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 4):
The audio enhancement device of  claim 1 , further comprising:\n a first band pass filter configured to filter the input first channel signal to generate a filtered input first channel signal; a first band rejection filter configured to delay the input first channel signal and further subtract the filtered input first channel signal from the delayed input first channel signal to generate a first residue signal; a second band pass filter configured to filter the input second channel signal to generate a filtered input second channel signal; a second band rejection filter configured to delay the input second channel signal and further subtract the filtered input second channel signal from the delayed input second channel signal to generate a second residue signal; wherein the mixing module weights 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 adds 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.
