What NUGEN ISL 2ST Is For
NUGEN ISL 2ST is designed to finalize your mixes with impeccable True Peak compliance. Whether you are mastering for streaming platforms, TV/cinema mixing, or podcast production, it ensures a controlled maximum level without downstream distortion or coloration. The DSP extension allows integration of the same transparent rendering in Pro Tools HDX chains with very low latency, both in studio and broadcast environments.
Main Features
Reference True Peak Limiter
Based on the standardized ITU-R BS.1770-4 algorithms, ISL 2ST guarantees strict adherence to the true peak level. The Apple "afclip" detection precisely manages inter-sample reconstructions to avoid hidden clipping during encoding or transcoding.
Transparent and Musical Protection
The TPlim control automatically adjusts the transfer curve for an invisible safety barrier, while the auto-release analyzes content, especially in the low frequencies, to prevent pumping and preserve attack and clarity.
Advanced Visual Analysis
Steering and ducking indicators help maintain directional integrity and ambiance. You quickly achieve the optimal setting for each program, from feature films to streaming music.
Ready for Streaming and Broadcast
ISL 2ST secures delivery to Apple Music, Spotify, Tidal, and broadcasters by preventing distortions introduced by codecs and maintaining high-resolution file quality. The limiting chain at the end of the mix remains transparent, even on content with strong low-frequency energy.

Questions frequently asked
Does the ISL 2ST work with Pro Tools HDX?
The included DSP plug-in supports the AAX DSP format for Pro Tools environments compatible with Avid HDX, delivering very low latency.
Which peak standard is used by this limiter?
The algorithm is based on the ITU-R BS.1770-4 recommendation. This reference allows control of inter-sample peaks during mix finalization.
How to avoid distortion after encoding for streaming?
Apple afclip detection manages inter-sample reconstructions. It limits clipping risks introduced during encoding or transcoding. Delivery to Spotify, Tidal, and Apple Music is thus secured.
What Mac or Windows configuration is required?
On Mac, the software requires OS X 10.9 and 1 GB of RAM. On Windows, it runs from Windows 7 with 1 GB of RAM.
Does the limiter preserve transients in the low frequencies?
The TPlim control automatically adjusts the transfer curve. The auto-release analyzes low-frequency content to reduce pumping and preserve the attack.
