After many years of complaints from the public about trailers and commercials sounding much louder than the actual programmes they fit around, broadcasters are tightening the rules
A programme sounds louder if its average level has been artificially increased by using too much compression, and there are sophisticated meters available to measure this. If you can't afford one for your mix, remember to be very careful with compression and only use very moderate amounts, if you want to avoid a technical fail!
