NuGen Audio ISL Bundle v2.1.7 WiN&OSX
 

Genuine Brick-wall limiting, compliant with all current loudness standards. Finally, there is no need to second guess your sample-peak limiter time and time again, or deliberately increase headroom to avoid a downstream problem. Now you can simply dial in your True-peak limit and let ISL take care of the rest. 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.
