Caution: “Treat Mono As Dual Mono” Will Reduce LUFS By 3dB

In this video I show you how checking the option, “Treat Mono As Dual Mono” when setting LUFS levels in Audacity will actually reduce your exported file’s level by 3dB. This option is there to meet the EBU’s broadcast standard for LUFS when working with a dual-mono track. A dual-mono track is a track with left and right channels (similar to a true stereo track) but unlike a stereo track, the audio in each channel is identical. But when used on a mono track, this option reduces the LUFS level by 3dB. As I show you in this video, if you’re exporting a mono podcast at -19dB LUFS with this option checked, you’re actually exporting at -22dB LUFS. This is important information.
