The present disclosure provides a volume adjusting method, a device, and a terminal device. In the method, audio information of an audio source may be obtained when a terminal device is playing the audio source. An audio amplitude corresponding to the audio information is determined basing on the audio information. The audio amplitude is adjusted according to an amplitude adjustment coefficient, and the amplitude adjustment coefficient is assigned according to the value of the audio amplitude.

The embodiment of the disclosure provides a volume adjusting method and device, a mobile terminal and a storage medium. The method includes: acquiring first audio information corresponding to an audio source when detecting that the audio source of a terminal device is playing; determining a first audio amplitude of the first audio information; determining a second audio amplitude of second audio information when the first audio amplitude meets a preset query condition, wherein the second audio information is played after the first audio information; determining corresponding adjustment information when the second audio amplitude meets a preset adjustment condition; and adjusting a volume of the terminal device according to the adjustment information. The disclosure improves the volume adjustment efficiency and reduces the energy consumption of the terminal device.
