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 1):
An audio enhancement device, comprising:\n an audio-calculating module configured to calculate 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 respectively; a ratio-calculating module configured to calculate a side-mid ratio of the side signal relative to the mid signal; a minimum-tracking module configured to track a side-mid ratio minimum within a certain time period; a weighting-calculating module configured to determine a first weighting value and a second weighting value according to the side-mid ratio minimum; and a mixing module configured to weight the mid signal and the side signal based on the first weighting value and the second weighting value respectively and adjust 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.
