With continued reference to fig. 2, fig. 2 illustrates a flow 200 of one embodiment of an audio processing method according to the present invention. The audio processing method comprises the following steps:
In the present embodiment, the execution subject of the audio processing method (e.g., the terminal apparatuses 101, 102, 103 shown in fig. 1) may acquire the audio to be processed in various ways. For example, the executing body may record the voice sung by the user through a recording device to obtain the audio to be processed. The recording device may be integrated on the execution main body, or may be in communication connection with the execution main body, which is not limited in the present invention. For another example, the execution main body may also obtain pre-stored audio from a local or other storage device connected in communication as the audio to be processed.
In the present embodiment, the audio to be processed may be arbitrary audio. The determination of the audio to be processed may be specified by a technician, or may be obtained by screening according to a certain condition. For example, when a user sings through a terminal device (e.g., a smartphone), the audio to be processed may be the complete audio that the user sings, or may be an audio clip that the user sings. In the real-time listening scenario, the audio to be processed may also be an audio clip with a short singing time (e.g., 30 ms) of the user. It should be noted that the audio to be processed may be an original audio that is recorded and sung by the user, or may be an audio obtained by performing a certain processing on the original audio.
In this embodiment, the execution main body may perform audio characteristic analysis on the audio to be processed in various ways, obtain audio characteristic data, and display the audio characteristic data. As an example, various characteristics of the audio to be processed may be extracted using some existing audio processing software or an open source toolkit. As an example, the extraction of various characteristics of the audio to be processed may also be performed using various existing algorithms (e.g., fourier transform). The audio characteristic data includes, but is not limited to: spectrum, spectral center point, spectral difference amplitude, signal-to-noise ratio, spectral cutoff spectrum, and the like. On the basis, the audio characteristic data obtained in various ways can be displayed through the display device. The display device can be integrated in the execution main body or can be in communication connection with the execution main body. The present invention is not particularly limited. In addition, the execution body may present the audio characteristic data in various forms. As an example, the audio characteristic data may be presented in the form of a waveform diagram. By way of example, the audio characteristic data may also be presented in the form of an operative graphical interface.
In this embodiment, in response to receiving the target audio characteristic data obtained by adjusting the audio characteristic data by the user, the executing entity may determine whether the target audio characteristic data is within a preset threshold range. In practice, on the basis of displaying the audio characteristic data of the audio to be processed in step 202, the user may adjust the audio characteristic data as needed. So that the execution body can obtain the target audio characteristic data. On this basis, the execution subject may determine whether the target audio characteristic data is within a preset threshold range. If it is determined that the target audio characteristic data is not within the preset threshold range, execution may continue with step 204.
In some optional implementation manners of this embodiment, if it is determined that the target audio characteristic data is within the preset threshold range, the audio to be processed may be directly equalized.
And step 204, in response to determining that the target audio characteristic data is not within the threshold range, adjusting the target audio characteristic data, and performing equalization processing on the audio to be processed based on the adjusted target audio characteristic data.
In the present embodiment, in response to determining that the target audio characteristic data is not within the threshold range, the execution subject described above may adjust the target audio characteristic data in various ways. As an example, data out of the above-described threshold range in the target audio characteristic data may be deleted. As an example, data that is not within the threshold range may also be adjusted to be within the threshold range.
In some optional implementations of this embodiment, the audio characteristic data includes a frequency spectrum, and adjusting the target audio characteristic data in response to determining that the target audio characteristic data is not within the threshold range includes: in response to determining that the frequency spectrum of the target audio characteristic data includes frequency components greater than a preset upper frequency threshold, frequency components greater than the upper frequency threshold in the frequency spectrum of the target audio characteristic data are removed.
In some optional implementations of this embodiment, in response to determining that the target audio characteristic data is not within the threshold range, adjusting the target audio characteristic data further includes: and removing frequency components smaller than a lower limit frequency threshold in the frequency spectrum of the target audio characteristic data in response to determining that the frequency spectrum of the target audio characteristic data includes frequency components smaller than the preset lower limit frequency threshold.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the audio processing method according to the present embodiment. In the application scenario of fig. 3, the execution subject of the audio processing method may be a smartphone 301. The smartphone 301 first obtains the to-be-processed audio 3011. Then, audio characteristic analysis is performed on the audio 3011 to be processed, resulting in audio characteristic data 3012. And presenting the audio characteristic data 3012. In response to receiving the target audio characteristic data 3013 adjusted by the user with respect to the audio characteristic data 3012, the smartphone 301 may determine whether the target audio characteristic data 3013 is within a preset threshold range. In response to determining that the target audio characteristic data 3013 is not within the threshold range, the target audio characteristic data 3013 is adjusted, and the audio to be processed 3011 is subjected to equalization processing based on the adjusted target audio characteristic data, i.e., the new target audio characteristic data 3014.
The method provided by the embodiment of the invention comprises the steps of firstly carrying out audio characteristic analysis on audio to be processed to obtain audio characteristic data, and displaying the audio characteristic data; in response to receiving target audio characteristic data obtained after a user adjusts the audio characteristic data, determining whether the target audio characteristic data is within a preset threshold range; and adjusting the target audio characteristic data in response to determining that the target audio characteristic data is not within the threshold range, and performing equalization processing on the audio to be processed based on the adjusted target audio characteristic data. In the process, the target audio characteristic data is adjusted, so that the influence on the equalization processing effect caused by the fact that the target audio characteristic exceeds a preset range is avoided. Thus, parameter equalization adjustment can be realized on the basis of the illustrated equalization. Two equilibrium adjustment modes are convenient to use simultaneously.
With further reference to fig. 4, a flow 400 of yet another embodiment of an audio processing method is shown. The flow 400 of the audio processing method comprises the following steps:

In the present embodiment, the execution subject of the audio processing method may display the graphic equalization interface through the display device. Therefore, the user can select the equalization algorithm category information displayed in the graphical equalization interface by executing preset operation. On this basis, the execution main body may perform equalization processing on the audio to be processed based on the adjusted target audio characteristic data and the equalization algorithm indicated by the equalization algorithm category information. Specifically, the equalization algorithms may be classified into different categories according to a certain index (for example, the type of filter used is different). And displays the category information of these categories. And then, adjusting the parameters of the filter corresponding to the filter type information selected by the user through the adjusted target audio characteristic data. Then, the audio to be processed is processed by a filter.
