BPM & Key Finder
Upload any track or pick from your MusiCraft library. Get BPM, musical key, and Camelot code — analyzed privately in your browser.
Supports MP3, WAV, M4A, and FLAC up to 8 minutes. We analyze the opening section for speed — results are estimates, not studio-grade metadata.
For DJs & Producers
Built for harmonic mixing and quick prep
You need tempo and musical key (plus Camelot) for DJ prep, mashups, or sample checks — without opening a DAW or uploading private tracks to a random online detector. Many tools send your file to a server; MusiCraft analyzes in-browser with WebAssembly.
Musical key + Camelot
See the detected key and Camelot code for harmonic mixing and mashup planning. Verify critical release metadata in your DAW if needed.
Private by design
Analysis runs in your browser with WebAssembly. Your audio stays on your device — and when you’re ready, stems, mastering, and generation are in the same product.
How to use
Analyze a track in two steps
- 01
Choose your audio
Drop an MP3, WAV, M4A, or FLAC (within length/size limits), or pick a library track. Local analysis doesn’t upload your file to a detection server.
- 02
Read BPM, key & Camelot
Use BPM for sync and cueing, and key/Camelot for harmonic mixing plans. Re-check short clips or rubato performances if the estimate looks unstable.
