HoRNet Plug-Ins has released ELM128, a metering plugin that complies with the EBU R128 standard.
The plugin provides five different loudness measurement: momentary, short-term, integrated, dynamic range and true peak.
This new kind of loudness metering comes from broadcasting and aims to reduce the difference in the perceived levels of different programs, to help with this task HoRNet ELM also provide a normalization function that adjusts the gain in realtime so that no signal exceeds the suggested -23 LUFS.
This meter uses LUFS as measurement units (Loudness Units Full Scale) a LUFS is equivalent to a dB but the difference come from the pre emphasis filter used before any loudness calculation, this filter compensates the non linearities of the human hear do that any measurement takes into account ho we human perceive sounds.
