Some terms involved in the present application are explained first.

Equalizer (Equalizer): is an audio processing device for adjusting the volume or tone of different frequency ranges and typically comprises a plurality of frequency bands, each band having a gain control that can either increase or decrease the volume of the band.

As described in the background art, the equalizer currently in common use includes a multi-segment equalizer and a wind format equalizer, and a user can adjust the equalizer according to his own preference and requirement to generate a custom audio curve.

Referring to fig. 1, fig. 1 is a schematic diagram of a conventional multi-segment equalizer. The multi-segment equalizer can adjust the volume or tone in different frequency ranges, usually including low frequency, intermediate frequency, high frequency, etc., and each frequency band has a gain control, so that the volume of the frequency band can be increased or decreased. The multistage equalizer has higher use threshold, and the common user can not accurately perform the overall balanced adjustment aiming at the hardware equipment of the sound system according to the individual listening requirement.

Referring to fig. 2, fig. 2 is a schematic diagram of a conventional style equalizer. The style equalizer can simulate different music styles, such as rock, classical, popular and the like, and preset different frequency band gain and attenuation parameters based on the characteristics of the different music styles, so that a user can realize the adjustment of the audio effect by selecting different style modes. But a style equalizer cannot simultaneously satisfy a plurality of sound sources, for example, after selecting a rock style, the requirement of a movie scene may not be satisfied.

In order to solve the above problems, the present application provides an audio curve generating method, an electronic device, a driving device, and a storage medium.

Referring to fig. 3, fig. 3 is a schematic flow chart of main steps of an audio curve generating method according to an embodiment of the present application. The audio curve generation method provided by the application is applied to an equalizer (such as an on-vehicle equalizer, a household equalizer and the like), and a plurality of sound sources are prestored in the equalizer.

As shown in fig. 3, the audio curve generating method in the embodiment of the present application mainly includes the following steps S301 to S303.

Step S301: processing the multiple sound sources to obtain multiple sections of audio corresponding to each sound source;

step S302: responding to the audio curve generation instruction, and providing a plurality of sections of audio corresponding to each sound source for a user to select;

step S303: and generating a user-specific audio curve based on the selection results of all the sound sources.

Based on the methods described in the steps S301 to S303, the dedicated audio curve can be adaptively generated according to the selection of the user, so that compared with a multi-segment equalizer, the method reduces the use threshold, and the user can easily get up with the hand; compared with a wind format equalizer, the system can provide personalized and customized service for users, and simultaneously can enable the adjusted audio curves to better represent various types of sound sources according to listening preference of the users under constant sound system hardware.

The following further describes the steps S301 to S303.

In some embodiments of step S301, the equalizer pre-stores a plurality of sound sources, such as 6-10 kinds, and may specifically include natural environment sound sources (such as rain, wind, and running water), artificial environment sound sources (such as mechanical sound and human sound), musical instrument sound sources (such as piano sound, guitar sound, drum sound, and string instrument sound), and the like, which are not limited herein.

Further, each audio source contains a plurality of frequency bands. Taking the sound information of the full frequency band which can be heard by the human ear as an example, the 20Hz-20000Hz can be processed in a shelf mode, and the full frequency band coverage is ensured.

The shelf type processing is a common frequency equalizer processing mode, and the principle of the shelf type processing is that the whole frequency response curve is divided into a plurality of frequency bands, and then each frequency band is subjected to independent gain or attenuation processing, so that the whole frequency response curve is flatter or more satisfactory. By the shelf processing, the audio processing can be made finer and more efficient, avoiding problems with certain frequency ranges being ignored or oversrocessed.

Specifically, the frequency range of 20Hz-20000Hz can be divided into three frequency bands of low frequency, intermediate frequency and high frequency, and can be also divided into seven frequency bands of ultra-low frequency, medium-low frequency, intermediate frequency, medium-high frequency, high frequency and ultra-high frequency.

Further, if divided into three frequency bands, the low frequency can be 20Hz-500Hz, the intermediate frequency can be 500Hz-2000Hz, and the high frequency can be 2000Hz-20000Hz.

If the frequency band is divided into seven frequency bands, the ultra-low frequency can be 20Hz-60Hz, the low frequency can be 60Hz-250Hz, the medium and low frequency can be 250Hz-500Hz, the medium frequency can be 500Hz-2000Hz, the medium and high frequency can be 2000Hz-4000Hz, the high frequency can be 4000Hz-6000Hz, and the ultra-high frequency can be 6000Hz-20000Hz.

It should be noted that the above examples and divisions of a plurality of frequency bands are only illustrative, and in practical applications, each of the audio sources pre-stored in the equalizer may include some or all of the frequency bands, so long as all of the audio sources are ensured to cover the full frequency band of 20Hz-20000Hz, and those skilled in the art may set and adjust the audio sources according to specific situations, which is not limited herein.

Further, in some embodiments of step S301, frequency response processing may be performed on a plurality of frequency bands of each audio source, so as to obtain a plurality of audio segments corresponding to each audio source. The frequency response process adjusts the frequency response by adjusting the gain or attenuation in different frequency ranges to improve the audio quality.

In some embodiments, a plurality of frequency bands may be selected for each audio source, and gain processing and/or attenuation processing and/or removal processing may be performed on the selected plurality of frequency bands, respectively.

Specifically, the volume gain processing and/or the volume attenuation processing may be performed on the plurality of frequency bands based on the characteristics of each sound source and the preset volume compensation interval, and the frequency band removal processing may also be performed on the plurality of frequency bands.

That is, the volume gain process and/or the volume attenuation process of a specific Q value is performed for a plurality of frequency bands based on the characteristics of each sound source and a preset volume compensation section, or the specific frequency band removal process is performed based on the characteristics of each sound source.

The specific Q value represents a specific frequency range, and in practical application, the specific Q value may be a certain frequency band, or the specific frequency range may be set according to specific requirements, which is not limited herein.

The preset volume compensation interval can be [ -3dB, +3dB ], [ -3dB, +6dB ], [ -6dB, +6dB ] and the like; the characteristics of each sound source refer to the unique sound characteristics and expression modes of the sound source, and different sound sources, such as human voice, musical instruments, natural sound and the like, are different in terms of frequency distribution, harmonic structures, time domain characteristics and the like, and the differences are the characteristics of each sound source.

For example, the frequency range of the voice is mainly concentrated in the middle frequency and the high frequency, so that when a plurality of frequency bands of the voice source are processed, gain processing can be performed on the low frequency, and weakening processing can be performed on the high frequency, so that the voice is clearer and brighter; the frequency range of the guitar is mainly concentrated in the middle-low frequency range, so that when a plurality of frequency ranges of the guitar sound source are processed, gain processing can be performed on the middle-low frequency range, and the brightness and definition of guitar sound are enhanced.

It should be noted that when processing multiple audio sources pre-stored in the equalizer, the processing modes of the multiple audio sources should be different, so as to ensure that more comprehensive audio is obtained.

In some embodiments, taking a flowing water sound source pre-stored in an equalizer as an example, the frequency range of the flowing water sound is wider, and the flowing water sound source comprises a plurality of frequency bands such as a low frequency band, an intermediate frequency band and a high frequency band, so that three frequency bands can be selected, and frequency response processing is respectively performed on the three frequency bands, such as volume gain processing is performed on the low frequency band, the low frequency band is +6dB, volume attenuation processing is performed on the intermediate frequency band, frequency band removal processing is performed on the intermediate frequency band-3 dB, and the high frequency band is removed, thereby obtaining three sections of audio corresponding to the flowing water sound source, which are respectively recorded as flowing water sound 1, flowing water sound 2 and flowing water sound 3.

In some embodiments, taking a drum sound source pre-stored in an equalizer as an example, the drum sound includes a big drum sound, a small drum sound, a cymbal sound, and the like, the frequency range is wider, three frequency bands including an ultralow frequency band, a medium low frequency band and a medium high frequency band can be selected, and frequency response processing is respectively performed on the three frequency bands, for example, volume gain processing is respectively performed on the ultralow frequency band, the medium low frequency band and the medium high frequency band, the ultralow frequency band +3dB, the medium low frequency +3dB and the medium high frequency +3dB, so that three audio segments corresponding to the drum sound source are obtained and respectively recorded as a drum sound audio 1, a drum sound audio 2 and a drum sound audio 3.

It should be noted that the above examples of the frequency response processing for a plurality of frequency bands of each audio source are only illustrative, and in practical application, those skilled in the art may set the frequency response processing according to a specific scenario, which is not limited herein.

The frequency response processing is carried out according to the characteristics of each sound source, so that the tone quality can be improved, the audio signal is clearer and more natural, distortion and noise caused by over-emphasis or weakening of certain frequency bands are avoided, and the expressive force, the spatial sense and the stereoscopic sense of sound can be enhanced.

The above is a further explanation of step S301, and the following further explanation of step S302 is continued.

In some embodiments of step S302, when the user needs the equalizer to generate the user-specific audio curve, the user may find the audio curve generating key on the display interface of the equalizer to send the audio curve generating instruction, or may use the voice function of the equalizer to send the audio curve generating instruction, and after receiving the instruction from the user, the equalizer may provide multiple pieces of audio corresponding to each audio source for the user to select.

Specifically, the equalizer may display multiple pieces of audio corresponding to each audio in turn based on a preset sequence of multiple audio sources, for selection by a user.

For example, the equalizer pre-stores 6 sound sources, namely, a flowing water sound source, a drum sound source, a mechanical sound source, an amorous sound source, a piano sound source and a human sound source, so that multiple pieces of audio corresponding to each sound source can be displayed in sequence according to a preset sequence, such as the sequence of the flowing water sound source, the drum sound source, the mechanical sound source, the amorous sound source, the piano sound source and the human sound source, and the user can select the audio.

In some implementations, referring to fig. 4, fig. 4 is a schematic diagram of an equalizer display interface according to one embodiment of the present application. As shown in fig. 4, the user may play a plurality of pieces of audio corresponding to each of the audio segments and select the favorite audio until all the audio segments are selected.

The above is a further explanation of step S302, and the following further explanation of step S303 is continued.

In some embodiments of step S303 described above, an initial audio profile, also referred to as a "reference profile" or "standard profile" is preset in the equalizer, and is typically set by an audio engineer or manufacturer based on experience and multiple test results.

After the user selects a certain piece of audio for each of the sound sources, the initial audio profile may be adjusted based on the user's selection of each of the sound sources.

Specifically, the initial audio profile may be subjected to a corresponding frequency response process based on the selection result of each of the sound sources.

For example, when the user selects the streaming sound audio 2 from the three audio segments corresponding to the streaming sound source, the user is shown to prefer the hearing sense that the intermediate frequency is pulled down, so that the intermediate frequency in the initial audio curve can be subjected to volume weakening processing, and particularly the intermediate frequency can be reduced by-3 dB according to the streaming sound audio 2.

When the user selects the drumbeat audio 1 from the three audio segments corresponding to the drumbeat audio source, the user is shown to prefer the hearing sensation of the promotion of the ultra-low frequency band, so that the ultra-low frequency in the initial audio curve can be subjected to volume gain processing, and particularly the ultra-low frequency +3dB can be generated according to the drumbeat audio 1.

And obtaining the user-specific audio curve until the initial audio curve is adjusted based on the selection results of all the sound sources.

Specifically, the user can select 6-10 times according to 6-10 sound sources pre-stored in the equalizer, and all sound sources of one user are ensured to be selected to cover 20Hz-20000Hz full frequency range.

In some embodiments, if the user selects the mechanical audio 2 with volume gain processing (middle and high frequency +6db) for the middle and high frequency in the multiple pieces of audio corresponding to the mechanical audio source, the volume gain processing will be performed for the middle and high frequency in the initial audio curve, such as middle and high frequency +6db. On the basis, if the user selects the piano sound frequency 3 which performs the volume weakening process (middle-high frequency-2 dB) on the middle-high frequency in the multiple pieces of audios corresponding to the subsequent piano sound sources, the volume weakening process can be performed on the middle-high frequency which has performed the volume gain process in the initial audio curve.

Specifically, the result of the two selections of the user can be synthesized to be-2 dB on the basis of +6dB of the medium-high frequency, so that the medium-high frequency of +4dB is obtained; and the medium-high frequency in the initial audio curve can be subjected to volume weakening processing only based on the later selection result of the user, so that the medium-high frequency of-2 dB can be directly obtained. In practical applications, those skilled in the art may set the settings according to specific situations and requirements, which are not limited herein.

Further, after the user selects all the sound sources, a user-specific audio curve can be obtained.

Referring to fig. 5, fig. 5 is a schematic diagram of a user-specific audio profile according to one embodiment of the present application. As shown in FIG. 5, the audio curve has an abscissa of frequency (in Hz) and an ordinate of sound compensation (in dB).

By the audio curve generation method, the exclusive audio curve can be adaptively generated according to the selection of the user, and compared with a multi-section equalizer, the audio curve generation method has the advantages that the use threshold is reduced, and the user can get up more easily; compared with a wind format equalizer, the system can provide personalized and customized service for users, and simultaneously can enable the adjusted audio curves to better represent various types of sound sources according to listening preference of the users under constant sound system hardware.
