About Audio Sharpen
When a recording sounds muffled or muddy, it can be hard to make out the details. Audio Sharpen works to clarify dull audio, bringing out definition so muffled voices and instruments become easier to hear. It's a useful rescue for recordings that came out softer or less crisp than you hoped.
