HoRNet ELM128 MK2 – EBU R128 compliant loudness meter with 5.1 support and realtime normalization

HoRNet ELM 128 MK2 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.

The five meters use different integration times and metering concepts:

  • Momentary: measures the loudness of the last 400ms
  • Short term: measures the 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.

The plugin supports mono, stereo and 5.1 surround metering with a handy history graph that you can use to see the loudness of your signals up to 12 hours earlier.
