SUNG MELODY WORKFLOW
Record or upload one unaccompanied sung melody. Listen for the steady vowel in each note, then compare those pitched spans with the MIDI preview before downloading .mid. A consonant can interrupt the pitched vowel, and a long slide may pass through several detected notes. This tool estimates one pitch at a time; it does not transcribe lyrics or separate harmonies.
PROCESS ON THIS DEVICE
Use a short phrase with one sung note at a time; compare the note blocks with the source before changing controls.

CONTROLLED SIGNAL CHECK
A locally generated WAV used a quiet noise onset before each of two harmonic pitched tones, with a gap between them. The tones had fundamentals of 220 Hz and 293.66 Hz. With the displayed default controls, this page completed conversion and showed two notes in MIDI range 57–62. This synthetic test checks the conversion path; it is not a real singing performance or an accuracy claim.
FIRST LISTEN
In a sung word, the audible consonant can begin before the steady pitched vowel. Listen to the vowel center of each intended note. Compare that span with the detected note block instead of expecting a MIDI event to begin at every syllable's first sound.
SECOND LISTEN
A sung scoop, fall, or portamento passes through intermediate frequencies. If the melody is meant to contain only two target notes, write down where those targets are sustained and where the transition lies. The preview can expose extra stepped notes through the slide; it cannot infer your musical intention.
| Preview symptom | Check the source | Change one thing | Keep only if |
|---|---|---|---|
| Note begins after the word starts | Is the first part an unpitched consonant? | Compare against the sustained vowel, without moving a slider | The block starts near the first stable sung pitch |
| One scoop becomes several blocks | Does the source glide slowly through intermediate pitches? | Re-sing with clearer target-note holds; keep the controls fixed | The preview matches the intended target notes |
| Soft vowel disappears | Is a pitched vowel audible above the room noise? | Lower Silence threshold one step with the same file | The vowel appears without extra noise blocks |
| Brief consonant-like block appears | Is it shorter than a real sung note? | Raise Minimum note one step with the same file | The fragment disappears and intended short notes survive |
| A harmony becomes one unstable line | Are two voices sounding together? | Use an isolated single singer instead of another slider change | One melodic line is visible and audibly traceable |
CODE CHECK
The detector rejects frames below Silence threshold, then requires a repeated waveform pattern strong enough to estimate pitch. An audible consonant may fail the periodicity check. Lowering threshold alone cannot turn an unpitched sound into a reliable note.
NOTE GROUPING
Accepted pitches are rounded to MIDI notes, median-smoothed with nearby frames, then adjacent equal notes are grouped. Minimum note removes events shorter than its chosen duration. It may also remove a real quick note, so compare before keeping a longer setting.
OUTPUT BOUNDARY
The .mid file contains detected note events, not words, vowels, pronunciation, or the singer's recorded timbre. Assign an instrument or voice sound after importing the MIDI into music software.
REPEATABLE TEST
Before trying a control, note the intended pitch targets and audible boundaries. After conversion, compare the visible blocks and preview sound with that target. Do not treat a higher note count by itself as improvement.
QUICK ANSWERS
Yes, if it is a clear solo melody. Record or upload audio, convert in the browser, inspect the detected notes, and download .mid.
No. It writes note events, not lyrics or vocal audio.
A slide moves through intermediate pitches. This detector groups rounded pitch estimates into note events; re-sing with steadier target holds if you want fewer transition notes.
The initial consonant can be audible before the first stable pitched vowel. Compare the block with the vowel, not just with the word's first sound.
No. The shared converter estimates one pitch at a time. Use an isolated solo vocal line.
No. Audio decoding, note detection, preview, and MIDI creation occur in your browser.
