Getting Loudness under control | | Loudness differences between programs and stations are a well known issue. Not only is the problem found during programs - the issue of loud commercials, where volume levels jump during commercial breaks is a common complaint amongst digital television viewers and can even drive them away from a channel.This issue will continue to demand attention - as viewers continue to demand the best possible viewing experience.
