We have just updated HoRNet ELM 128 MK2, the EBU loudness meter with loudness normalization.
HoRNet ELM 128 MK2 Version 2.1.0 – Advanced LUFS Metering and Real-Time Normalization
We are pleased to announce a major update to the HoRNet ELM 128 MK2, our powerful LUFS meter plugin built on the EBU R128 loudness standard. With the release of version 2.1.0, we’re introducing significant enhancements that improve both stability and functionality, reaffirming ELM 128 MK2 as a top-tier solution for loudness metering and normalization in professional environments.
Whether you’re working in broadcast, post-production, music mixing, or mastering, the HoRNet ELM 128 MK2 gives you the tools you need to measure and control perceived loudness with precision.
At its core, HoRNet ELM 128 MK2 is a LUFS (Loudness Units Full Scale) meter designed to give you real-time insights into your audio’s dynamic content. It provides all five essential loudness readings defined by the EBU R128 standard:
Momentary LUFS: Real-time loudness measured over 400 milliseconds
Short-term LUFS: Loudness over 3 seconds
Integrated LUFS: Full-program loudness
Loudness Range (LRA): Dynamic variability within a program
True Peak: Highest absolute signal level, accounting for inter-sample peaks
These measurements offer a clear view of your audio’s behavior, making it easier to deliver consistent loudness levels that meet broadcast regulations or streaming service requirements.
One of the most versatile aspects of ELM 128 MK2 is its compatibility with a wide range of audio configurations. It supports:
Mono
Stereo
5.1 surround
This flexibility ensures you can use the plugin across a variety of post-production and mixing workflows, whether you’re finalizing a TV show, working on a film score, or mastering a podcast.
A standout feature of ELM 128 MK2 is its history graph, which lets you monitor loudness changes over extended periods. The plugin can display up to 12 hours of loudness history, providing you with a comprehensive view of how your audio evolves over time.
This is especially useful for long-form content like broadcasts, podcasts, or live performances, where keeping consistent loudness is critical.
To streamline your workflow, HoRNet ELM 128 MK2 includes a highly effective loudness normalization function. This feature automatically adjusts gain in real time, based on your reference level, ensuring that your audio meets target LUFS values without manual intervention.
The normalization function is compatible with all loudness modes—momentary, short-term, and integrated—allowing you to tailor the behavior to your specific workflow. This is ideal for both creative and technical professionals who need quick, reliable, and accurate loudness adjustments.
The new Continuous Normalization Mode introduced in version 2.1.0 ensures the plugin constantly adapts the gain in response to the loudness reading being monitored, helping maintain consistent loudness throughout the program.
Unlike basic peak or RMS meters, LUFS incorporates a pre-emphasis filter that simulates the way the human ear perceives loudness. This means that the measurements provided by ELM 128 MK2 are not only technically accurate but also more aligned with how we actually experience audio.
Using LUFS as your metering standard helps avoid loudness discrepancies between different types of content and ensures a more consistent listening experience for end users.
The latest release is a feature-rich update that brings the following improvements:
Fixed crash in Logic Pro X: Enhanced stability for macOS users
Fixed GUI display issues: Eliminated random yellow line artifacts that occasionally appeared on the interface
Fixed window size behavior: The plugin now properly saves and restores window size between sessions
Added Continuous Normalization Mode: Automatically adapts gain continuously for smoother operation
Increased maximum gain adjustment: Now supports up to 30dB of gain, giving you more headroom for loudness correction
These updates not only resolve previous issues but also extend the functionality and precision of the plugin, making it more capable than ever before.
Version 2.1.0 is a free update for all current owners of HoRNet ELM 128 MK2. Simply log into your user area on the HoRNet website and download the latest version. With this update, we’ve made the plugin more robust, more intuitive, and even more aligned with professional metering standards.
If you’re producing content that needs to comply with broadcast, streaming, or platform-specific loudness guidelines, HoRNet ELM 128 MK2 gives you the tools to measure, adjust, and monitor loudness with total confidence. Its combination of visual clarity, real-time metering, and auto-normalization sets it apart from standard loudness meters.
It’s an ideal solution for:
Broadcast engineers needing to meet EBU R128 or ITU BS.1770 standards
Mastering engineers optimizing tracks for Spotify, YouTube, or Apple Music
Post-production houses working on multi-channel, long-form content
Podcast producers and content creators ensuring consistent playback volume
Whether you’re an existing user or just discovering HoRNet ELM 128 MK2, this update represents an important step forward in accurate, intelligent loudness metering. The plugin remains light on CPU, intuitive in design, and robust in functionality.
