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.
"We use NUGEN Audio tools in every mix session across the board. They are fantastic to use and completely do the job."
Daniel Jones | Vaudeville Post
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
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."
David Hough | Audio Director | Austin City Limits
"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"
Erinn E. Thorp | Senior Production Engineer | Turner Studios
"LM-Correct offers us a quick and easy way to ensure compliance without changing the original dynamic range or needlessly duplicating media. It's also a great time-saver to have analysis and correction in a single window rather than having to alternate between systems."
