Claim 1:
2. The method as described in claim 1, wherein the step of determining the audio signal gain difference between the current volume level and the baseline volume level according to the current volume level and a preset baseline volume level, includes steps of:
using the preset gain table to query, obtaining the gain value of the audio signal corresponding to the current volume level, according to the current volume level;
using the preset gain table to query and obtaining the gain value of the audio signal corresponding to the baseline volume level according to the preset baseline volume level;
carrying out difference calculation through the gain value of the audio signal corresponding to the baseline volume level, the gain value of the audio signal corresponding to the current volume level, obtaining the audio signal gain difference between the current volume level and the baseline volume level.
