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).

BUTE Loudness Analyser 2 is a loudness meter plugin designed as an aid for mixing and mastering to loudness standards and to avoid unwanted distortion downstream.

It's packed with smart workflow features for a smooth user experience including built-in presets for all major streaming and broadcasting platforms, and our proprietary algorithms provide accurate and reliable analysis.

What Does Bute Do?

Many producers are moving towards mixing and mastering within loudness specifications set by major streaming and broadcasting platforms for quality assurance.

Loudness indicates the perceived level of a signal that is indicative of human hearing, making BUTE Loudness Analyser 2 a useful reference tool when mixing or mastering.

Signum's proprietary algorithm provides accurate loudness metering data on a beautiful and completely interactive graphical user interface which clearly highlights areas requiring your attention helping you optimise the quality of mixes and masters, while avoiding potential delivery rejections or undesireable distortions downstream.

Smart, Synchronized Workflow for Broadcasting, Post and Games

Loudness metering tools are ideal for balancing music, dialog, and sound effects whether in stereo or up to Atmos 7.1.2 surround sound.

Long-form content is made much easier to deal with using our smart history overview.

Get an overview of up to 10 hours of content and navigate to any section of a track with ease.

BUTE's custom alert system will clearly point out areas that go out with a user-specified range and any True Peak overshoots.

A wide array of industry-standard presets are included.

Mixing and Mastering with Bute

BUTE plugins are compatible with VST, AU, and AAX (including Audio Suite), so will synchronize harmoniously with almost any DAW.

The smart auto re-metering feature gives instantaneous feedback on how loudness will be affected by changes to the mix so there is no need to re-meter the whole mix.

Readings for Absolute/Relative Scale, True Peak/LUFS, and Max/Live modes are easy to toggle between from the main display.

Compact Read-Out View

When screen estate and CPU are at a premium, a compact read-out helps keep things optimized.

BUTE is completely resizable and scalable.

Even while in compact view, you can easily switch between display settings and obtain read-outs while saving screen estate for other programs.

Bring Your Music to All Streaming Platforms

All the tools in your hand to make your music sound optimal on Spotify, YouTube, TIDAL, Apple Check, and more.

Signum regularly updates the presets and include most platforms.

User-defined presets for internal standards can also be created and saved
