Audio Enhancement Techniques for Professional Videos

Capture quality first

Editing software can improve many problems, but it cannot recreate information that was never recorded clearly. Suitable microphones, sensible placement and a clean feed from a sound desk can make an enormous difference.

Noise reduction

Background hum, hiss and other steady noise can sometimes be reduced, although aggressive processing can make voices sound unnatural. The best result usually comes from careful, moderate settings.

Equalisation and compression

Equalisation can help speech sound clearer by balancing frequencies, while compression can reduce large differences between quiet and loud moments. Used together, they can make a soundtrack easier to listen to.

Balance the whole mix

Dialogue, music, ambience and effects should support one another rather than compete. Final level checks are important before delivery.
