HoRNet ELM 128 is 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.

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.
