First Sneak Preview Of ISL2 True Peak Limiter From Nugen Audio

Recently Nugen Audio announced the Loudness Toolkit 2 and at BVE we were able to take a sneak peak at LM-Correct 2. Now in this video Mike Thornton takes a first look at the new version of Nugen Audio’s unreleased True Peak Limiter ISL2.

With the new loudness workflows it is essential that we use true peak limiting to make sure we don’t hit digital headroom as we are often working less than a couple of dBs from digital headroom. Watch this video and find out about the new features that will be in ISL2 when it is released.

If you want to know more about true peak limiting, why it is so important and how to use the Nugen Audio ISL intersample peak limiter then you can watch two videos I made for Nugen Audio.

Auto Release Hold Mode

There is a new Intelligent Dynamic Release Mode to enhance algorithm transparency by automatically adjusting to program content in real time. The Auto button when enabled allows ISL2 to analyse the incoming audio signal for low frequency content and automatically extend the ‘hold’ time of the limiter to ensure a full wavelength passes before the release cycle is activated. This allows the use of shorter release times than might usually be employed, whilst ensuring that harmonic distortion is not introduced when low-frequencies trigger gain reduction.

Scrolling History View

There is a new section in centre of the plug-in which is accessed by this small H icon. This History mode when active, shows an alternative view showing the gain reduction history displaying the maximum reduction on all the channels going through the plug-in.

Steering and Ducking meters

Steering is a by-product of the action of limiting a stereo or surround signal when you don’t fully link each of the channel limiters whilst Ducking is the inverse effect of steering where other channels are ducked due to high level audio on one channel.

Independent Centre Channel Linking

When ISL2 is used in 5.1 or 7.1 mode, an additional Centre Channel control is available. This control allows independent linking of the Centre channel. 

Compact Mode

Although the ISL and now ISL2 have been designed to use at little screen real estate as possible, sometimes with a lot of plug-ins in use it would be nice to have a more compact mode and in ISL2 Nugen Audio have added a Compact view.

Vis-LM2

We hope to bring you a sneak peak of Vis-LM2 when it is closer to being finished, the final component in Nugen audio’s Loudness Toolkit 2.
