Detailed Description
Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present invention are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the invention and should not be taken as limiting the invention with regard to other embodiments that are not detailed herein.
In the description that follows, embodiments of the invention are described with reference to steps and symbols of operations performed by one or more computers, unless otherwise indicated. It will thus be appreciated that those steps and operations, which are referred to herein several times as being computer-executed, include being manipulated by a computer processing unit in the form of electronic signals representing data in a structured form. This manipulation transforms the data or maintains it at locations in the computer's memory system, which may reconfigure or otherwise alter the computer's operation in a manner well known to those skilled in the art. The data maintains a data structure that is a physical location of the memory that has particular characteristics defined by the data format. However, while the principles of the invention have been described in language specific to above, it is not intended to be limited to the specific details shown, since one skilled in the art will recognize that various steps and operations described below may be implemented in hardware.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating an audio processing method according to a first preferred embodiment of the present invention. The audio processing method of the preferred embodiment includes:
step S101, receiving an audio processing instruction;
step S102, acquiring a corresponding audio processing mode according to an audio processing instruction, wherein the audio processing mode comprises relevant parameters for processing audio;
and step S103, processing the audio according to the relevant parameters corresponding to the audio processing mode.
The following describes in detail the specific flow of the steps of the audio processing method of the present preferred embodiment.
In step S101, the terminal receives an audio processing instruction. The terminal may be a mobile phone, a tablet computer, or the like equipped with a microphone and a speaker, and is not limited herein. The audio processing instruction may be generated by the user by clicking an audio processing button, or may be generated automatically by the terminal after the microphone acquires audio. For example, after a user inputs a voice to a microphone of a mobile phone, an audio processing instruction for processing the voice is generated, and then the mobile phone receives the audio processing instruction. Subsequently, the process proceeds to step S102.
In step S102, the terminal obtains a corresponding audio processing mode according to the audio processing instruction, where the audio processing mode includes related parameters for processing audio. Different types of audio are often processed in different ways, and thus it is necessary to process the audio in a targeted manner. For example, from the viewpoint of female and male voices, since the male voice is turned down and the female voice is turned up, a male voice processing mode for processing male audio and a female voice processing mode for processing female audio can be set according to their difference points. Also, as from the music genre, a pop song processing mode for processing for pop songs, a beautiful song processing mode for processing for beautiful songs, and the like can be set. Therefore, the corresponding audio processing mode can be selected according to the type of the audio, and the audio quality is improved. If the existing audio processing mode can not meet the requirements of the user, a user-defined processing mode can be provided, so that the user can determine how to process the audio according to the self requirements.
The relevant parameters in the audio processing mode specifically include a noise reduction parameter, an anti-noise parameter, a volume parameter, a sound equalization parameter, and the like. Specifically, the noise reduction parameter is used for reducing noise of the audio, and can be specifically realized by a Digital Signal Processing (DSP) noise reduction algorithm and other related noise reduction algorithms; the sound equalization parameters can compensate for the imperfections of the loudspeaker and the sound field by adjusting the electrical signals at different frequencies, which can be optimized according to the type of audio. From a musical perspective, a music processing mode optimized specifically for a certain type of music can be formed by modifying the constituent harmonic levels of frequencies in a sound. Only the noise reduction parameters and the sound equalization parameters are described here, and the other parameters are not described one by one.
As for the specific setting method of the parameters, the preferred embodiment specifically describes the setting of the sound equalization parameters, and if a piece of music is male treble, the frequency band in the sound equalization parameters can be set to 164 + 698HZ, and if the piece of music is female treble, the frequency band can be set to 220 + 1100 HZ. In conclusion, the setting of the parameters can not only reduce noise and break sound in the audio, but also process the type of the audio according to the user requirements, thereby improving the quality of the audio. Different audio processing modes can be formed by setting the parameters to be different so as to process the audio. Subsequently, the process proceeds to step S103.
In step S103, finally, the terminal performs corresponding noise reduction, sound breaking removal and other processing on the audio according to the noise reduction parameter, the sound breaking prevention parameter, the volume parameter, the sound equalization parameter and other parameters set by the user in step S102, and finally, the processed high-quality audio is obtained.
The audio processing method of the preferred embodiment generates different audio processing modes by setting the relevant parameters, not only can process the audio according to the type of the audio with pertinence according to the user requirement, but also solves the problems of noise, sound breaking and the like, thereby improving the audio quality.
Example two
Referring to fig. 2, fig. 2 is a flowchart illustrating an audio processing method according to a second preferred embodiment of the present invention. The audio processing method of the preferred embodiment includes:
step S201, receiving an audio processing instruction;
step S202, displaying an audio processing mode selection interface according to the audio processing instruction, wherein the audio processing mode selection interface is used for receiving the audio processing mode selection instruction;
step S203, receiving an audio processing mode selection instruction, and selecting a corresponding audio processing mode from a database according to the audio processing mode selection instruction, wherein the audio processing mode comprises relevant parameters for processing audio;
step S204, if the user selects the custom mode, prompting the user to input related parameters;
step S205, processing the audio according to the relevant parameters corresponding to the audio processing mode.
The following describes in detail the specific flow of the steps of the audio processing method of the present preferred embodiment.
In step S201, the terminal receives an audio processing instruction. The terminal may be a mobile phone, a tablet computer, or the like equipped with a microphone and a speaker, and is not limited herein. The audio processing instruction may be generated by the user by clicking an audio processing button, or may be generated automatically by the terminal after the microphone acquires audio. For example, after a user inputs a voice to a microphone of a mobile phone, an audio processing instruction for processing the voice is generated, and then the mobile phone receives the audio processing instruction. Subsequently, the process proceeds to step S202.
In step S202, the terminal displays an audio processing mode selection interface according to the audio processing instruction, where the audio processing mode selection interface is used to receive the audio processing mode selection instruction. Different types of audio are often processed in different ways, and thus it is necessary to process the audio in a targeted manner. For example, from the viewpoint of female and male voices, since the male voice is turned down and the female voice is turned up, a male voice processing mode for processing male audio and a female voice processing mode for processing female audio can be set according to their difference points. Also, as from the music genre, a pop song processing mode for processing for pop songs, a beautiful song processing mode for processing for beautiful songs, and the like can be set. Therefore, the corresponding audio processing mode can be selected according to the type of the audio, and the audio quality is improved. If the existing audio processing mode can not meet the requirements of the user, a user-defined processing mode can be provided, so that the user can determine how to process the audio according to the self requirements.
Preferably, the audio processing mode selection interface comprises three audio processing modes, namely a male audio processing mode, a female audio processing mode and a custom processing mode, so that the user can select the corresponding audio processing mode according to the gender and the self requirement, and the audio quality is improved. Therefore, when the user inputs a section of lady audio, the audio processing mode selection instruction for carrying out audio processing according to the characteristics of the lady voice is generated by selecting the lady voice processing mode. Subsequently, the process proceeds to step S203.
In step S203, the terminal receives an audio processing mode selection instruction, and selects a corresponding audio processing mode from the database according to the audio processing mode selection instruction, where the audio processing mode includes parameters related to audio processing. The relevant parameters in the audio processing mode specifically include a noise reduction parameter, an anti-noise parameter, a volume parameter, a sound equalization parameter, and the like. Specifically, the noise reduction parameter is used for reducing noise of the audio, and can be specifically realized by a Digital Signal Processing (DSP) noise reduction algorithm and other related noise reduction algorithms; the sound equalization parameters can compensate for the imperfections of the loudspeaker and the sound field by adjusting the electrical signals at different frequencies, which can be optimized according to the type of audio. From a musical perspective, a music processing mode optimized specifically for a certain type of music can be formed by modifying the constituent harmonic levels of frequencies in a sound. Only the noise reduction parameters and the sound equalization parameters are described here, and the other parameters are not described one by one.
As for the specific setting method of the parameters, the preferred embodiment specifically describes the setting of the sound equalization parameters, and if a piece of music is male treble, the frequency band in the sound equalization parameters can be set to 164 + 698HZ, and if the piece of music is female treble, the frequency band can be set to 220 + 1100 HZ. In conclusion, the setting of the parameters can not only reduce noise and break sound in the audio, but also process the type of the audio according to the user requirements, thereby improving the quality of the audio. Different audio processing modes can be formed by setting the parameters to be different so as to process the audio.
The database is preset by the terminal. Specifically, the terminal firstly acquires the audio processing mode, then acquires the related parameters corresponding to the audio processing mode, and finally establishes the association storage of the audio processing mode, the related parameters and the association relation of the audio processing mode and the related parameters so as to establish the database.
Preferably, the terminal can also automatically identify the audio input by the user, for example, when the female voice is identified, the generated audio processing instruction can carry the female voice information, and the terminal automatically selects the female voice processing mode from the database according to the female voice information, so that the intelligence of audio processing is improved. Subsequently, the process proceeds to step S204.
In step S204, if the user selects the custom mode in step S203, the terminal prompts the user to input related parameters, so that the user can set parameter values such as noise reduction, sound breaking prevention, volume, sound balance and the like according to the user' S own requirements, thereby determining how to process the audio. For example, if the user desires the audio to be rich and the perception of rich, the frequency band may be modulated by 60-100 Hz. Subsequently, the process proceeds to step S205.
In step S205, the terminal performs corresponding noise reduction and noise breaking removal on the audio according to the noise reduction parameter, the anti-break parameter, the volume parameter, the sound equalization parameter, and other parameters set by the user in step S204, and finally obtains a processed high-quality audio.
On the basis of the first preferred embodiment, the audio processing method of the preferred embodiment generates different audio processing modes by further setting the relevant parameters, so that the audio can be processed in a targeted manner according to the user requirements, and the problems of noise, sound breaking and the like are solved, thereby further improving the audio quality.

When the audio processing device 30 of the preferred embodiment is used, the audio processing instruction receiving module 301 receives an audio processing instruction. The audio processing instruction may be generated by the user by clicking an audio processing button, or may be automatically generated after the microphone acquires audio. For example, after a user inputs a voice to a microphone of a mobile phone, an audio processing instruction for processing the voice is generated, and then the audio processing instruction receiving module 301 in the mobile phone receives the audio processing instruction. The audio processing mode acquisition module 302 is then invoked.
Then, the audio processing mode obtaining module 302 obtains a corresponding audio processing mode according to the audio processing instruction, where the audio processing mode includes related parameters for processing audio. Different types of audio are often processed in different ways, and thus it is necessary to process the audio in a targeted manner. For example, from the viewpoint of female and male voices, since the male voice is turned down and the female voice is turned up, a male voice processing mode for processing male audio and a female voice processing mode for processing female audio can be set according to their difference points. Also, as from the music genre, a pop song processing mode for processing for pop songs, a beautiful song processing mode for processing for beautiful songs, and the like can be set. In this way, the audio processing mode obtaining module 302 can select a corresponding audio processing mode according to the type of the audio, thereby improving the audio quality. If the existing audio processing mode can not meet the requirements of the user, a user-defined processing mode can be provided, so that the user can determine how to process the audio according to the self requirements.
The relevant parameters in the audio processing mode specifically include a noise reduction parameter, an anti-noise parameter, a volume parameter, a sound equalization parameter, and the like. Specifically, the noise reduction parameter is used for reducing noise of the audio, and can be specifically realized by a Digital Signal Processing (DSP) noise reduction algorithm and other related noise reduction algorithms; the sound equalization parameters can compensate for the imperfections of the loudspeaker and the sound field by adjusting the electrical signals at different frequencies, which can be optimized according to the type of audio. From a musical perspective, a music processing mode optimized specifically for a certain type of music can be formed by modifying the constituent harmonic levels of frequencies in a sound. Only the noise reduction parameters and the sound equalization parameters are described here, and the other parameters are not described one by one.
As for the specific setting method of the parameters, the preferred embodiment specifically describes the setting of the sound equalization parameters, and if a piece of music is male treble, the frequency band in the sound equalization parameters can be set to 164 + 698HZ, and if the piece of music is female treble, the frequency band can be set to 220 + 1100 HZ. In conclusion, the setting of the parameters can not only reduce noise and break sound in the audio, but also process the type of the audio according to the user requirements, thereby improving the quality of the audio. Different audio processing modes can be formed by setting the parameters to be different so as to process the audio. The audio processing module 303 is then invoked.
Finally, the audio processing module 303 performs corresponding noise reduction, sound breaking removal and other processing on the audio according to the set noise reduction parameters, sound breaking prevention parameters, volume parameters, sound balance parameters and other parameters, and finally obtains the processed high-quality audio.
This completes the audio processing process of the audio processing apparatus 30 of the preferred embodiment.
The audio processing device of the preferred embodiment generates different audio processing modes by setting the relevant parameters, can process audio in a targeted manner according to the user requirements, and also solves the problems of noise, sound breaking and the like, thereby improving the audio quality.

On the basis of the first preferred embodiment, the preferred embodiment is expanded and refined, wherein the related parameter input prompting module 403 is used for prompting the user to input related parameters when the user selects a custom mode; the audio processing mode selection interface display unit 4021 is configured to display an audio processing mode selection interface according to the audio processing instruction, where the audio processing mode selection interface is configured to receive the audio processing mode selection instruction; the audio processing mode selecting unit 4022 is configured to receive an audio processing mode selecting instruction, and select a corresponding audio processing mode from the database according to the audio processing mode selecting instruction.
When the audio processing apparatus 40 of the preferred embodiment is used, the audio processing instruction receiving module 401 first receives an audio processing instruction. The audio processing instruction may be generated by the user by clicking an audio processing button, or may be generated automatically by the terminal after the microphone acquires audio. For example, after a user inputs a voice to a microphone of a mobile phone, an audio processing instruction for processing the voice is generated, and then the audio processing instruction receiving module 401 in the mobile phone receives the audio processing instruction. The audio processing mode acquisition module 402 is then invoked.
Then, the audio processing mode selection interface display unit 4021 in the audio processing mode acquisition module 402 displays an audio processing mode selection interface according to the audio processing instruction, where the audio processing mode selection interface is configured to receive the audio processing mode selection instruction. Different types of audio are often processed in different ways, and thus it is necessary to process the audio in a targeted manner. For example, from the viewpoint of female and male voices, since the male voice is turned down and the female voice is turned up, a male voice processing mode for processing male audio and a female voice processing mode for processing female audio can be set according to their difference points. Also, as from the music genre, a pop song processing mode for processing for pop songs, a beautiful song processing mode for processing for beautiful songs, and the like can be set. Therefore, the corresponding audio processing mode can be selected according to the type of the audio, and the audio quality is improved. If the existing audio processing mode can not meet the requirements of the user, a user-defined processing mode can be provided, so that the user can determine how to process the audio according to the self requirements.
Preferably, the audio processing mode selection interface displayed by the audio processing mode selection interface display unit 4021 includes three audio processing modes, namely a male audio processing mode, a female audio processing mode, and a custom processing mode, so that the user can select the corresponding audio processing mode according to the gender and the self-requirement, thereby improving the audio quality. Therefore, when the user inputs a section of lady audio, the audio processing mode selection instruction for carrying out audio processing according to the characteristics of the lady voice is generated by selecting the lady voice processing mode. Then, the audio processing mode selecting unit 4022 in the processing mode acquiring module 402 is called.
Next, the audio processing mode selecting unit 4022 receives an audio processing mode selecting instruction, and selects a corresponding audio processing mode from the database according to the audio processing mode selecting instruction, where the audio processing mode includes parameters related to audio processing. The relevant parameters in the audio processing mode specifically include a noise reduction parameter, an anti-noise parameter, a volume parameter, a sound equalization parameter, and the like. Specifically, the noise reduction parameter is used for reducing noise of the audio, and can be specifically realized by a Digital Signal Processing (DSP) noise reduction algorithm and other related noise reduction algorithms; the sound equalization parameters can compensate for the imperfections of the loudspeaker and the sound field by adjusting the electrical signals at different frequencies, which can be optimized according to the type of audio. From a musical perspective, a music processing mode optimized specifically for a certain type of music can be formed by modifying the constituent harmonic levels of frequencies in a sound. Only the noise reduction parameters and the sound equalization parameters are described here, and the other parameters are not described one by one.
As for the specific setting method of the parameters, the preferred embodiment specifically describes the setting of the sound equalization parameters, and if a piece of music is male treble, the frequency band in the sound equalization parameters can be set to 164 + 698HZ, and if the piece of music is female treble, the frequency band can be set to 220 + 1100 HZ. In conclusion, the setting of the parameters can not only reduce noise and break sound in the audio, but also process the type of the audio according to the user requirements, thereby improving the quality of the audio. Different audio processing modes can be formed by setting the parameters to be different so as to process the audio. It should be noted that the database is preset by the audio processing mode obtaining module 402. Specifically, the audio processing mode obtaining module 402 first obtains the audio processing mode, then obtains the related parameters corresponding to the audio processing mode, and finally establishes the association storage of the audio processing mode, the related parameters, and the association relationship between the two to establish the database.
Preferably, the terminal may further automatically identify the audio input by the user, for example, when the female voice is identified, the generated audio processing instruction may carry information of the female voice, and the audio processing mode obtaining module 402 automatically selects the female voice processing mode from the database according to the information of the female voice, so as to improve the intelligence of audio processing. The relevant parameter input prompt module 403 is then invoked.
Next, if the audio processing mode obtaining module 402 selects the custom mode, the related parameter input prompting module 403 prompts the user to input the related parameter, so that the user can set the parameter values of noise reduction, sound breaking prevention, volume, sound balance, and the like according to the user's own requirement, thereby determining how to process the audio. For example, if the user desires the audio to be rich and the perception of rich, the frequency band may be modulated by 60-100 Hz. The audio processing module 404 is then invoked.
Finally, the audio processing module 404 performs corresponding noise reduction, sound breaking removal and other processing on the audio according to the noise reduction parameter, the sound breaking prevention parameter, the volume parameter, the sound equalization parameter and other parameters set by the user, and finally obtains the processed high-quality audio.
