24/7 Logging
As a standard feature LM2 comes with hindsight: the radar can show the past 24 hours, but LM2 actually includes so much
memory of its own that you can take a detailed look one week back in time, even if it has had no connection to a computer.
Dump log files routinely to PC or Mac, import files into Excel or Numbers and create line charts for better overview.
Ingest Normalization
The primary application for LM2 is as a loudness meter but it does one more thing very well: automatic level offset of
programs at a no-compromise resolution (synchronous, 48 bit, fixed point engine). LM2 therefore includes a precision
true-peak limiter to avoid output overload when positive gain normalization is required. For fans of speech normalization,
allow LM2 to measure some regular dialog and normalize to that. Otherwise, let its relative gate function automatically take
care of all sources. Presets are included, so the choice is yours…
Production Applications
In production, program duration and sliding window descriptors are indispensable tools for attaining a specific target.
When connected to PC or Mac, LM2 further provides access to TC’s unique radar display visualizing loudness history and
the loudness range to stay within. The radar color codes show loudness developments so it’s easy even for a person not
specialized in audio to identify target loudness (green), below the noisefloor (blue), and loud events (yellow), colors also
used to show these properties in Fig 1, and in numerous technical TC papers.
