponding to different keys according to the number of different keys, generating the key analysis result at the current time, and displaying the key analysis result in the first area of the key display interface, the key analysis can be performed on the audio stream data acquired in real time, and the corresponding key analysis result is visually displayed, so that the user can acquire the song key.
In one embodiment, after the step of determining the key corresponding to each audio frame at the current time, the method may further include the steps of:
