Panduan Roda Camelot

Roda Camelot adalah alat yang digunakan oleh DJ dan penghasil untuk campuran harmonik. Setiap kekunci diberikan nombor (1-12) dan huruf (A untuk minor, B untuk major). Untuk peralihan serasi harmonik, campurkan trek yang:

Kod yang sama (e.g., 8A ke 8A) - Persamaan harmonik sempurna, pertembungan nada sifar
Nombor berdekatan (cth, 8A ke 7A atau 9A) - Transisi kekunci lancar dengan ketegangan minimum
Nombor sama, huruf tukar (e.g., 8A ke 8B) - Pergeseran tenaga kecil ke besar, bagus untuk pembinaan
Tambah satu, tukar huruf (e.g., 8A hingga 9B) - Peningkatan tenaga dengan resolusi kekunci dominan

Digunakan oleh Rekordbox, Traktor, Serato, Mixed In Key, dan VirtualDJ.

Format yang disokong

MP3 WAV FLAC OGG M4A AAC AIFF WMA OPUS WebM

Saiz fail maksimum: 50MB. Untuk hasil terbaik, gunakan fail audio berkualiti tinggi (WAV atau FLAC). Input berkualiti tinggi menghasilkan pengesanan kekunci dan BPM yang lebih tepat.

Panduan untuk Hasil yang Betul

Guna fail sumber berkualiti tinggi (WAV atau FLAC) untuk ketepatan terbaik
Trek panjang penuh memberikan hasil yang lebih boleh dipercayai daripada klip pendek
Lagu dengan struktur harmonik yang jelas lebih mudah untuk dianalisis
Jika BPM kelihatan salah, semak cadangan separuh/dua kali masa
Lagu yang modulasi (ubah kekunci) mungkin menunjukkan kekunci dominan

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.

Pengesanan Kekunci Tepat

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.

Pengesanan BPM yang tepat

Pengesanan Tempo menggabungkan pengesanan permulaan (menyatakan permulaan peristiwa muzik seperti pukulan gendang dan serangan nota) dengan autokorelasi dan analisis aliran spektrum untuk mencari periodiciti dominan dalam audio. Algoritma kami dengan tepat mengendalikan ritme kompleks, sinkopati, perubahan tempo, dan genre dengan corak beat yang tidak jelas. Hasilnya termasuk nilai BPM ketepatan desimal dan alternatif masa separuh/dua kali untuk genre seperti gendang dan bass atau hip-hop di mana tempo yang dirasai boleh berbeza.

Notasi Kekunci & Buka Camelot

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.

Sempurna Bebas & Tak Terhad

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.

Our tool uses spectral analysis (via librosa) to detect the musical key and tempo of audio. It analyzes the frequency content to determine the key using chromagram analysis, and uses onset detection and autocorrelation to find the tempo (BPM).

BPM detection is typically 95%+ accurate for music with a clear beat. Key detection is 80-90% accurate and may occasionally suggest a relative key (e.g., A minor instead of C major). Complex or atonal music may produce less reliable results.

Yes, key and BPM detection is completely free with no account required and no usage limits. It uses zero credits for all users.

Camelot notation is a DJ-friendly system that maps musical keys to numbers and letters (e.g., 8A = A minor, 8B = C major). Compatible keys are adjacent on the Camelot wheel, making harmonic mixing easy. Our tool shows both standard key names and Camelot notation.

We support MP3, WAV, OGG, FLAC, M4A, and WEBM files up to 50MB. The tool analyzes the full audio spectrum regardless of format, though higher-quality files (WAV, FLAC) may produce slightly more accurate results.

Sudah tentu. Maklumat kekunci dan BPM amat penting untuk pengadunan harmonik. Guna kekunci yang dikesan dan notasi Camelot untuk mencari trek serasi, dan padankan BPM untuk peralihan lancar. Alat ini menggantikan pengesanan kekunci manual dengan analisis AI segera.

The web interface processes one track at a time. For batch analysis of entire music libraries, use our API to detect key and BPM for multiple files programmatically and build a tagged database of your collection.

The tool works best on individual tracks with a consistent key and tempo. DJ mixes or live recordings with tempo changes and key modulations may produce averaged or less reliable results. For mixes, consider analyzing individual segments separately.

The tool reports the primary key of the track. Songs with key modulations (key changes) will show the dominant key. For detailed key-change analysis throughout a song, you can use the API to analyze shorter segments of the track individually.

Ya, alat ini membezakan antara kekunci besar dan kecil (cth., C besar vs. A kecil). Ia juga memaparkan kekunci besar/kecil relatif kerana ia berkongsi nada yang sama tetapi mempunyai pusat nada yang berbeza. Notasi Camelot mencerminkan ini dengan pemilihan A (kecil) dan B (besar).

The tool primarily detects tempo (BPM). While it is optimized for common time (4/4), it can detect BPM in other time signatures like 3/4 or 6/8, though the reported BPM may need interpretation based on the actual time signature of the piece.

Detect the key and BPM of both tracks you want to combine. For a smooth mashup, choose tracks in the same or compatible keys (adjacent on the Camelot wheel) and similar BPMs. You can pitch-shift or time-stretch to align tracks that are close but not exact matches.
