Essential Information About NUGEN ISL Software with DSP Extension
- Transparent True Peak limiter compliant with ITU-R BS.1770-4, featuring Apple "afclip" detection to control inter-sample peaks.
- Avid HDX integration via AAX DSP: broadcast-quality brick-wall protection with minimal latency in Pro Tools.
- Intelligent "TPlim" controls and adaptive auto-release for smooth, musical, and non-invasive limiting.
- Advanced visualizations (steering/ducking) to preserve stereo/surround image and prevent codec artifacts (AAC, MP3, etc.).
What NUGEN ISL Is For
NUGEN ISL is a look-ahead limiter dedicated to true peak compliance for music mastering, post-production, and broadcast. It secures your mixes before encoding and streaming platforms, eliminates distortions related to inter-sample reconstruction, and ensures compliant delivery while preserving dynamics and spatialization.
Main Features
Trusted True Peak
Based on the standardized ITU-R BS.1770-4 algorithms, ISL supports Apple "afclip" detection to spot inter-sample overs. The "TPmax" setting ensures a strict ceiling to meet broadcast and streaming specifications.
Accelerated HDX Workflow
The DSP Extension adds AAX DSP execution within Pro Tools | HDX for a consistent limiting chain across recording, editing, and finishing, with very low latency and stability suited for broadcast deliverables.
Transparency and Control
The TPlim control automatically adjusts the transfer curve, while the auto-release analyzes content, especially low frequencies, to avoid pumping and maintain clarity. Steering/ducking meters guide adjustments to preserve directional integrity and ambiance.
Designed for Broadcast and Streaming
ISL protects your masters from compression artifacts (AAC, MP3) and facilitates loudness compliance. It integrates into professional workflows where quality and compliance are essential; NUGEN's Loudness Toolkit suite, of which ISL is a cornerstone, is recognized in the high-end production ecosystem.
