ISL 2 True Peak Limiter by NUGEN Review
ISL 2 is on the review table today, NUGEN tools are used by professionals in countless studios and production houses. As there are many professional limiters to select from when you deliver the final mix. I did use ISL 2 in the past two months to learn more about its features and to prepare this review.
I can tell you early that there is not a clear winner and that you would need more than one limiter to work in the professional space as you want to be able to select the result that sounds best to your customers. ISL 2 is one of the tools you need to have in your toolbox. NUGEN did send a review copy with no strings attached.
The plugins work as AAX, VST, VST3, AU, and AudioSuite. The AAX DSP version supports 7.1 audio up to 48Khz and 4 channels at 96kHz.
ISL 2 is an essential investment if you are a mixing or mastering engineer, you need another limiter besides it to have options available, I would recommend a combination of FabFilter’s Pro L2 and ISL 2 by NUGEN.
NUGEN’s ISL2 is an inter-sample true peak Limiter and a follows many of the ITU. The sound quality of ISL2 is honest. One of the key features of this tool is its transparent look-ahead limiting. With features like it prevents further distortion that could be introduced by compression and audio codecs.
ISL 2 should be used as final limiter just before tools like MasterCheck Pro, the tool also works as a broadcast limiter. The limiter works for scores ranging from mono through 7.1 surrounds mixes. It is compatible with ITU-R BS. 1770.
User interface & Usability
When it comes to presets NUGEN did include the ones to cover all the standard industry ones you need to deliver against for the different platforms, broadcast, and even the good old DVD mastering.
The UI has the NUGEN standard professional look and feels that is geared towards results. There is also a small UI available to reduce the real estate used by the plugin.
Rating: Five out of five stars
ISL 2 True Peak Limiter by NUGEN is a look-ahead brick-wall limiter that helps you to prepare your mono, stereo and surround mixes for various streaming platforms or when you deliver scores to picture. Even in the YouTube days you need and should add a limiter at the end of your chain before you load up a new video to Google’s sharing platform.
ISL 2 sits as the final limiter on a master bus it is perfect for broadcast and post-production. Combine this limiter with tools like MasterCheck Pro and you are ready to enter and compete in the loudness wars.
