MASTERQC
BY MIKE TUCCI MASTERING

The last check before a master leaves the studio.

MasterQC analyzes finished masters — loudness, true peak, clips, clicks, dropouts, album consistency — and signs off with a client-ready PDF report. It runs entirely on your Mac. Your audio never leaves your machine.

A MasterQC delivery report: album verdict band and per-track summary with a clipped track failing the no-clip delivery profile
The delivery report — one PDF a client can read. Track 03 just failed a no-clip delivery spec at +1.03 dBTP; that's the point.

What it measures

Loudness & Dynamics

  • LUFS Integrated (ITU-R BS.1770) + loudness range
  • True peak (dBTP) and digital peak
  • PLR, RMS average / max / min, crest factor
  • Streaming normalization preview per platform
  • Album loudness consistency — spread, outliers, anchor

Forensics

  • Clipped runs, clicks, dropouts — time-stamped
  • Hum detection, DC offset, noise floor
  • True bit depth (16 padded in 24 gets caught)
  • Stereo correlation, balance, polarity
  • Tempo & key, spectrogram inspector

Delivery

  • Spec profiles: digital no-clip, CD Red Book, streaming, vinyl
  • PASS / REVIEW / FAIL verdict per track and per album
  • One-page-per-track PDF delivery report, your letterhead
  • SHA-256 + PCM-MD5 fingerprints on every file
  • A/B audition, AAC codec preview, sessions, CLI

How it works

01

Drop the album

Drag the masters folder in. Every track is analyzed in parallel against the delivery profile you choose.

02

Read the verdicts

PASS / REVIEW / FAIL per track — with the exact timestamps of every click, clip and dropout, so you fix instead of hunt.

03

Sign off with the report

Export one PDF under your studio's letterhead. The client sees the numbers, the checks that ran, and the fingerprints that prove which files shipped.
