The Basics

iLok is a copy protection method used by many of our brands.

It has 3 types of activations, iLok USB, iLok Machine, and iLok Cloud.

Different brands/products will offer different iLok methods. iLok USB is always an option, but the availability of iLok Cloud and iLok Machine methods is at the discretion of the software developer.

iLok Account

For all iLok protected products, you will need an iLok account. You can create one for free here: ilok.com/#!registration

iLok License Manager

To manage your iLok licenses, there is a dedicated app called iLok License Manager. This app is used to register, activate, and move your licenses between locations.

You can download the latest installers from the iLok website: ilok.com/#!home

iLok USB Key

iLok USB

This activation is stored on an iLok 2 or 3 USB key.

It is the best option for portability, if you frequently move between multiple machines, and offline use.

iLok Machine ID

Machine ID

This activation is stored locally on your computer.

While this is a convenient way to work offline, and does not require the additional cost of an iLok USB, there is the risk of a license being lost in the case of a drive failure.

This option also requires extra care when you upgrade to a new computer, the license(s) must be deactivated on your old machine first to ensure you do not lose them.

iLok Cloud

iLok Cloud

This activation is based online, and requires a "cloud session" using the iLok License Manager.

It requires an active internet connection for the entire time you use the plugin(s).

ISL 2st - Mono and Stereo Limiter

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 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.

Pristine quality

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

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 visualizations

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.

For Post-Production

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.

Trasparent, Reliable

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.
