Nugen Audio ISL is a transparent look-ahead limiter specifically engineered to effortlessly handle True Peak compliance, freeing you up to focus on unleashing your creativity in audio production.
ISL uses the standardized 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.
Note: There are 2 versions of ISL (Surround and Stereo)
ISL is a transparent True Peak surround limiter with precise look-ahead intelligence, allowing you to focus on creative audio production while it takes care of compliance for you.
ISLst is a transparent True Peak stereo limiter with precise look-ahead intelligence, allowing you to focus on creative audio production while it takes care of compliance for you.

No need to second guess your sample-peak limiter time and again, or deliberately increase headroom to avoid a downstream problem. Just dial in your True Peak limit and let ISL take care of the rest.

ITU-R B.S. 1770-4
Unlike traditional limiters, ISL provides a TPlim control, automatically adjusting transfer curve parameters for minimally invasive brick-wall protection.
Auto-release monitors incoming audio for low-frequency content, dynamically adapting to prevent distortions and deliver transparent audio in the most demanding of situations.
With unique steering and ducking meters, ISL guides you to the perfect settings. Whether you are preserving directional integrity or atmospheric ambiance, ISL gives you the information and control you need to achieve your objective with ease. New processing enhancements assess the incoming audio for frequency content and automatically take care of those minor adjustments required when LF content drives the limiter, delivering increased transparency whilst maintaining our renowned reputation of intuitive operation.
For music production
Let ISL take care of your mastering for today’s music delivery services (Apple Music, Spotify, Tidal, etc.) The risk of distortion from downstream codec conversion (mp3, AAC, etc.) is eliminated with ISL on the master bus.
Mix and master with confidence that your audio will be delivered the way you intend, without downstream distortions introduced by inter-sample clip reconstruction errors.
For post and broadcast
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.
With ITU-R B.S. 1170-4 compliance and a dedicated brick-wall TPlim setting, you can produce with confidence, leaving ISL to transparently take care of the compliance.
Loudness Toolkit has been included in the audio tool category of Netflix’s Production Technology Alliance. This is a program for manufacturers that handles sound, image, or metadata during the processes of production to postproduction.
