EEEE loudness oscillations L R C LFE Ls Rs ALM 5 1 ALM 5 1 is key in your mixing workflow Based on the new ITU EBU and ATSC loudness standards the plugin offers you full Loudness and True Peak Metering for Mono Stereo and 5 1 channel for mats featuring measurements for Momentary Short Term and Integrated Loudness with Loud ness Range and Max True Peak Level It your target is 23 LUFS conform with EBU specification or is 24 LUFS conform with ATSC specification or even If you want to use the relative gate of 10 LU or not ALM 5 1 is all you need to control the loudness of your audio material Both LU and LUFS scales are available and you can set the start and the stop of your measurements or you can simply let the plugin do it by following the host transport It you prefer a higher resolution in the target zone you can use the 9 LU scale and if you pre fer a higher dynamic range you can use the 18 LU scale With both value and bar indicator for Loudness Range you can decide if your audio needs or not more dynamic compression The interface is very flexible you can use it in wide or narrow view In both cases you don t have to worry about the Peaks because there ALM 5 1 features peak holders and led indicators to let you know anytime a overload occurs Two scales with different reference levels 18 dBTP and 20 dBTP are available for the True Peak Meter Also ALM 5 1 takes into account all the inter samples
