Why does it work on my uploads when database sites don't?
Database key sites only know released tracks. MelodyWiz analyzes the actual audio — your own productions, unreleased demos, live recordings, samples, anything.
What does the Camelot code mean?
The Camelot wheel maps keys to positions like 8B (C major) so DJs can mix harmonically: adjacent numbers and same-number letter swaps blend smoothly. It's the standard shorthand in every DJ library tool.
How accurate is it?
Clear tonal tracks detect reliably (the confidence score tells you how clear). Songs with key changes report the dominant key; atonal or percussion-heavy tracks are genuinely ambiguous and score low confidence.
Is it free?
Converting is free — 5 jobs a day, files up to 40 MB, no account. The preview shows the score with highlighted notes and plays the whole piece in the browser, so you can judge the recognition before paying. The downloads are a one-time purchase per piece, priced by length: up to 2 pages $2.99, 3–9 pages $5.99, 10+ pages $9.99 for MusicXML + MIDI; the Rehearsal Pack with per-part practice MP3s and slow mixes is $3 more. One-time payments — no subscription. Doing several pieces? Credit packs save you more: $9 unlocks 4 pieces, $19 unlocks 10.
What happens to my files?
Uploads are used only to run your job. Unpaid uploads and generated files are automatically deleted 7 days after processing completes. Please save any free results you need before then. Paid customer files are excluded from this automatic cleanup. We don't share them or train on them. You can delete any upload yourself at any time — the 🗑 on its card removes the file, everything made from it and any share link immediately. See our privacy policy.
