Built to be trusted with your release
Measured, never guessed
Every number on this site comes from signal analysis: phase correlation, loudness metering, key detection, hook recurrence. The same math cutting rooms use.
Your audio stays yours
Files are processed and deleted. Playlist blueprints are statistics built from public 30-second previews — the previews are discarded after measurement.
Honest verdicts
When a master fails a vinyl check, we say FAIL and show why. Reports you can hand to your engineer without translating.
Questions artists ask
What happens to my uploaded audio?
It lives in a temporary job folder while the analysis runs, then it's deleted. Your results page keeps the numbers — BPM, key, verdicts — never the audio.
How accurate is the hook detection?
On a validation set of well-known commercial tracks, a defensible hook lands in the top three windows for nine tracks out of ten. You always get all three candidates with instant playback, so your ears decide.
What exactly is a playlist blueprint?
A statistical profile of how a playlist actually sounds: spectral shape, timbre, dynamics, musical density — measured from public 30-second previews of its current tracks. Your track is compared against those statistics, hook to hook.
Who writes the pitch texts in the Kit?
A language model drafts them — from your track's measurements and the tags you confirm, with a hard rule: no claim without a measurement behind it. You get three drafts to edit, not a wall of adjectives.
Does the Vinyl Kit replace my mastering engineer?
No. It prepares cutting-safe files and a report that makes your engineer's day shorter. The final call at the lathe stays human.
