Requirements According to License Type
For an EDU license, proof of eligibility (student/teacher ID) is required. UPG (upgrade) licenses require proof of a previous version of Loudness Toolkit or an eligible product. For CG (crossgrade), a serial number from a compatible competing software is requested. Check your eligibility before purchase to activate the license without delay.
What NUGEN Loudness Toolkit Is For
Designed for post-production, broadcast, streaming, podcasting, and mastering, Loudness Toolkit allows you to normalize level, control True Peak, and document compliance according to current standards. It harmonizes music, dialogue, and effects, prevents codec artifacts downstream, and secures your multi-platform deliveries.
Main Features
Accurate and actionable loudness measurement
VisLM provides an instant view of essential parameters (integrated, short-term, momentary, LRA) with detailed history, timecode marking, and log generation for compliance proof. The dialogue-gated LRA measurement helps target intelligibility without restricting useful dynamics.
Transparent True Peak limiting
ISL applies a look-ahead limiting compliant with ITU-R BS.1770 (including Apple "afclip" detection) to reach the required peak level while preserving tonal character and limiting codec-induced distortion (AAC, MP3, etc.).
Instant correction and dynamic adaptation
LM-Correct automatically corrects loudness and True Peak as a plug-in or standalone application. The DynApt extension adapts dynamics and LRA while preserving dialogue intelligibility and dramatic transitions, ideal for quick multi-spec variations.
Designed for production efficiency
Whether final checking, podcast normalization, or live control, the suite enables fewer iterations, faster decisions, and confident deliveries, with clear compliance tracking for your clients and broadcasters.
