NUGEN MasterCheck v2 – Hear Your Master the Way Spotify Will Play It

Here is the modern mastering problem: you deliver one master, and every platform then re-processes it differently. Spotify turns it down one way, Apple Music another, YouTube a third — and a master that sounded perfect in your studio comes back quieter, duller or distorted by codec artefacts you never heard. NUGEN Audio MasterCheck v2 exists to end that surprise, by letting you preview exactly what each platform will do before you submit. It is $39.99.

Every Target, One Interface

MasterCheck v2 ships with pre-configured presets for Spotify, Apple Music, YouTube, Netflix, Tidal, Amazon Music and broadcast standards. Metering covers integrated loudness, short-term and momentary loudness and true peak, to EBU R128 and ATSC A/85 specifications. The dynamic range display shows loudness range and dynamic density, so you can see whether your master is genuinely dynamic or just loud. A/B reference comparison against a loudness-matched track keeps your judgements objective — no more chasing a reference that is simply playing back hotter.

Codec Auditioning: The Feature That Pays for Itself

Encoding changes sound. MasterCheck’s codec auditioning routes your audio through MP3 and AAC simulations so encoding artefacts — the swirl on cymbals, the smear on transients — are audible at the mastering stage, while you can still fix them. The true peak limiting preview shows how your master behaves after platform normalisation and limiting, and the headphone translation check simulates typical consumer headphone responses, because most of your audience will never hear your studio monitors. Together these previews turn delivery from a lottery into a checklist.

Who Needs It

Mastering engineers delivering to multiple platforms use it as the final quality gate. Self-mastering producers get professional compliance without a professional’s decade of trial and error. Post-production engineers working to broadcast loudness standards get exact metering in the session. Podcast producers — held to their own platform loudness requirements — use the same tools to keep episodes consistent. If audio leaves your studio and lands on a service with rules, this is how you verify it before it does.

Mac-Native and Session-Friendly

This is the Mac build, running natively on macOS 10.13+ in VST3, AU and AAX formats for Logic Pro X, Pro Tools, Ableton Live, Nuendo, Cubase and other professional hosts. The interface presents all critical loudness metrics simultaneously and clearly, designed for engineers who read meters the way drivers read dashboards — at a glance, without breaking concentration on the music.

The Delivery Checklist, Formalised

Professional delivery runs on routine, and MasterCheck turns the routine into a visible checklist: integrated loudness against the platform preset, true peak with headroom for encoding, loudness range appropriate to the genre, codec audition clean, headphone translation checked, reference compared at matched level. Podcasters apply the same discipline per episode, which is why their catalogues sound consistent across years of releases. Broadcast producers get ATSC A/85 and EBU R128 compliance without leaving the DAW. The deeper value is educational: watching how normalisation treats masters that were pushed too hard — and hearing the codec expose it — changes how you master the next record before any meter tells you to. It is the difference between delivering files and delivering masters, priced below the cost of learning that distinction publicly.

The Deal

At $39.99, MasterCheck v2 costs less than one round of remastering after a platform rejection — or one single that lands quieter than every competitor in a playlist. It is not a creative effect; it is insurance and information, the two things professional delivery runs on. Instant download: install it on your master bus today and never ship a loudness surprise again. Keep it resident on the master bus and every future delivery starts out already half-checked.
