They are not all solving the same problem
"Drum transcription" covers three different jobs, and picking the wrong category wastes more time than picking the wrong product inside it.
- A chart for a well-known song. Someone has already transcribed it by hand, better than any model will. A human catalogue is the right answer.
- Your own audio turned into notation. A demo, a rehearsal recording, a song nobody has charted. This is what automatic transcription is for.
- Drum MIDI for a DAW. You do not want to read anything — you want the groove as data, to edit or re-trigger.
How to judge one, whichever you pick
Every product page claims accuracy, and accuracy swings wildly between songs on the same tool. The only test that means anything is yours. Run a song you know cold and check five things.
Kick and snare first
If the backbone is wrong, nothing else matters. Most tools get this right; one that does not is not ready.
Hi-hat against ride in a dense chorus
The hardest distinction in the job, and where tools diverge most. Human transcribers disagree here too, so treat it as a difficulty rating rather than a verdict.
The tempo and the bar lines
A part transcribed at double the real tempo is the same music and unreadable in practice. Check that the snare lands on 2 and 4, and that bar lines fall where you feel them.
Whether you can fix it
Every automatic transcription is wrong somewhere. A tool you cannot correct hands you a problem instead of a draft.
Whether you can get it out
MIDI for a DAW, MusicXML for MuseScore or Guitar Pro. Without an export the work is trapped wherever it was made.
The tools
| Tool | What it is for | Output | Where it is stronger |
|---|---|---|---|
| DrumAnalyzer | Your own audio, drums only, aimed at practising the part rather than filing it | Notation, step grid, MIDI, MusicXML | Play-along score with difficulty levels; corrections made in the page |
| Drumscrib | Your own audio, drums only | PDF, MIDI, MuseScore, audio | The longest-running dedicated drum tool; straightforward PDF workflow |
| Klangio Drum2Notes | Audio or a YouTube link; one of a family covering other instruments | Sheet music, MIDI, MusicXML | Polished product with mobile apps; the same company handles piano, guitar and voice |
| PlayDrumsOnline | Audio or a YouTube link, plus a large library of ready song pages | Notation in the browser, downloads | Big catalogue of pre-made song pages; mature play-along interface |
| AnthemScore | Desktop transcription of whole arrangements, not only drums | PDF, MIDI, MusicXML | Runs locally on your machine; handles full instrumentation |
| Songsterr | Human-made charts for a very large catalogue of known songs | Interactive tab in the browser | Human accuracy, and coverage no model matches on famous songs |
On accuracy claims, including ours. Published figures are measured on different material under different rules and do not compare across products. Nobody's number tells you how a tool will do on the song in your head. Ten minutes with your own recording tells you everything.
Where DrumAnalyzer fits
We do drums only, and we made a deliberate trade: rather than producing the best possible file, we produce a page you practise from. The transcription opens with the recording inside it, a cursor running through the score, any bar loopable, and a slider that rewrites the part at five difficulty levels — from a bare pulse up to the part as recorded — while the record keeps playing in full. That last one is the piece no PDF can have, and it is why the tool exists.
The model is our own, trained from scratch. That was not a preference: the strongest published open model, ADTOF, is licensed CC BY-NC-SA and cannot be used commercially. On a holdout of ten songs with human-made charts that our model never saw during training it scores micro-F1 0.952 against ADTOF's 0.937 on the same material — a small lead on a small sample, which is exactly why we would rather you judged it on a song you know than on that number.
Where we are weaker, plainly: toms are our shakiest voice, open hi-hat against ride in a busy chorus is unreliable, ghost notes come and go, and everything is read in 4/4 — odd time will confuse the bar lines. If you need a chart for a famous song today, a human catalogue beats us. If you need every instrument rather than the kit, a broader tool does.
Test it the way this page recommends. Here is a whole song already transcribed, so you can see the output before deciding whether to run your own music through anything.
Then run a song you know cold and work through the five checks. If it gets a bar wrong, the grid fixes it in a click — and telling us which bar is what makes the next version better.
