By Sam Ridder — I build and run StemGrab on my own hardware, on my own. Who I am.Drop in a track and see its key, its Camelot code and its BPM — free, no account, no watermark. You get the seven stems from the same upload.
Full-quality stems. No account, no per-track fee. Same model and same 192 kbps (or lossless WAV) as the paid tier — tracks up to 15 minutes.
Call it bpm key detection, an mp3 to bpm reading, or reading the two numbers together — one pass over the audio returns both, free, no account. It's a song key and bpm finder free tool and a song key and bpm finder app in one — both come back from a single upload. A song key and bpm finder online session and a song key and bpm finder online free one are the same page — the tier only changes track length.
Your upload is deleted the moment the numbers appear. Want the stems from the same track as well? The full tool is on the home page.
Before a track earns a slot in a set, most DJs check two things: will the tempo ride along with the rest, and will the key clash. This gives you both from one drop — the key with its scale, the Camelot code for the harmonic check, and the BPM for the tempo check — instead of running the file through two separate tools to screen one track. Split the same track afterwards and the numbers stay above your stems.
Both numbers are read from the same audio, so both inherit the same limits — a half-time BPM reading and a relative-major/minor mix-up are the two common ones, covered in full on the BPM finder and the key finder. The one thing specific to using them together: when both readings are borderline at once — a tempo that could be half or double, on a track whose key sits right between relative major and minor — trust your ears over either number before you drop it into a set. On silence, or a clip too short to measure, you get "couldn't read this" instead of a guess for either one.
Screening a folder of candidate tracks before a gig is really two filters at once: which ones sit near the set's tempo, and which ones won't clash key-wise with what's already in — running both through separate tools doubles the work for every track you reject. Producers use the same two numbers to pitch a sample into a project or set the tempo before dropping stems in. Since you get the acapella and the instrumental from the same upload, the mashup and the numbers you need for it arrive together. Building something bigger? Stems to remix covers the full set. MP3 to MIDI turns the same upload into a file with the tempo and key already baked into the notes, one track per instrument.
Some ask how to check bpm, want a song bpm counter or a song bpm detector, or look for a key and tempo finder that reads both at once — which is exactly this page. Others search by a tempo range rather than a title, like songs at 120 bpm or in the 100-120 bpm range — songs 100-120 bpm is that same range said as a title-style phrase — this tool reads one file at a time rather than searching a library by tempo, but it's the fastest way to check whether a candidate track actually matches the range you're after. Looking specifically for songs that are 120 bpm rather than a nearby range? Upload a candidate and the exact reading tells you whether it actually lands on that number or just close to it. And a few want the key and tempo changed rather than just read: that's the song key tool and pitch changer, a key and bpm changer combo, once you have the reading.
Only need the tempo today? This doubles as a plain mp3 bpm finder — drop in the file and read the number without touching the key. Landed here from a vocal remover bpm finder search because you wanted the tempo next to stripped-out vocals? The same upload gives you both, so there's no second tool to open.
Search for a way to find bpm of mp3 files and you'll land here, reading the tempo straight off the audio. Ask for a song bpm and key finder together and that's exactly this page's output: both numbers from one upload. Look for a plain key and bpm detector instead and the same reading comes back in about two seconds.
Plenty of people would rather tap for bpm than upload a file, tapping the space bar along with the beat. Others search tap to bpm instead — tap along on the separate page if that's you. A few just try tapping bpm out by hand before reaching for an upload, which works fine for a steady rhythm. Or use online tap bpm for the same idea, right here without opening a second tab. Searching song finder tap instead? Same idea, same link. Others want to change bpm, ask what is bpm in the first place, notice a track changes bpm partway through, or look for a key bpm finder that reads both at once — which is exactly this page. Want to change bpm of song rather than just read it? That's the pitch changer next door — this page only measures.
Plain lookups make up a big share too — wanting to find bpm of song material, find song bpm, or find the bpm of any song, to detect bpm automatically, or run it through an online bpm counter or online bpm calculator. Calculating comes up just as often: to find key and bpm in one pass, how to calculate bpm, or to find bpm youtube — download the audio first with extract audio from video, then run the file through here. Some just want a bpm song finder or a song beat finder for the same number, or type find bpm and key instead of find key and bpm — all land on the same reading.
Whether you call it a key finder bpm combo, a bpm finder and key tool, or just want to find key bpm in one go, that's exactly this page. And if the question is really how to find bpm of a song or how to detect bpm at all — like an online bpm detector or a tunebat bpm alternative — the same upload answers it, no manual counting or how do you calculate bpm math required.
A large share of visitors already know the song and just want the numbers — 7 nation army bpm, beat it bpm, blinding lights bpm, bohemian rhapsody bpm, dancing queen bpm, despacito bpm, as it was bpm, cruel summer bpm, dance monkey bpm, california gurls bpm, or africa bpm — among the thousands of individual titles this same reading covers. We won't guess a number for a song we haven't read — upload the actual track and get the real key and BPM in about two seconds, whichever title you have in mind.
Yes — this page does both at once: upload a track and get the key, scale, Camelot code and BPM together, instead of running two separate tools.
Yes — no account, no watermark, no daily cap. It reads the file in about two seconds and doesn't queue behind the stem separation.
A DJ shorthand for the key — the key finder walks through how the numbers work. Short version: same code, or one number apart, mixes harmonically.
See the BPM finder's FAQ for why it happens. Short version: trust your own count over the reading.
Sometimes — the key finder's FAQ has the detail. Short version: relative major/minor mix-ups are the main one, and unclear audio says so instead of guessing.
Seven per song: vocals, drums, bass, guitar, piano, other, and a mixed instrumental (everything except the vocals), all as 192 kbps MP3 plus a zip of the lot.
No. Your upload is deleted the moment it's processed and the stems are wiped from the server within 45 minutes (24 hours if you bought a month pass — that longer window is part of what the pass is for). Nothing is stored, shared or used to train anything — see privacy.
Yes — that's what this page is: a single bpm and key finder, so you don't need one tool for the song bpm and a separate one for the key. Drop in the audio file and both numbers come back together, in about two seconds.
Upload the file here instead of using a song tempo finder that relies on tapping along — this reads the tempo and key directly from the audio in about two seconds.
Yes — StemGrab reads the musical key, the Camelot code and the tempo from every upload at no extra step. No account, no daily cap, and the result appears above your stems.
Yes. StemGrab analyses the key and tempo in the same pass as the stem separation, so the key, Camelot code and BPM all appear together before you download anything.
Yes — this page works as a bpm tracker and key finder together, so you're not running one tool for the tempo and another for the key.
Yes — and however you calculate bpm of a song, upload here and the number comes back in about two seconds, key included.
A trained detector reads the key and tempo straight off the audio — not a lookup table of known songs, so it works the same on a track nobody has heard before.
Not a search-by-number database — upload each candidate track and compare the key and BPM it returns to build a set by hand.
One upload — the key, Camelot code and BPM appear alongside the seven separated stems, including the isolated vocal, from the same file.
Yes — this page reads the key, Camelot code and BPM from one upload, so there's no need to check tempo and key separately on two different pages.
It reads the dominant tempo across the file; a track that speeds up or slows down partway through can land on the number that fits most of the song rather than every section.
Yes — upload the rough mix and the tempo comes back in about two seconds, well before you'd want to commit studio time to it.
It's harder than a clean studio track — background noise can throw the reading off, so trust your own count if the result looks unlikely.
A clip that's too short to measure returns a message saying so instead of a guessed number, so very short snippets may not give a reading at all.
Yes — upload the candidate track, read the tempo and key together, and decide whether it belongs in the set before you commit to mixing it in.
Yes — MP3, WAV, M4A, FLAC and video files all go through the same upload box and return the same tempo reading.
Yes — drop the file in and the tempo reads straight off the audio in about two seconds, no tapping required.
Upload the actual track — the page reads the tempo directly from the audio instead of guessing from a title or memory.
Yes — this page shows the key, Camelot code and BPM together from the same upload, not just the tempo on its own.
