SAXOPHONE RECORDING WORKFLOW
Upload or record a clean solo saxophone line, convert it below, and compare the detected notes with the sound you actually hear. The .mid file follows detected sounding pitch; this tool does not automatically rewrite notes as an E-flat alto or B-flat tenor saxophone part. For a player-ready score, import the MIDI into notation software, choose the correct saxophone instrument, and inspect its written-pitch view before sharing.
PROCESS ON THIS DEVICE
Start with a clear solo take. Preview the detected sounding notes before you prepare a written part in notation software.

CONTROLLED SIGNAL CHECK
A locally generated WAV contained two harmonic pitched tones with fundamentals at 440 Hz and 493.88 Hz, separated by silence. At the displayed defaults, this page completed conversion and showed two notes in MIDI range 69–71. No saxophone type was selected and no written-part transposition was applied. This is a synthetic software-path test, not a real saxophone accuracy result.
BEFORE EXPORT
The analysis reads frequencies from the audio and converts them into MIDI note numbers. It does not inspect the saxophone's name, key, or fingering. Check the note preview against the recording as a sounding-pitch comparison, not against a transposed printed part.
AFTER EXPORT
Import the downloaded MIDI, assign the appropriate saxophone instrument, and use the editor's concert-pitch or written-pitch display to inspect the result. Do not also shift all MIDI notes by hand unless you have verified what the editor already transposes.
| Your next use | What to keep or set | What to verify |
|---|---|---|
| Play the result beside the source | Keep the detected MIDI at sounding pitch | Compare audible note centers and timing with the original recording |
| Edit the melody in a DAW | Import the .mid as note events and assign an instrument | The instrument plays the melody in the intended sounding range |
| Give an alto sax player a part | Choose the editor's E-flat alto saxophone instrument | Check both concert and written-pitch views; do not transpose twice |
| Give a tenor sax player a part | Choose the editor's B-flat tenor saxophone instrument | Check both views and the sounding octave before export or print |
| Preview shows wrong notes already | Fix source or detection first; do not treat notation transposition as a repair | The sounding MIDI matches the solo recording before preparing a part |
INSTRUMENT FACT
Yamaha's saxophone guide identifies alto as an E-flat instrument and tenor as a B-flat instrument: a written C produces a different sounding pitch on each. The exact octave also matters, so choose the actual instrument in a score editor rather than adjusting by a guessed number of semitones.
CODE CHECK
The shared script estimates frequency from the recording, rounds it to a MIDI note number, and writes note-on and note-off events. It has no alto/tenor selector or transpose step. The preview and download therefore represent the detected sound, subject to any pitch-detection errors.
SOURCE CHECK
A band mix or doubled sax parts can contain several simultaneous pitches. This local detector chooses one pitch per analysis frame; use a solo track or isolated stem before expecting a clear single-line MIDI result.
EDITOR CHECK
MuseScore Studio documents concert pitch as the actual sound and written pitch as the instrument's notated part. Its instrument setting can apply the transposition automatically. Keep a copy of the unaltered MIDI and compare sound, concert view, and written view before sharing a score.
QUICK ANSWERS
Yes, for a clear single-line recording. Choose or record audio, convert in the browser, inspect the result, and download .mid.
No. It contains detected sounding MIDI notes, not a written saxophone score. Choose the appropriate instrument after importing into notation software.
Saxophones are transposing instruments. A score editor can show written notes for the player while the concert-pitch view matches the sound. Check the editor's instrument and view settings before moving MIDI notes.
No. The detector estimates one pitch at a time. Isolate one saxophone melody first.
No. The audio is decoded, analyzed, previewed, and converted in this browser.
