Embodiment Construction
[0049]The present invention provides a method and device for adjusting the volume output value of audio data based on the technology of comparing the genre characteristic information of the audio data to be played with the currently played audio data. Utilizing the method and device of the present invention, when the user is listening to music, if the currently played song belongs to a soft style, the volume used by the user is relatively high; If the next piece of music is relatively high-pitched, the volume will be automatically lowered to a volume suitable for the human ear after the current music is played and before the next piece of music is played, so as to prevent the user's hearing from being damaged. The technical content of the present invention will be described in detail below in conjunction with various embodiments.
[0050] like figure 1 As shown, a method for adjusting the volume output value of audio data provided in this embodiment includes:

The invention provides a method and a device for regulating a sound volume output value of audio data. The method includes the steps of: reading audio data to be played and currently-played audio data; extracting music style feature information of the audio data to be played and the currently-played audio data; comparing the music style feature information of the audio data to be played with that of the currently-played audio data; determining a music style type of the audio data to be played relative to the currently-played audio data according to a comparison result; calculating a sound volume gain value relative to a sound volume output value of the currently-played audio data according to the determined music style type; and regulating the sound volume output value of the audio data to be played according to the sound volume gain value after the playing of the currently-played audio data is stopped. According to the invention, how to automatically regulate the sound volume output of different types of audio files is solved, and the output sound volume of the audio files can be regulated according to a practical situation of currently-played music.
Description
technical field [0001] The present invention relates to a volume management method and system, in particular to a method, device and terminal for adjusting the volume output value of audio data after comparing with the currently playing audio. Background technique [0002] When existing mobile terminals or multimedia players play music, users generally use earphones or loudspeakers when listening to music. Soft and then a high-pitched song, if the volume remains constant, it will damage the user's hearing and bring a bad experience to the user. [0003] The prior art adopts the following method when solving this type of problem: by obtaining the tag data corresponding to each audio file, such as the tag of the MP3 file is called ID3, the title, singing (playing) of the audio file can be stored in this tag Information such as author, composer (lyricist), lyrics, audio type, etc., the audio type includes rock, jazz, country, classical, etc. The output signals of different ty...
