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 10):
The audio enhancement method of  claim 7 , further comprising:\n filtering the input first channel signal to generate a filtered input first channel signal by a first band pass filter; delaying the input first channel signal and further subtracting the filtered input first channel signal from the delayed input first channel signal to generate a first residue signal by a first band rejection filter; filtering the input second channel signal to generate a filtered input second channel signal by a second band pass filter; delaying the input second channel signal and further subtracting the filtered input second channel signal from the delayed input second channel signal to generate a second residue signal by a second band rejection filter; weighting the filtered input first channel signal and the filtered input second channel signal according to the first weighting value and the second weighting value respectively and further adding the first residue signal and the second residue signal to the weighted filtered input first channel signal and the weighted filtered input second channel signal respectively to generate the enhanced first channel signal and the enhanced second channel signal by the mixing module.
