What NUGEN ISL 2 Is Used For
ISL 2 is designed to cleanly cap "inter-sample" peaks and ensure True Peak compliance across all types of programs: music, podcasts, video, cinema, and broadcast. Positioned at the end of the chain, it prevents codec-related distortions (MP3, AAC, etc.) and delivers masters optimized for streaming services while preserving dynamic integrity and spatialization.
Main Features
Standardized True Peak Limiting
Based on the True Peak algorithms from the ITU-R BS.1770 recommendation (including Apple "afclip" detection), ISL 2 provides compliant and reliable limiting for music, post-production, and broadcast. A dedicated "TPmax" mode facilitates meeting delivery criteria.
Intelligent and Transparent Protection
The TPlim control automatically adjusts the transfer curve for minimal yet effective protection. The Auto Release follows the content in real time, adapts to low frequencies, and avoids artifacts even in demanding situations.
Metrics That Guide Your Settings
The steering and ducking indicators offer clear insight into the limiter's action. ISL 2 analyzes the incoming spectral content and applies micro-adjustments to enhance transparency without sacrificing ease of use.
Optimized for Streaming and Broadcast
Manage your levels confidently for Apple Music, Spotify, Tidal, and broadcast without fear of inter-sample reconstruction errors. ISL 2 protects your masters from transcoding distortions and ensures faithful translation across all platforms.

Questions frequently asked
Does Nugen Audio ISL 2 protect masters intended for streaming?
The limiting is based on the ITU-R BS.1770 recommendation and controls inter-sample peaks. Distortions related to MP3 or AAC transcoding are thus prevented for deliveries to Spotify, Apple Music, or Tidal.
What is the difference between ISL 2st and ISL 2 for surround?
The ISL 2st edition supports mono and stereo formats. The ISL 2 edition handles surround up to 7.1.4 for post-production and cinema work.
Does the limiter preserve low frequencies without artifacts?
The Auto Release follows the content in real time and adapts to low frequencies. The TPlim setting automatically adjusts the transfer curve to limit with minimal action.
Is ISL 2 compatible with Mac and Windows?
The software runs on macOS 10.9 or later, as well as on Windows 7 or later. A minimum of 1 GB of RAM is required.
Is there a version compatible with Avid HDX?
ISL 2st DSP and ISL 2 DSP editions are compatible with Avid HDX. In DSP version, surround is supported up to 7.1.2, not 7.1.4. Steering and ducking indicators allow visualization of the limiting action.
