The terminal can execute the sound effect adjusting method provided by the invention to adjust the sound effect generated by self playing.
Example 1
Referring to fig. 1, fig. 1 is a flowchart of an embodiment of an audio adjustment method according to the present invention. The sound effect adjusting method provided by the embodiment comprises the following steps:
and S100, when the playing sound of the target terminal is detected, acquiring target audio data in the space where the target terminal is located.
The target terminal is a terminal needing to adjust sound effects, sound played by the target terminal can generate reflection in a space where the target terminal is located to form different sound effects, the sound effects of the sound played by the target terminal in the space where the target terminal is located are required to be adjusted to preset target sound effects, in the prior art, a plurality of terminals are provided with target sound effect modes, sound effect adjusting parameters corresponding to different installation information are built in the terminals, the target sound effects are obtained through multiple tests, a user can feel the best sound effects, when the terminal is in the target sound effect mode, the terminal processes sound data, after the processed audio is played, sound wave signal intensities of sound waves in different frequency bands after being reflected by objects in the space where the terminal is located are changed, and finally the effect of the sound played by the terminal in the space reaches the target sound effects. Different objects have different reflection coefficients for sound waves of different frequencies, so when the installation information of the terminal is different, the reflection conditions for sound waves of different frequencies are different, the terminal needs to perform different processing on sound data to be played according to the sound effect adjusting parameters corresponding to the installation information, for example, signal enhancement is performed to a certain degree in a certain frequency band, and signal attenuation is performed to a certain degree in a certain frequency band, so that the final sound effect which can be heard by a user is the target sound effect.
Specifically, the target audio data is audio data formed by reflecting sound emitted by the target terminal in a space where the target terminal is located, and the method for obtaining the target audio data in the space where the target terminal is located includes:
s110, collecting audio data in a space where a target terminal is located;
s120, filtering the audio data to obtain target audio data, wherein the target audio data does not comprise audio signals except the played sound of the target terminal.
Specifically, the audio data in the space where the target terminal is located may be collected by a far-field microphone set by the target terminal itself, or collected by an audio collecting device in communication with the target terminal and then sent to the target terminal. In addition to the sound emitted by the target terminal, other sounds may exist in the space where the target terminal is located, so in one possible implementation manner, in order to improve accuracy of installation information identification, after the audio data in the space where the target terminal is located is collected, the audio data in the space where the target terminal is located is filtered, so that the target audio data which does not include the audio signal except the playing sound of the target terminal is obtained.

Different installation information can generate different sound effects because reflection coefficients of different materials on sound waves with different frequencies are different. In this embodiment, in order to automatically identify the installation information of the target terminal, thereby implementing an effect of automatically adjusting the sound effect of the target terminal, when the target terminal plays the sound, the target audio data in the space where the target terminal is located is acquired first, and the reflection condition of the sound wave of each frequency band in the space where the target terminal is located can be reflected by the sound wave signal intensity of each frequency band in the target audio data, so that the installation information of the target terminal is identified by the sound wave signal intensity of each frequency band in the target audio data. Each target frequency band in the target audio feature is preset, and the details will be described later.

Specifically, determining the installation information of the target terminal according to the target audio feature difference includes:
and acquiring target installation information corresponding to the target audio differences according to the corresponding relation between each preset audio characteristic difference and the installation information, wherein the target installation information is the installation information of the target terminal.
In this embodiment, what the feature differences corresponding to the different installation information are is predetermined, and the feature differences corresponding to the different installation information are stored as preset audio differences, so that a corresponding relationship between each preset audio feature difference and the installation information is established, after the target audio feature difference is acquired, the installation information corresponding to the target audio difference is determined according to the corresponding relationship, and is used as the installation information of the target terminal.

Specifically, in this implementation manner, determining, according to a plurality of sets of preset data, a correspondence between each preset audio feature difference and installation information includes:
extracting sample target audio features of sample audio data in each set of preset data, and acquiring sample feature differences between the sample target audio features and the preset audio features;

When acquiring the installation information corresponding to the target audio feature difference according to the corresponding relation between each preset audio feature difference and the installation information, the target audio feature difference may not be identical to the preset audio feature difference, and in this embodiment, the installation information corresponding to the preset audio feature difference that is most matched with the target audio feature difference is acquired as the installation information of the target terminal.
Referring to fig. 1 again, the sound effect adjusting method provided in the present embodiment further includes the steps of:
s400, adjusting the sound effect of the target terminal according to the installation information of the target terminal.
Specifically, adjusting the sound effect of the target terminal according to the installation information of the target terminal includes:
s310, determining target sound effect adjusting parameters corresponding to the installation information of the target terminal according to the corresponding relation between the preset installation information and the sound effect adjusting parameters;
