Step S100, a first feature input amplitude of a first target audio is acquired.
In this embodiment of the present invention, the first target audio may be an accompanying sound of a real song in an actual K song process, and the accompanying sound of the real song is usually stereo, that is, multichannel sound, and the data format may be a pulse code modulation (Pulse Code Modulation, PCM) format, so in actual implementation, the accompanying sound of the real song may be integrally used as the first target audio, or the accompanying sound of the real song may be subjected to channel separation to obtain a plurality of first mono sounds, and thereafter, the plurality of first mono sounds are respectively used as the first target audio.
In this embodiment of the present application, the sound accompanying a real song may be an 8-bit binaural audio file, or may be a 16-bit binaural audio file, where the storage manner may be a Big-end (Big-Endian) mode, that is, the high-order bytes are arranged at the low address end of the memory, and the low-order bytes are arranged at the high address end of the memory, and meanwhile, the left-channel audio data and the right-channel audio data are stored in an interleaved manner, or may be a small-end mode (Little-Endian), that is, the low-order bytes are arranged at the low address end of the memory, and the high-order bytes are arranged at the high address end of the memory, and meanwhile, the left-channel audio data and the right-channel audio data are stored in an interleaved manner. Referring to fig. 3, taking the real song audio as an 8-bit binaural audio file, the storage mode is a Big-end (Big-Endian) mode, and the left and right channels of the audio can be separated by interleaving and reading to obtain a first left channel audio and a first right channel audio.
In addition, in order to keep the audio to be output in a stable volume range to ensure the hearing comfort of the user, for step S100, in this embodiment of the present application, as an optional implementation manner, it may include step S110, step S120, and step S130 or step S140.
Step S110, determining current input data of the first target audio, and acquiring a first input amplitude of the current input data.
Step S120, determining whether the first input amplitude is greater than the maximum input amplitude of the first target audio in the history input period.
In step S130, if the first input amplitude is greater than the maximum input amplitude of the first target audio in the historical input period, the first input amplitude is used as the first characteristic input amplitude.
In step S140, if the first input amplitude is less than or equal to the maximum input amplitude of the first target audio in the historical input period, the maximum input amplitude is used as the first characteristic input amplitude.
In the embodiment of the application, in the playing process of the first target audio, the audio data read from the audio file at the current moment can be used as the current input data, the first input amplitude of the current input data is obtained, and then whether the first input amplitude is larger than the maximum input amplitude of the first target audio in the historical input period is judged. It may be understood that, in the embodiment of the present application, the history input data with the largest input amplitude in the plurality of pieces of history input data with the reading time before the current time may be used as the largest history input data, and the input amplitude of the largest history input data is the largest input amplitude of the first target audio in the history input period. In addition, it should be noted that, if the current input data is the first input data in the first target audio playing process, the first input amplitude of the current input data may be directly obtained and used as the first characteristic input amplitude.
Taking the whole sound of the real song as a first target audio, taking the 8-bit double-channel audio file shown in fig. 3 as an example, if the current moment is t4 moment, acquiring a first target audio 4 read at t4 moment as current input data, acquiring the sum of input amplitudes of 0 sound channel (left) and 1 sound channel (right) in the first target audio 4 as first input amplitude, judging whether the first input amplitude is larger than the maximum input amplitude of the first target audio in a historical input period (t 1 moment, t2 moment and t3 moment), and assuming that the maximum input amplitude of the first target audio in the historical period is the input amplitude corresponding to t2 moment, namely, the sum of input amplitudes of 0 sound channel (left) and 1 sound channel (right) in the first target audio 2 is the first characteristic input amplitude if the first input amplitude is larger than the input amplitude corresponding to t2 moment, and taking the first input amplitude corresponding to t2 moment as the first characteristic input amplitude if the first input amplitude is smaller than or equal to the input amplitude corresponding to t2 moment.
Then taking the sound of the real song as an 8-bit double-channel audio file shown in fig. 3, carrying out left-right channel separation on the sound of the real song to obtain a first left channel sound shown in fig. 3 and a first right channel sound shown in fig. 3, taking the first left channel sound and the first right channel sound as first target audio as examples, taking the first target audio 41 read at the time of t41 as current input data if the current time is t41, taking the input amplitude of 0 channel (left) in the first target audio 41 as first input amplitude, judging whether the first input amplitude is larger than the maximum input amplitude of the first target audio in a historical input period (t 11 time, t21 time and t31 time), and taking the first target audio 21 as input amplitude of 0 channel (left) in the first target audio, taking the first target audio 21 as first input amplitude if the first input amplitude is larger than the time of t21, taking the first target audio 41 as the first input amplitude, taking the first input amplitude as the first input amplitude, and taking the first target audio 42 if the first input amplitude is larger than the first target audio 1 at the first time of t21 or the first target audio 42 in the historical input period (t 21 time and the first audio 42) as the first input amplitude which is larger than the first target audio 42 in the historical input period (t 21 time and the first audio 2) or the first target audio 2) respectively, assuming that the maximum input amplitude of the first target audio in the history period is the input amplitude corresponding to the time t22, that is, the input amplitude of 1 channel (right) in the first target audio 22, if the first input amplitude is greater than the input amplitude corresponding to the time t22, the first input amplitude is taken as the first characteristic input amplitude, and if the first input amplitude is less than or equal to the input amplitude corresponding to the time t22, the input amplitude corresponding to the time t22 is taken as the first characteristic input amplitude.
Through the arrangement, the first characteristic input amplitude is the input amplitude with the largest selected value from the input amplitudes corresponding to all the input data of the first target audio, so that the obtained audio amplification factor is not too large according to the target output amplitude and the first characteristic input amplitude, and the finally obtained output amplitude is always smaller than or equal to the target output amplitude after the output amplitude of the audio data to be output is regulated in the first target audio according to the audio amplification factor, namely, the audio to be output can be kept in a stable volume range, so that the hearing comfort of a user is ensured.
Step S200, obtaining an audio amplification coefficient according to the target output amplitude and the first characteristic input amplitude.
In this embodiment of the present application, the target output amplitude may be a preset fixed output amplitude, or may be an output amplitude that is set individually according to the hearing habit of the user. Taking the target output amplitude as an example according to the hearing habit of the user, the audio adjusting method provided in the embodiment of the application may further include step S010, step S020 and step S030 before executing step S200.
Step S010, judging whether the target output amplitude exists in the parameter storage library.
In this embodiment of the present invention, since the target output amplitude is an output amplitude that is set individually according to the hearing habit of the user, for a certain user, when the user uses the parameter storage library for the first time, the target output amplitude does not exist, or in other words, there is no candidate output amplitude corresponding to the user. For example, the current user is user a, but the parameter store may only have the amplitude to be output corresponding to user B. Based on this, for step S010, in the present embodiment, as an alternative implementation manner, it may include step S011, step S012, and step S013 or step S014.
Step S011, obtaining audio characteristic information of the second target audio in the output process of the first target audio, where the second target audio is input through the microphone.
Step S012, judging whether the candidate output amplitude corresponding to the audio characteristic information exists in the parameter storage library.
In step S013, if the parameter repository has the output amplitude to be selected corresponding to the audio feature information, it is determined that the parameter repository has the target output amplitude, and the output amplitude to be selected is used as the target output amplitude.
In step S014, if the candidate output amplitude corresponding to the audio feature information does not exist in the parameter repository, it is determined that the target output amplitude does not exist in the parameter repository.
In this embodiment of the present application, the second target audio may be audio information input by the user through the microphone during the output process of the first target audio, for example, lyrics of a real song, and the audio feature information of the second target audio may be a tone attribute of the second target audio. After the audio characteristic information of the second target audio is obtained in the output process of the first target audio, whether the to-be-selected output amplitude corresponding to the audio characteristic information exists in the parameter storage library can be judged, if so, the target output amplitude exists in the parameter storage library, the to-be-selected output amplitude is taken as the target output amplitude, and if not, the target output amplitude does not exist in the parameter storage library.
Through the above arrangement, it can be understood that in the embodiment of the present application, the parameter repository may store the output amplitudes to be selected corresponding to the plurality of audio feature information, so that the method is applicable to a plurality of different users, and in addition, the corresponding relationship between the output amplitudes to be selected and the audio feature information is directly created, so that the execution efficiency of the audio adjustment method can be further improved.
Step S020, if the target output amplitude exists in the parameter storage library, executing the step of obtaining the audio amplification coefficient according to the target output amplitude and the first characteristic input amplitude.
In step S030, if the target output amplitude does not exist in the parameter repository, the target output amplitude is generated in response to the output amplitude setting operation.
For the response output amplitude setting operation included in step S030, the target output amplitude is generated, which may include step S031, step S032, and step S033 as an alternative implementation manner.
In step S031, the second characteristic input amplitude of the first reference audio is obtained, where the first reference audio is the accompanying sound of the target reference song.
In this embodiment of the present application, if the target output amplitude does not exist in the parameter repository, a user setting page may be displayed, where the user setting page is used to display a plurality of reference songs, and the plurality of reference songs may be a preset number of hot songs with top jukeboxes within a preset time period, where the preset time period may be, but is not limited to, one year, half a year, and two months, and the preset number may be, but is not limited to, 10, 20, and 30, and after the user setting page displays the plurality of reference songs, the user may select a target reference song from the plurality of reference songs to play, where the target reference song includes a first reference audio, and it may be understood that in this embodiment of the present application, the first reference audio is an accompanying sound of the target reference song.

In step S0312, the second input amplitude with the largest value among the plurality of second input amplitudes is used as the second characteristic input amplitude.
In step S100 of the present embodiment, if the whole sound of the real song is taken as the first target audio, in step S031 (step S0311 and step S0312) of the present embodiment, the whole sound of the target reference song may be taken as the first reference audio, in step S100 of the present embodiment, if the sound of the real song is separated to obtain a plurality of first mono sounds, and then, the plurality of first mono sounds are taken as the first target audio, in step S031 (step S0311 and step S0312) of the present embodiment, the sound of the target reference song may be separated to obtain a plurality of second mono sounds, and then, the plurality of second mono sounds are taken as the first reference audio.
Similarly, the accompanying sound of the target reference song can be an 8-bit double-channel audio file or a 16-bit double-channel audio file, and the storage mode can be a Big-end mode or a small-end mode (Little-end). Referring to fig. 4, taking an 8-bit binaural audio file as an example, where the audio of the target reference song is stored in a Big-end (Big-Endian) mode, if the entire audio of the target reference song is used as the first reference audio, the second input amplitude of each piece of audio data is obtained in the pieces of audio data of the first reference audio, so as to obtain a plurality of second input amplitudes, in this process, a 0 channel (left) and a 1 channel (right) belonging to the same byte can be used as the first audio data, and the sum of the input amplitudes of the 0 channel (left) and the 1 channel (right) in the audio data is obtained as the second input amplitude of the audio data, then, in a plurality of second input amplitudes, the second input amplitude with the largest value is used as the second characteristic input amplitude, if the audio of the target reference song can be subjected to channel separation to obtain a plurality of second mono sounds, then, respectively, in this process, the audio data can be used as the first reference audio, the left channel and the second audio amplitude of the target reference song can be subjected to interleaving read, and the second audio amplitude is also obtained as the second input amplitude, and the second audio amplitude is obtained in a plurality of the second audio tracks, and the second audio amplitude is obtained in the largest value (left-right) and the second audio amplitude is obtained as the second input amplitude of the second audio data, the input amplitude of each 1 sound channel (right) is used for obtaining a plurality of second input amplitudes, and the second input amplitude with the largest value in the plurality of second input amplitudes is used as the second characteristic input amplitude corresponding to the second right sound channel accompanying sound.
Furthermore, it should be noted that, in the embodiment S100 of the present application, the audio of the real song is subjected to channel separation to obtain a plurality of first monaural tones, and then the plurality of first monaural tones are respectively used as the first target audio, that is, the first left channel audio and the first right channel audio are respectively used as the first target audio, and meanwhile, in step S031 (step S0311 and step S0312) of the present application, the audio of the target reference song is subjected to channel separation to obtain a plurality of second monaural tones, and then the plurality of second monaural tones are respectively used as the first reference audio, that is, when the second left channel audio and the second right channel audio are respectively used as the first reference audio, the second left channel audio is used as the first reference audio corresponding to the first left channel audio, and the second right channel audio is used as the first reference audio corresponding to the first right channel audio.
Step S032, in response to the output amplitude setting operation, the reference amplification factor is acquired.
Step S033, obtaining a target output amplitude according to the second characteristic input amplitude and the reference amplification factor.
In the embodiment of the application, the user may trigger the output amplitude setting operation in the output process of the first reference audio, so that the electronic device may obtain the reference amplification factor in response to the output amplitude setting operation, and then obtain the target output amplitude according to the second characteristic input amplitude and the reference amplification factor. In this embodiment of the present application, the logic relationship between the second characteristic input amplitude, the reference amplification factor, and the target output amplitude may be expressed as:
S_out1＝S_input1*S_Volume1
Wherein s_out1 is the target output amplitude, s_input1 is the second characteristic input amplitude, s_volme 1 is the reference amplification factor.
It can be understood that, because the reference amplification factor is the value obtained by triggering the output amplitude setting operation in the output process of the first reference audio frequency by the user, so that the electronic device responds to the output amplitude setting operation, the obtained target output amplitude is always matched with the hearing habit of the user according to the second characteristic input amplitude and the reference amplification factor, and the volume of outputting the first reference audio frequency with the target output amplitude is also understood to be within the acceptable range of the user, so that the personalized requirement of the user can be met, and the hearing comfort of the user is further ensured.
In this embodiment of the present application, after the target output amplitude is obtained, step S200 may be executed to obtain the audio amplification factor according to the target output amplitude and the first feature input amplitude.
In this embodiment of the present application, the logic relationship between the target output amplitude, the first feature input amplitude, and the audio amplification factor may be expressed as:
S_Volume2＝S_out1/S_input_2
wherein s_volme 2 is the audio amplification factor, s_out1 is the target output amplitude, and s_input_2 is the first characteristic input amplitude.
Step S300, according to the audio amplification factor, the output amplitude of the audio data to be output in the first target audio is adjusted.
In this embodiment of the present application, after the reference amplification factor is obtained, the output amplitude of the audio data to be output in the first target audio may be adjusted according to the audio amplification factor, and finally, the logic relationship between the output amplitude of the audio data to be output, the input amplitude of the audio data to be output and the audio amplification factor may be expressed as:
S_out3＝S_input3*S_Volume2
wherein s_out3 is the output amplitude of the audio data to be output, s_input3 is the input amplitude of the audio data to be output, and s_volme 2 is the audio amplification factor.
It can be understood that, based on the first characteristic input amplitude obtaining manner described in step S110, step S120, and step S130 or step S140, the input amplitude of the audio data to be output must be smaller than or equal to the first characteristic input amplitude, and therefore, the output amplitude of the audio data to be output must also be smaller than or equal to the target output amplitude, that is, the audio to be output can be kept within the stable volume range, and therefore, through the audio adjusting method provided by the embodiment of the present application, the hearing comfort of the user can be ensured.
Further, to enhance the controllability of the audio adjustment method, the audio adjustment method provided in the embodiment of the present application may further include step S040, step S050, and step S060 before performing step S300.
In step S040, in the process of obtaining the output of the first reference audio, the third characteristic input amplitude of the second reference audio is obtained, and the second reference audio is input through the microphone.
In this embodiment of the present application, the second reference audio may be audio information input by the user through the microphone in the output process of the first reference audio, for example, lyrics of the target reference song, and the obtaining manner of the third feature input amplitude may be: and acquiring a third input amplitude of each piece of audio data in the plurality of pieces of audio data of the second reference audio to acquire a plurality of third input amplitudes, and taking the third input amplitude with the largest numerical value in the plurality of third input amplitudes as a third characteristic input amplitude. The foregoing process may be implemented based on the inventive concept provided when the second characteristic input amplitude of the first reference audio is obtained in step S031, which is not described herein.
In step S050, in the process of obtaining the output of the first target audio, the fourth characteristic input amplitude of the second target audio is input, and the second target audio is input through the microphone.
In this embodiment of the present application, the second target audio may be audio information input by the user through the microphone in the output process of the first target audio, for example, lyrics of a real song, and the fourth feature input amplitude may be obtained by: determining current input data of the second target audio, acquiring fourth input amplitude of the current input data, judging whether the fourth input amplitude is larger than the maximum input amplitude of the second target audio in the historical input period, if so, taking the second input amplitude as fourth characteristic input amplitude, and if so, taking the maximum input amplitude as fourth characteristic input amplitude. The foregoing process may be implemented based on the inventive concept provided when the first feature input amplitude of the first target audio is obtained in step S100, which is not described herein.
And step S060, adjusting the audio amplification coefficient according to the third characteristic input amplitude and the fourth characteristic input amplitude.
In this embodiment of the present application, after the third feature input amplitude and the fourth feature input amplitude are obtained, an amplitude ratio of the third feature input amplitude to the fourth feature input amplitude may be further obtained, and the audio amplification factor may be adjusted according to the amplitude ratio. For example, if the ratio of the third feature input amplitude to the fourth feature input amplitude is 2, the audio amplification factor is doubled, and if the ratio of the third feature input amplitude to the fourth feature input amplitude is 0.5, the audio amplification factor is reduced by 50%.
Through the arrangement, if the sound signal input by the microphone is larger in the actual K song process of the user, the audio amplification factor can be correspondingly increased, and if the sound signal input by the microphone is smaller in the actual K song process of the user, the audio amplification factor can be correspondingly reduced, so that the sound volume of the real song is matched with the sound volume of the lyrics input by the microphone of the user, and finally, the controllability of the audio adjusting method is enhanced.
