Every track gets its key, major or minor mode, Camelot code and tempo together, plus half-time and double-time readings, so one scan answers both questions.
Drop in up to 50 files at once. They are read one after another on your device, and the results table fills in as each song finishes. Sort it by Camelot or BPM.
Select a track and the Camelot wheel lights up the keys that blend with it. The helper lists songs in key from your batch with their tempo gap, plus near misses.
Anyone who has to fit one piece of music to another. Six common jobs for key and BPM data.
Scan a new crate in one go, sort it by Camelot code and tempo, and see which tracks can follow each other without clashing notes.
Check an acapella and an instrumental side by side. If their keys sit one step apart and the tempos are close, the blend needs little work.
Get the key and tempo of every song on a setlist before rehearsal, then move any song that sits too high with the pitch changer.
Pick background tracks that share a key and a similar tempo, so a cut from one music cue to the next sounds planned, not jarring.
Know the key and BPM before you learn a song: set the metronome to the tempo and warm up on the scale of the home key.
Sort a running or class playlist by BPM, keep songs near your target tempo, and order them so the keys flow from track to track.
This song key and BPM finder sits between one-song checkers and desktop DJ software. Here is how they differ.

|---|---|---|---|
| Songs per run | Up to 50, analyzed one after another | One file at a time | A whole library |
| What you need | A browser, no install or sign-up | A browser, file by file | An installed app on a computer |
| Where audio goes | Stays on your device, never uploaded | Varies by site | Stays in your local library |
| Mixing help | Camelot wheel, matches, key shifts | Usually a key and a Camelot code | Key codes in the library view |
| Export | CSV with key, Camelot and BPM | Copy one result at a time | Saved in the app's library |

Most odd readings come from the audio itself. Run through these checks when a key or tempo looks wrong.
Each row has its own key and beat confidence. A low score is flagged in the table and means the file gives the analysis little to go on.
Tempo can be counted on every beat or every other one. If 87 BPM feels slow, the 174 reading is the same song counted twice as fast.
A minor and C major share the same notes, so a reading can land on either one. For mixing it matters less: 8A and 8B blend either way.
A DJ mix or medley holds several keys and tempos and gets one blended answer. Split it into songs; only the first 10 minutes are read.
Live takes and rubato pieces drift. Tap along on the tap tempo button while the track plays and use your tapped BPM for that row.
A full-quality file beats a phone recording of speakers. Room noise, crowd sound and heavy distortion blur both the notes and the beat.
Answers about finding the key and BPM of songs, Camelot codes and how this tool works.
Drop the song into the BPM and key finder above. It reads the file in your browser and shows the key, such as A minor, its Camelot code and the BPM, each with a confidence score. Add more files and they are analyzed one after another.
Yes. Choose or drop up to 50 files in one go. They are analyzed one after another on your device and fill a results table you can sort by Camelot code or BPM, copy row by row, or export as a CSV file for a spreadsheet or your DJ notes.
Yes. Tempo is the speed of a song and BPM, beats per minute, is how it is measured. So a key and tempo finder, a key BPM finder and keybpm tools all do the same job: name the key of a recording and count its beats per minute.
It is most reliable on music with clear chords and a steady beat, such as pop, dance and hip-hop. Every row shows separate key and beat confidence, and low scores are flagged. When a result feels off, check the relative key and the half-time reading.
The Camelot wheel numbers the 24 keys from 1 to 12, with A for minor and B for major. Select a track and the wheel lights up the keys that mix with it: the same code, one number up or down, and the same number with the other letter.
Analyze your tracks, then select one. The helper lists the songs in key from your batch with the tempo gap to each, plus songs one or two semitones away that you could move into key with the pitch changer before you mix them.
No. It finds one key and one tempo per file but does not work out the time signature. To find it by ear, count along with the beat and listen for the strong first beat of each bar: most pop songs are in 4/4 and waltzes are in 3/4.
It is free with no sign-up. Files are decoded and analyzed in your browser with signal processing, not AI, and never leave your device. It reads MP3, WAV, M4A, AAC, OGG and usually FLAC, up to 100 MB each and the first 10 minutes of a file.
