Method for adjusting output volume and system thereof

Abstract

The invention discloses a method for adjusting output volume. The method comprises the following steps: when default output volume can not satisfy a media file output volume requirement, through detecting the output volume of the media file when playing the media file, determining time of carrying out output volume compensation adjustment; carrying out the compensation adjustment to realize self adjusting of the output volume. The invention also discloses a system for adjusting output volume. A determination unit in the system is used for determining time of carrying out output volume compensation adjustment through detecting media file output volume when playing the media file. A compensation adjustment unit in the system is used for realizing self adjusting of the output volume through carrying out the compensation adjustment. According to the method and the system of the present invention, self adjusting of the output volume is realized, and reduction of user experience feeling is avoided.

Description

technical field [0001] The invention relates to an output volume adjustment technology, in particular to a method and system for automatically adjusting the output volume of a media file when the media file is played. Background technique [0002] The playback of media files is very common in various multimedia applications. Due to the diversity of sources of media files, the volume of the media files used as the source files is usually inconsistent and fluctuates in a wide range, thus causing the user to pre-set an appropriate output volume for one of the media files , but when playing another media file, the output volume may be inappropriate. For example, the output volume is too low or too high when playing the media file. In this case, the output volume must be re-adjusted for different media files every time. Even sometimes the user has adjusted the output volume of the media file to the maximum, but still cannot obtain a suitable output volume. The solutions for ad...

AI Technical Summary

Problems solved by technology

The disadvantage of this solution is: since it only involves the adjustment of the output volume of the hardware, for media files whose output volume is originally very small, there is nothing that can be done if the hardware volume is adjusted to the maximum and cannot meet the requirements. Incomplete adjustment

The disadvantage of this solution is: although the link of adjusting the software output volume is added compared to the existing solution one, the automatic adjustment of the output volume cannot be realized. If the default output volume is not suitable, the user intervention and manual adjustment are also required.

The disadvantage of this solution is: although the automatic adjustment of the output volume can be realized, this automatic adjustment will cause the output volume change trend of the same media file to be inconsistent with the original output volume change trend of the media file, mainly because the output volume is adjusted at different times. The adjusted gain coefficients are inconsistent. For the same media file, for example, if the original output volume of the media file is relatively high in 1 second to 3 seconds, and exceeds the preset target output volume, the output volume will be automatically reduced; However, the original output volume of the media file in 3 seconds to 5 seconds is relatively small, and the output volume has not reached the preset target output volume, then the output volume will be automatically increased; The output volume of the media file is inconsistent with the original output volume change trend of the media file. The output volume is partially large or low, resulting in distortion, which makes the user subjectively feel that the output volume of the same media file is suddenly high or low, thus greatly reducing the user experience. sense of experience

[0010] To sum up, each of the above existing solutions has its own shortcomings. At present, there is an urgent need for a solution to adjust the output volume, which can take into account the automatic adjustment of the output volume and the user experience, and make a good balance between the two. In other words, it can not only realize the automatic adjustment of output volume, but also avoid the reduction of user experience
