NUGEN ISL 2 (from ISL 2 ST)｜Ultimate True Peak Limiter Upgrade

Born for Modern Streaming and Broadcast, The Last Line of Defense for Pristine Audio Quality

NUGEN ISL 2 is a **True Peak Limiter** specifically designed for modern audio production workflows. In today's digital audio world, whether it's music mastering, film and TV post-production, or broadcast engineering, compliance with international loudness standards is a fundamental requirement. Traditional peak limiters cannot handle inter-sample peaks generated by digital-to-analog conversion (D/A conversion) or lossy compression (e.g., MP3, AAC), which can lead to unexpected distortion and clipping. ISL 2 was created to solve this problem. It employs international standard algorithms like ITU-R B.S.1770, providing precise look-ahead processing, allowing you to easily achieve **loudness standard compliance** while focusing on your creative work, ensuring your audio sounds flawless on any playback system.

From Apple Music, Spotify to Netflix, the world's leading **streaming platforms** have strict true peak specifications for audio delivery. ISL 2 not only prevents distortion introduced by downstream codecs, but its unique TPlim control and Auto-release function also protect your audio dynamics with minimal coloration, maintaining sonic transparency and impact. Whether you are performing **mastering** or **broadcast post-production**, ISL 2 is an indispensable last line of quality defense in your workflow, ensuring your work is delivered to listeners in its most original and purest state.

Product Features

• Precise True Peak Limiting: Utilizes true peak algorithms compliant with multiple international standards such as ITU-R B.S.1770-4, EBU R128, ATSC A/85, and Apple 'afclip', ensuring 100% compliant audio delivery.
• Extremely Transparent Audio Quality: Intelligent look-ahead algorithm precisely predicts and suppresses true peaks without affecting audio dynamics and impact, avoiding coloration caused by traditional limiters.
• Built for the Streaming Era: Effectively prevents inter-sample peak distortion generated during encoding by lossy compression formats like MP3 and AAC, making it an essential tool for mastering for platforms such as Apple Music, Spotify, and Tidal.
• Dynamic Auto-release: Automatically monitors the low-frequency content of the input audio, dynamically adjusting the release time to effectively prevent distortion and maintain sound clarity, even when processing bass-rich music.
• Innovative Visualization Interface: Unique audio Steering and Ducking meters provide intuitive visual feedback, helping you quickly find optimal settings, making it easy to preserve surround sound directionality or ambient integrity.
