Abstract

The provided sound volume management method comprises: receiving control signal for outputting audio signal; obtaining current time and its time interval; reading the set gain in table or using regulated gain to amplify the audio signal; obtaining regulated gain to calculate a comprehensive gain value according to the regulated one and original value to update the gain in table. This invention avoids unnecessary manual operation.

Description

【Technical field】 [0001] The present invention relates to a volume management system and method, in particular to a system and method for automatically adjusting the volume according to the time period to which the current time belongs. 【Background technique】 [0002] In modern society, people's pace of work and life is accelerating day by day, which increases stress and irritability. In order to relieve stress and relieve irritability, people often enjoy music when they are working, driving or taking a nap. Music has become an indispensable companion for people.
