It should be noted that some tags do not belong to an audio file in a certain format, for example, an audio file in MP3 format may have an APEv2 tag.
It should be noted that the audio characteristic parameters of the audio file related in this embodiment may be obtained by using a related technology of speech processing such as speech recognition, which is not limited in this embodiment and is not described herein again.
The technical solution provided in this embodiment can be applied to, but is not limited to, the following scenarios:
1. when the client plays the song according to the local song list stored locally, the equalizing engine in the client acquires the song style of the song according to the label information of the next song to be played. Then, the equalization engine may obtain an equalization parameter corresponding to a song style according to the song style, and may further perform gain adjustment on the audio signal of the song using the equalization parameter. Finally, the client can play the audio signal after the equalization engine adjusts.
2. When a client requests a server to listen to a certain song on line, the server sends the song style of the song to an equalization engine in the client, the equalization engine acquires equalization parameters corresponding to the song style according to the song style, and then gain adjustment can be performed on the audio signal of the listened song by using the equalization parameters. Finally, the client can play the audio signal after the equalization engine adjusts.
3. When a client requests a server to listen to a certain song on line, the server sends the song style of the song to an equalization engine in the server, the equalization engine acquires equalization parameters corresponding to the song style according to the song style, and then gain adjustment can be performed on the audio signal of the listened song by using the equalization parameters. Then, the audio signal after the adjustment by the equalization engine is sent to the client by the server. Finally, the client can play the audio signal after the equalization engine adjusts.
In the embodiment, the song style of the audio file is acquired, and the equalization parameter corresponding to the song style is acquired according to the corresponding relation between the song style and the equalization parameter, so that the audio signal of the audio file can be subjected to gain adjustment by using the equalization parameter without a user participating in the whole adjustment process, the operation is simple, and the efficiency of the gain adjustment of the audio signal is improved.
