Editing Dynamic range compression (section)

=== Marketing ===
Most television commercials are heavily compressed to achieve near-maximum perceived loudness while staying within permissible limits. This causes a problem that TV viewers often notice: when a station switches from minimally compressed program material to a heavily compressed commercial, the volume sometimes seems to increase dramatically. Peak loudness might be the same—meeting the letter of the law—but high compression puts much more of the audio in the commercial at close to the maximum allowable, making the commercial seem much louder.<ref>{{Cite web |url=https://www.pinsentmasons.com/out-law/news/tv-ads-sound-too-loud-and-rules-should-change-says-regulator |title=TV ads sound too loud and rules should change, says regulator |website=Out-Law News |publisher=Pinsent Masons |language=en-GB |access-date=2019-11-03}}</ref>
