One instrument per file.
What you get
Tell it the instrument
Bass, piano, guitar, vocals, synth or other. The hint sets the note range and the MIDI instrument, and cuts false notes.
Tune it by ear
Sensitivity, minimum note length and a single-line switch re-run instantly, with playback against your recording.
On the grid, in key
Tempo, meter and key are detected and confirmed by you; the MIDI and the score follow the grid you pick.
MIDI, MusicXML, score and piano roll
One upload, four results. The MIDI carries tempo and key; the MusicXML opens in MuseScore, Sibelius and Dorico; the score prints from the browser; the piano roll plays back with speed and transpose.

Which formats can I upload?
WAV, AIFF, FLAC and MP3, up to 10 minutes and 100 MB. Stereo files are mixed to mono before transcription.
Can I upload a whole song?
The model reads one instrument at a time, so a full mix comes back muddled. Split the song first with the stem splitter, then upload the bass, vocal or other stem here.
Which instruments work best?
Clean single lines: bass, a lead vocal, a lead guitar, a monophonic synth. Piano and strummed guitar work but need a look at the piano roll before you trust every chord.
Do I need an account?
It asks for your email once per browser; the link in the mail signs you in for 30 days, and your transcriptions stay in your history for a year.
What about drums?
Drums have their own tool, WAV to MIDI drums.
