HomeVinyl Pre-Master Check

Is your master
safe to cut?

A pressing plant will find the problems in your low-end phase and sibilance eventually — at the test-pressing stage, when it costs money. This check runs the same physics on your master now, against real cutting limits, for free.

A vinyl cutting master from a mastering house runs €60–80 per track. Knowing whether you need one costs nothing.

Questions

What does the vinyl pre-master check measure?

Five things a cutting engineer will check anyway: low-frequency phase correlation (out-of-phase bass can lift the needle), RIAA-weighted sibilance (harsh S sounds distort on the inner grooves), overall level versus cutting limits, subsonic content, and pre-echo risk. Each is scored against real pressing-plant specifications.

Why can a master that streams fine fail on vinyl?

Vinyl is a physical medium with physical limits. Wide, out-of-phase low end that sounds huge on headphones can make a groove uncuttable; bright sibilance that a DAC reproduces cleanly burns into distortion as groove speed drops toward the label. Streaming masters are routinely too hot and too wide for the lathe.

What is the difference between the LP and Maxi cut targets?

Groove geometry. A 12-inch maxi cut at 45 RPM has more room per second of music, so it tolerates more level and more bass width than a full LP side. Pick the format you are actually pressing and the limits adjust.

My track failed the check. Now what?

The report tells you which metric failed and by how much, so you or your mastering engineer can fix exactly that — usually narrowing the low end, de-essing, or pulling the level. Our Mastering Kit also renders a vinyl-safe cutting master automatically.

Does the check modify my audio?

No. It is analysis only — your file is measured, reported on, and deleted. Decisions at the lathe always belong to your cutting engineer; the report just means no surprises.

How long can an uploaded side be?

Up to 25 minutes, which covers a full LP side. Files up to 30 MB in WAV, MP3, FLAC, AIFF, M4A or OGG.

What is vinyl pre-mastering?

Elliptical EQ, groove limits, and why vinyl needs its own master.

What is stereo correlation?

The number that decides whether your bass can be cut at all.
