DSP version includes VisLM DSP & ISL DSP.

Precise, efficient, trusted

Loudness Toolkit is the leading solution for loudness compliant delivery. Everything you need to produce reliable, loudness-normalised audio, seamlessly integrated into your audio production workflow, from stereo up to 7.1.2-channel surround.

Mix towards compliance without breaking the creative flow, listen to True Peak audio ‘in-place’, and achieve faster than real-time quick-check-and-fix processing.

Breathtaking speed

Using an industry standard gives you confidence and peace of mind. VisLM delivers everything you need – intuitively, accurately and immediately. With a unique design focused on primary loudness parameters, VisLM combines an instant overview with detailed historical information, enabling you to hit your target first time, every time. Additional loudness logging and time-code functions allow for proof of compliance reporting and postmortem analysis with frame accurate referencing. VisLM is also the first software meter to measure dialog-gated LRA.

Enhanced transparency

ISL is a transparent look-ahead limiter designed to allow you to get on with creative audio production while it takes care of True Peak compliance for you.

ISL uses the standardised True Peak algorithms of ITU-R B.S. 1770 and related standards (including Apple ‘afclip’ True Peak detection), and is suitable for the control of audio for post production, music mastering and broadcast applications. True Peak limiting can also be used to ensure that downstream codecs (mp3, AAC etc.) do not introduce distortion into the signal.

Ultimate peace of mind

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.

Either within your NLE/DAW or as a standalone 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.
