the truth about every track
BPM, key, audio quality. Verified locally on your Mac. Four DSP engines vote, the verdict is written back into the file. 100% classifier. Zero generative. Zero cloud.
“A label, not an opinion. A truth, not a guess.”
the problem
79% of "lossless" WAVs in our 1,000-file test were rebadged MP3s. Promo bitrates unknown. Old MP3s in the back of the collection. Drop one on a six-figure rig and the room hears it.
the discipline
Layer 1: four open-source engines vote (Essentia, Librosa, Aubio, Madmom). Layer 2: a CoreML classifier in development, built to lift key detection past 90%. SHA-256 dedup. No decoder, no generative path anywhere in the network.
the output
A file that finally tells the truth. Rekordbox, Serato and Traktor inherit the corrected tags as if the publisher had shipped them right. The library settles.
