HoRNet ELM 128 is a metering plugin that complies with the EBU R128 standard. The plugin provides five different loudness measurements: momentary, short-term, integrated, dynamic range and true peak.
A spokesperson had this to say, "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."
The five meters use different integration times and metering concepts:
Momentary: measures the perceived loudness of the last 400ms
Short term: measures the perceived loudness of the last 3s
Integrated: it's the recorded loudness since the beginning of the measurement (or from the last reset operation) but discarding the longest silence parts or the highest passages that may occur in a long program (a movie, a tv show, etc.)
Range: is the loudness range of the program in LU
True Peak: this meter shows the maximum level of the signal in dBFS using a 4x oversampling (below 192KHz sampling frequency) to faithfully represent the inter-sample peaks
