Ebumeter provides level metering according to the EBU R-128 recommendation. The current release implements all features required by the EBU document.

For more detailed info on R-128 see the EBU site or the papers section of my website.

The upper bargraph shows either the Momentary or the Short term loudness as selected by the M and S buttons to the right. The two thinner ones below display the Loudness range (LRA) and the Integrated loudness (I) which are also shown in numerical form.

The +9 and +18 buttons switch between the two ranges required for an EBU-mode meter. The LU and FS buttons select either the relative scale in LU or the absolute one in LUFS.

The Stop, Start and Reset buttons control the Integrated loudness measurement.
