MASTERQC
BY MIKE TUCCI MASTERING
MasterQC runs the full delivery quality-control battery on every finished master: loudness, true peak, clips, clicks, dropouts, album consistency and more — analyze and confirm measurements and sonic ballistics easily.
The final step in every mastering engineer's workflow — Quality Control. Generate a PDF report for verification. Your audio never leaves the room or your computer.
Inter-sample overs, one-sample dropouts, 16 bits padded into a 24-bit file — time-stamped, jump-to-able.
PASS / REVIEW / FAIL per track against the delivery spec you choose. Green means done — not “probably fine.”
One PDF under your letterhead, fingerprinted to the exact files that shipped. Attach it and close the thread.
LUFS Integrated (ITU-R BS.1770) · loudness range
True peak (dBTP) · digital peak
PLR · RMS avg / max / min · crest factor
Streaming normalization preview per platform
Album consistency — spread, outliers, anchor
Clipped runs · clicks · dropouts — every one time-stamped
Hum detection · DC offset · noise floor
True bit depth — padded 16-in-24 gets caught
Stereo correlation · balance · polarity
Tempo & key · spectrogram inspector
Spec profiles: digital no-clip · CD Red Book · streaming · vinyl
PASS / REVIEW / FAIL per track and per album
One-page-per-track PDF delivery report
SHA-256 + PCM-MD5 fingerprints on every file
A/B audition · AAC codec preview · sessions · CLI
Drag the masters folder in. Every track analyzes in parallel against the delivery profile you choose — a full album in about the time it takes to pour a coffee.
PASS / REVIEW / FAIL per track — with the exact timestamp of every click, clip and dropout, so you fix instead of hunt.
Jump to the flagged sample, audition the moment, re-bounce, re-drop. The re-analyzed track keeps its place in the session. The ears stay yours — the checklist stops being one.
Verdicts are always per-profile — the same session re-checks against each destination's limits in one click, and the report names the spec it was judged against.
The normalization preview auditions your master in real time at each Digital Streaming Platform's playback level — the loudness-normalization reality check.
Sum to mono in one press — the radio check, the club check, the phone-speaker check.
Solo the side signal to hear exactly what stereo processing added — and what vinyl will fight.
Polarity flip for instant cancellation checks against a reference or an earlier pass.
Swap L/R to break symmetry bias — imbalances jump out when the image flips.
Plus an AAC codec preview — hear the encode a streaming service will make of your master, and see its true peak — and a full spectrogram inspector.
Select two or three tracks and cycle A / B / C — every contender level-matched to A, so you compare masters, not volumes. The playhead keeps its position across switches: the same chorus, through each candidate, at the same loudness.
Track-to-track spread with outliers flagged, an album anchor line, and quietest / loudest callouts in LU.
Every track's spectrum overlaid on one plot — the odd one out shows itself.
Side splits by size and speed, side-length caps, and an inner-groove caution when the hottest track sits last.
Album runtime against the CD ceiling, gap timing, and an album-level verdict beside the per-track ones.
The report is one PDF under your letterhead — verdicts, the numbers behind them, and the checks that ran.
A non-engineer reads it in a minute; an engineer trusts it in ten seconds. Include it in the delivery email for clients, or use it for in-studio verification.
The last check before anything leaves the studio. Full albums, delivery-spec verdicts, and the signed report your invoice rides on.
Verify bounces before they go up the chain — clips, dropouts, DC, true bit depth. Know it's clean before mastering ever hears it.
Check what you were delivered. Drop the files in and read the verdicts — no metering degree required.
QC incoming masters before they ship to DSPs. Batch a catalog drop, keep the PDFs on file, and hold every delivery to the same spec.
MasterQC is made by Mike Tucci Mastering. Every check exists because a real delivery needed it. No telemetry, no subscription, no roadmap theater — just the last step of the mastering workflow, a tool to bulletproof final delivery in full confidence, and done properly.
