The NUGEN Modern Mastering Bundle is three plugins for finishing tracks with confidence: MasterCheck to hear how streaming services will treat your master, ISL st for transparent True Peak limiting, and Visualizer for full audio analysis. It's aimed at producers who master their own music for streaming release.

MasterCheck
Audition loudness normalisation and codec processing for Spotify, Apple Music, YouTube and more, with Integrated loudness, PLR, PSR and True Peak metering. It shows you whether extra loudness is actually buying you anything once the platform turns it down.
ISL st
A look-ahead True Peak limiter to ITU-R BS.1770, with a TPlim control that sets the ceiling and handles the rest as transparently as possible. Your master stays clean after MP3 and AAC encoding.
Visualizer
Spectrum, spectrogram, vectorscope, correlation and level views in one resizable window, for catching problems your room or headphones might hide.
Why the three together
Check, protect, analyse: it's a tidy end-of-chain toolkit that sits after whatever EQ, compression and limiting you already like, and makes sure the result survives the trip to the listener.
