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 8):
The audio enhancement method of  claim 7 , further comprising:\n adding the weighted mid signal and the input first channel signal to the weighted side signal by the mixing module; and adding the weighted mid signal to the input second channel signal to generate an added result and subtract the weighted side signal from the added result by the mixing module; wherein when the side-mid ratio minimum is larger, the first weighting value is smaller and the second weighting value is larger, and when the side-mid ratio minimum is smaller, the first weighting value is larger and the second weighting value is smaller.
