Camelot Wheel Guide
The Camelot Wheel er et værktøj DJs og producenter bruger til harmonisk blanding. Hver nøgle tildeles et nummer (1-12) og bogstav (A for mindre, B for større). For harmonisk kompatible overgange, mix spor, der er:
- Samme kode (f.eks. 8A til 8A) - Perfekt harmonisk match, nul tonale sammenstød
- Tilknyttede numre (f.eks. 8A til 7A eller 9A) - Glat nøgleovergang med minimal spænding
- Samme nummer, switch letter (f.eks. 8A til 8B) - Mindre til større energiskift, stor til build-ups
- Plus et, switch letter (f.eks. 8A til 9B) - Energiboost med dominerende nøgleopløsning
Brugt af Rekordbox, Traktor, Serato, Blandet i nøglen, og VirtualDJ.
Understøttede formater
Maksimal filstørrelse: 50MB. For de bedste resultater, brug høj kvalitet lydfiler (WAV eller FLAC). Højere kvalitet input giver mere præcis nøgle og BPM afsløring.
Tips til nøjagtige resultater
- Brug kildefiler af høj kvalitet (WAV eller FLAC) for at opnå den bedste nøjagtighed
- Fuld længde spor giver mere pålidelige resultater end korte klip
- Sange med klar harmonisk struktur er lettere at analysere
- Hvis BPM virker forkert, tjek halv / dobbelt tid forslag
- Sange, der modulerer (ændringsnøgle) kan vise den dominerende nøgle
Hvordan detektering af nøgle og BPM virker
Avanceret audio analyse algoritmer undersøge spektral og rytmiske karakteristika af din musik til at bestemme sin tonale centrum og tempo med høj præcision.
Upload Your Track
Drag and drop any audio file onto the upload area, or click to browse your files. We accept all major audio formats including MP3, WAV, FLAC, OGG, M4A, AAC, AIFF, and WMA. Files up to 50MB are supported for thorough analysis of complete tracks.
AI analyserer lyden
Vores motor udfører chromagram analyse for at identificere pitch klasser og bestemme tonale center og tilstand. Onset detektering og autokorrelation algoritmer måler præcist tempoet. Analysen kører server-side på GPU hardware for hastighed og nøjagtighed, typisk fuldføre i 2-5 sekunder.

Who Uses Key & BPM Detection?
Musicians, DJs, producers, educators, and audio enthusiasts rely on accurate key and tempo data for their creative workflows.
DJing & Harmonic Mixing
The foundation of great DJ sets is harmonic mixing. Know the key and BPM of every track in your library so you can create seamless transitions between songs. Use Camelot codes to instantly identify compatible tracks. Mix in key to keep your audience engaged without dissonant clashes between songs. Essential for Rekordbox, Traktor, Serato, and VirtualDJ users who want to tag their libraries accurately.
Music Production & Sampling
Producers use key detection to find the key of samples, loops, and reference tracks before building a new song. Match your bassline, chords, and melody to the detected key. Layer samples from different sources that share the same key for cohesive productions. Instantly transpose samples to match your project key in your DAW.
Mashups & Remixing
Creating mashups requires knowing the exact key and BPM of both source tracks. Use our tool to identify compatible songs, then pitch-shift or time-stretch as needed. The Camelot system makes it easy to find songs that will blend naturally, even across different genres and decades. Analyze entire playlists to find the best mashup candidates.
Karaoke & Vocal Performance
Find the key of any song to determine if it falls within your vocal range. Singers and vocal coaches use key detection to identify whether a track needs to be transposed up or down for a comfortable performance. Essential for karaoke hosts who need to quickly adjust songs for different singers at live events.
Music Education & Theory
Music students and teachers use key and BPM detection for ear training, music theory exercises, and analyzing compositions. Verify your ability to identify keys by ear, study the tempo patterns of different musical eras and genres, and build a deeper understanding of harmonic structure across the repertoire you're studying.
Video Editing & Content Creation
Content creators and video editors use BPM data to sync cuts, transitions, and effects precisely to the beat of background music. Knowing the tempo ensures your visual edits land on musical beats, creating more professional and engaging video content for YouTube, TikTok, Instagram Reels, and other platforms.
Hvorfor bruge vores frie stemmeoptager?
Præcis nøgledetektion
Our key detection algorithm uses chromagram analysis, which maps audio frequencies to the twelve pitch classes of the Western chromatic scale. By analyzing the distribution and prominence of these pitch classes across the entire track, we determine the most likely tonal center and whether the piece is in a major or minor key. The algorithm handles complex harmonies, key changes, and modal ambiguity, providing confidence scores so you know how certain the result is.
Nøjagtig BPM-detektion
Tempo detektering kombinerer debut detection (identificering af starten på musikalske begivenheder som tromme hits og note angreb) med autokorrelation og spektral flux analyse for at finde den dominerende periodicitet i lyden. Vores algoritme præcist håndterer komplekse rytmer, syncopation, tempo ændringer, og genrer med tvetydige beat mønstre. Resultater omfatter decimal-præcision BPM værdier og halv/dobbelt tid alternativer for genrer som tromme og bas eller hip-hop, hvor det opfattede tempo kan variere.
Camelot & Åbn nøglenotering
Every detected key is automatically converted to both Camelot notation (used by Mixed In Key, Rekordbox, Traktor, and Serato) and Open Key notation. This makes it effortless to identify harmonically compatible tracks for mixing. The Camelot system assigns each key a number from 1-12 and a letter (A for minor, B for major), so compatible keys are always adjacent on the wheel. We also show relative keys, parallel keys, and compatible key lists.
Fuldstændig fri & ubegrænset
Unlike other key and BPM detection tools that limit free usage or require subscriptions, our Key & BPM Finder is completely free with no limits. Analyze as many tracks as you want, as often as you want, with no account required. No credits consumed, no watermarks, no hidden restrictions. All processing happens on our servers, so it works on any device with a browser, including phones and tablets.
