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 2 offers surround compatibility up to 7.1.2 for Post and Movie production.
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.
Powerful processing – 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.
Innovative visualisations – 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.
