Nugen Audio ISL 2
True-Peak Limiter Plugin with Surround Support up to 7.1.2
Mastering & Post-production
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.
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.
- Broadcast compliant
- Protect AAC, MP3 etc.
- Master for online delivery
- Surround capable
- ITU-R B.S. 1770-4
- Apple Afclip
- Auto release
- TPmax limit
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 ambience, 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 down-stream 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.
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.
In use on a daily basis in thousands of studios across the world, ISL is a proven reliable standard for transparent True Peak limiting.
Now in version 2, ISL delivers reliable brick wall limiting and in-depth control to handle the most demanding of situations.
