The present invention is not particularly limited herein.
It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, fig. 2 shows 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 step 201, audio to be processed is acquired.
In the present embodiment, the execution subject of the audio processing method (e.g., the terminal devices 101, 102, 103 shown in fig. 1) can acquire audio to be processed in various ways. For example, the executing body may record the singing voice of the user through the recording device to obtain the audio to be processed. The recording device may be integrated on the execution body, or may be in communication connection with the execution body, which is not limited in the present invention. For another example, the executing body may also obtain pre-stored audio from a local or other storage device in communication connection as the audio to be processed.
In this embodiment, the audio to be processed may be arbitrary audio. The determination of the audio to be processed can be specified by a technician or can be obtained by screening according to a certain condition. For example, when the user sings through the terminal device (e.g., a smart phone), the audio to be processed may be the complete audio singed by the user, or may be an audio clip singed by the user. In a real-time listening scenario, the audio to be processed may also be a short (e.g. 30 ms) piece of audio that the user sings. It should be noted that, the audio to be processed may be the original audio sung by the user, or may be the audio after the original audio is processed to a certain extent.
In this embodiment, the execution body may perform audio characteristic analysis on the audio to be processed in various manners to obtain audio characteristic data, and display the audio characteristic data. As an example, some existing audio processing software or open source kits may be utilized to extract various characteristics of the audio to be processed. As an example, various characteristics of the audio to be processed may also be extracted using various algorithms (e.g., fourier transforms) that exist. Wherein the audio characteristic data includes, but is not limited to: spectrum, spectrum center point, spectrum differential amplitude, signal to noise ratio, spectrum cut-off spectrum, etc. On this basis, audio characteristic data obtained by various means can be displayed by a display device. The display device may be integrated into the execution body or may be in communication with the execution body. The present invention is not particularly limited thereto. In addition, the execution subject 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. The audio characteristic data may also be presented in the form of an operative graphical interface, as an example.
In step 203, in response to receiving the target audio characteristic data obtained after the user adjusts the audio characteristic data, it is determined whether the target audio characteristic data is within a preset threshold range.
In this embodiment, in response to receiving target audio characteristic data obtained after the user adjusts the audio characteristic data, the execution body may determine whether the target audio characteristic data is within a preset threshold range. In practice, the user may adjust the audio characteristic data according to the need on the basis of presenting the audio characteristic data of the audio to be processed in step 202. So that the execution subject 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, step 204 may continue to be performed.
In some optional implementations 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 subjected to the equalization processing.
In step 204, in response to determining that the target audio characteristic data is not within the threshold range, the target audio characteristic data is adjusted, and the audio to be processed is subjected to equalization processing 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 above-described execution subject may adjust the target audio characteristic data in various ways. As an example, data exceeding the above threshold range among 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 the present embodiment, the audio characteristic data comprises a frequency spectrum, and in response to determining that the target audio characteristic data is not within the threshold range, adjusting the target audio characteristic data comprises: in response to determining that the frequency spectrum of the target audio characteristic data includes frequency components greater than a preset upper frequency threshold, removing frequency components greater than the upper frequency threshold from the frequency spectrum of the target audio characteristic data.
In some optional implementations of the present embodiment, in response to determining that the target audio characteristic data is not within the threshold range, adjusting the target audio characteristic data further comprises: in response to determining that the frequency spectrum of the target audio characteristic data includes frequency components less than a preset lower frequency threshold, removing frequency components less than the lower frequency threshold in the frequency spectrum of the target audio characteristic data.
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 the smartphone 301. The smartphone 301 first acquires the audio 3011 to be processed. Then, audio characteristics analysis is performed on the audio 3011 to be processed, and audio characteristic data 3012 is obtained. And presents the audio characteristic data 3012. In response to receiving target audio characteristic data 3013, which is obtained after the user adjusts for 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 3011 to be processed is subjected to equalization processing based on the adjusted target audio characteristic data, i.e., 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 the audio to be processed to obtain audio characteristic data, and displaying the audio characteristic data; determining whether the target audio characteristic data is within a preset threshold value range or not in response to receiving the target audio characteristic data obtained after the user adjusts the audio characteristic data; and 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 process, the target audio characteristic data is adjusted, so that the influence on the equalization processing effect due to the fact that the target audio characteristic exceeds a preset range is avoided. Therefore, the parameter balance adjustment can be realized on the basis of the graphic balance. Two balanced 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 includes the steps of:
in step 401, audio to be processed is acquired.
In response to determining that the target audio characteristic data is not within the threshold range, step 404, the target audio characteristic data is adjusted.
In this embodiment, the specific implementation of steps 401 to 404 and the technical effects thereof may refer to steps 201 to 204 in the corresponding embodiment of fig. 2, which are not described herein again.
In this embodiment, the execution subject of the audio processing method may display the graphic equalizing 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 subject may perform the 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 class information. Specifically, the equalization algorithm may be classified into different categories in advance according to a certain index (for example, different types of filters used). And displays category information of these categories. And then, the parameters of the filter corresponding to the filter category information selected by the user can be adjusted through the adjusted target audio characteristic data. The audio to be processed is then processed through a filter.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the audio processing method in this embodiment adds a step of performing equalization processing on the audio to be processed according to the equalization algorithm type information selected by the user in the displayed graphical equalization interface. Thereby increasing the flexibility and the selectivity of the equalization process.
With further reference to fig. 5, as an implementation of the method shown in the foregoing figures, the present invention provides an audio processing apparatus, an embodiment of which corresponds to the method embodiment shown in fig. 2, and which is particularly applicable to various electronic devices.
