Camelot 轮式指南
Camelot 轮是一个用于调和混合的工具 DJ 和 制片人。 每个密钥都配有数字(1-12)和字母( A 用于小密钥, B 用于大密钥 ) 。 对于协调兼容的转换, 混合轨迹是:
- 同一代码 (例如,8A至8A) -- -- 完美口音匹配,无声波冲突
- 相近数字 (例如,8A至7A或9A) -- -- 最不紧张的平稳关键过渡
- 相同数字, 切换字母 (例如,8A至8B) -- -- 从小到主要能源转换,对建设有很大影响
- 加1,换换字母 (例如,8A至9B) -- -- 以主要关键分辨率促进能源
由Rekordbox、Traktor、Serato、混合键和虚拟DJ使用。

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.
为什么使用我们的免费录音机?
精确密钥检测
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.
BPPM 精确检测
Tempo 检测将突发检测( 识别鼓声和笔记袭击等音乐事件的开始) 与 自动关系和光谱通量分析相结合, 以找到音频中占主导地位的周期。 我们的算法精确地处理复杂的节奏、 同步、 节奏变化和模棱两可的节奏模式。 结果包括小数- 精度 BPM 值和半/ 双倍时间的替代方法, 如鼓、 低音或嘻哈等, 其想象的节奏可能不同 。
Camelot 打开密钥标记( O)
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.
完全自由和无限制
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.
