VisLM - The LUFS & Loudness Meter Plugin
VisLM is the go-to loudness meter plugin for professionals who demand accuracy. With real-time metering, detailed history, and customisable loudness parameters, VisLM gives you full control over your audio’s loudness compliance. The plugin measures loudness using LUFS (Loudness Units Full Scale) to give precise readings, making it the perfect LUF plugin for staying within international broadcast standards.
Enhanced transparency
ISL is an intelligent True Peak limiter that prevents distortion and ensures that your audio remains pristine, no matter how loud. This loudness plugin uses advanced algorithms to offer transparent and reliable limiting without compromising the dynamics of your sound.
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

For post and broadcast
VisLM is an ideal tool to achieve average loudness harmonisation from differing sources, consistently balancing music, dialog and special effects in order to hit specification easily and intuitively.
World class, broadcast quality limiting is an essential requirement for any broadcast production, and the latest standards also demand True Peak compliance. ISL delivers both, giving you superb sound with complete confidence when meeting True Peak delivery criteria.
LM-Correct is ideal for use in situations where time is of the essence, providing an automatic method of rapidly conforming audio to current loudness standards. The plug-in can be used within a project to measure and correct audio without needing to leave the editing environment, enabling rapid in-place loudness normalisation of mono, stereo or multi-channel audio.
