NUGEN ISL w DSP Extension

NUGEN ISL w DSP Extension｜Broadcast-Grade True Peak Limiter (with DSP Acceleration)

Industry Standard, Providing Ultimate Transparent True Peak Protection for Your Audio

In today's era of multi-platform audio distribution, meeting loudness standards and avoiding waveform clipping distortion has become fundamental to professional audio production. NUGEN ISL is a look-ahead True Peak Limiter specifically designed to solve this problem, allowing creators to focus on the art of sound while automatically handling complex technical compliance issues. Whether it's for mastering for Spotify, Apple Music, or producing broadcast-grade content that meets strict specifications like Netflix and EBU R128, ISL provides extremely transparent and reliable peak control, ensuring your work sounds flawless on any playback system. This version also includes Avid HDX DSP Extension, bringing powerful, near-zero latency processing performance to Pro Tools HDX users.

ISL employs the ITU-R B.S. 1770 standard algorithm to accurately predict and suppress inter-sample peaks generated by digital-to-analog conversion (DAC) or lossy compression (such as MP3, AAC), completely eliminating the risk of downstream distortion. Its exclusive TPlim control and intelligent auto-release function provide robust protection while maximizing the preservation of audio dynamics and clarity, making it an indispensable last line of defense in all professional workflows.

Product Features

• Global Broadcast Standard Compliance: Full support for ITU-R B.S. 1770 and related standards, including Apple's 'afclip' true peak detection algorithm, ensuring your work meets the delivery specifications of major global broadcast and streaming platforms.
• Netflix Official Certification: As a member of the Netflix Production Technology Alliance, ISL has undergone rigorous evaluation to ensure full compliance with Netflix's technical and workflow requirements, providing confidence for producing top-tier film and television content.
• Optimized for Streaming Platforms: Using ISL on the master bus effectively prevents inter-sample peak distortion caused by lossy compression codecs like MP3 and AAC, ensuring your music is presented in its most pristine form on platforms such as Apple Music, Spotify, and Tidal.
• Avid HDX DSP Acceleration: This version includes AAX DSP format, allowing computational load to be offloaded to Avid HDX hardware, achieving ultra-low latency processing performance, especially suitable for large, complex post-production and mixing projects.
• Intelligent Auto-release: The plugin continuously monitors the low-frequency content of the audio and dynamically adjusts the release time, effectively preventing unnatural pumping effects or distortion when processing bass-heavy material, maintaining sonic transparency.
• Exclusive TPlim Control: Unlike traditional limiters, ISL's TPlim control automatically adjusts conversion curve parameters to provide precise brickwall protection in the least intrusive way, achieving the set true peak limit.
• Innovative Visual Meters: Unique Audio Steering and Ducking meters provide clear visual feedback, helping you quickly assess the limiter's impact on stereo image and spatial feel, making it easy to find the ideal settings.
