Abstract:
An audio enhancement device including an audio-calculating module, a ratio-calculating module, a minimum-tracking module, a weighting-calculating module and a mixing module is provided. The audio-calculating module calculates a mid signal and a side signal according to a sum and a difference of an input first channel signal and an input second channel signal. The ratio-calculating module calculates a side-mid ratio of the side signal relative to the mid signal. The minimum-tracking module tracks a side-mid ratio minimum. The weighting-generating module determines a first and a second weighting values according to the side-mid ratio minimum. The mixing module weights the mid signal and the side signal based on the first and the second weighting values respectively and adjusts the input first channel signal and the input second channel signal accordingly to generate an enhanced first channel signal and an enhanced second channel signal.

Claim (Index 12):
The audio enhancement method of  claim 7 , further comprising:\n tracking a mid signal minimum within the certain time period by a mid signal minimum-tracking module; calculating a mid ratio of the mid signal relative to the mid signal minimum by a mid ratio calculating module; and determining the first weighting value and the second weighting value according to the side-mid ratio minimum and the mid ratio by the weighting-calculating module.
