Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] Please refer to figure 1 , which shows a method flowchart of a volume adjustment method provided by an embodiment of the present invention. The method, including:
[0029] Step 102, obtaining the expected actual auditory loudness;
[0030] Step 104, calculating the absolute auditory loudness of the multimedia data during playback through the auditory equal loudness curve;
[0031] Step 106, calculating the volume gain ratio according to the expected actual auditory loudness and the absolute auditory loudness;
[0032] Step 108, adjusting the playing volume of the multimedia data according to the volume gain ratio.
[0033] In summary, the volume adjustment method provided by this embodiment obtains the expected actual audito...

The invention discloses a method and a device for adjusting volume, belonging to the field of audio and video processing. The method comprises the steps of acquiring expected practical hearing loudness; calculating absolute hearing loudness of multimedia data in playing according to a hearing equal-loudness curve; calculating volume gain proportion according to the expected practical hearing loudness and absolute hearing loudness; and adjusting playing volume of the multimedia data according to the volume gain proportion. According to the method, the expected practical hearing loudness is acquired, the absolute hearing loudness of the multimedia data in playing is calculated according to the hearing equal-loudness curve, the volume gain proportion is calculated according to the expected practical hearing loudness and absolute hearing loudness, and the playing volume of the multimedia data is adjusted according to the volume gain proportion. Through adoption of the method, a user does not need to adjust the volume by hands according to practical hearing sense, the same electronic equipment prevents unstable volume, and the volume adjustment manner is simplified.
Description
technical field [0001] The invention relates to the field of audio and video processing, in particular to a volume adjustment method and device. Background technique [0002] Volume control is an essential function of all electronic devices that support multimedia playback. [0003] Currently, the volume control method most commonly used in electronic equipment is digital volume control. The digital volume control sets multiple candidate volume values, and each volume value corresponds to a different volume gain. When the electronic device plays a piece of multimedia data, the actual volume of the electronic device=the original volume of the multimedia data*the volume gain corresponding to the volume value. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] Since the digital volume controls on different electronic devices adopt different volume gains, users can only manua...
