LM-Correct gives you a unique, immediate and hassle-free route to loudness-compliant audio in your day-to-day loudness workflow, saving you time and preventing costly mistakes.
"I count on NUGEN Audio's VisLM visual loudness meter and LM-Correct loudness analysis and correction tool to ensure we're CALM-compliant. Since I started using VisLM and LM-Correct, PBS has not rejected or returned any of the programs I've delivered"
David Hough | Austin City Limits
Either within your NLE/DAW or as a stand-alone application, LM-Correct delivers automated compliance with True-Peak correction, solving your compliance issues on the spot. Used in conjunction with a real-time meter, LM-Correct saves iterative adjustments to the mix as you approach target levels, allowing transparent in-edit 'quick-touch' finishing of your audio. It’s an essential part of your loudness toolkit.
Automated, faster than real-time
For file based-processes (either with the standalone, Avid AudioSuite or Adobe Premiere Pro CC CEP version), LM-Correct rapidly assesses and adjusts the entire file much faster than real time. Automatically handling audio files from mono through 5.1, LM-Correct is compliant with all current loudness standards and if you need it you can specify the optional dialog-gated measure.
Automatically re-purpose and re-version
LM-Correct dramatically increases efficiency when delivering multiple versions and re-purposing for different regions and play-out specifications. Transform audio from one specification to the next with a single click, faster than real-time, without the need to manually re-purpose time and again in the editor.
Peace of mind
Our unique look-ahead true-peak limiter also prevents potential compliance failure due to loudness correction. With True-peak, Integrated Program and Short-term Maximum targeting you can be sure your audio is compliant every time. LM-Correct: total control and complete peace of mind in production.
Optional DynApt Extension - Powerful dynamics processing with a single click
Some of our global broadcast customers
Armand Klenk | Head Instructor Audio | SAE Institute
"We have been using VisLM and LM-Correct software plug-ins for about a year now, and they have become a critical part of our offering. We could not teach students about broadcast-related loudness without them."
Mike Felton | 'Later... with Jools' BBC TV
"I have been using VisLM and LM-Correct, along with NUGEN Audio's ISL real-time true-peak limiter, for almost two years and can say without hesitation that they are critical elements in my audio mixing workflow for the Jools show."
Steven Fox | Senior Broadcast Engineer | Southern Cross Austereo
"Since we've been using LM-Correct, we've seen a significant increase in our ability to meet OP-59 targets. With other products we've tested, we hit the mark only about 80 percent of the time. But with LM-Correct, our mixes hold up to scrutiny every time."
