Convert guitar to editable MIDI in your browser
Choose one guitar recording above. Miditap decodes it in this tab, estimates pitched note events, and creates a standard .mid file you can download and edit.
A single-note melody gives the detector one main pitch to follow. A chord is harder because several strings, octaves, overtones, pick noise, and ringing notes overlap at the same time.
How to turn a guitar recording into MIDI
- Record the cleanest guitar part you can, without drums or another instrument in the background.
- Choose that file in the converter. Decoding and note detection run locally in this browser tab.
- Download the MIDI, listen with a plain instrument, and remove fragments before changing the sound.
The output contains note instructions, not the sound of the guitar. It does not preserve the pickup, microphone, amplifier, effects, articulation, or room, and it does not separate strings or create multiple instrument tracks.
Supported guitar recording formats
The file must use a codec that the current browser can decode. The extension alone cannot guarantee that two files with the same container will open.
| input group | accepted extensions | what the converter reads |
|---|---|---|
| Common audio | MP3, WAV, FLAC, OGG, M4A, AAC | The decoded audio channels |
| Additional audio | AIFF, AIF, OGA, Opus, WebM audio | The decoded audio channels |
| Video recordings | MP4, M4V, MOV, MKV, WebM | Only the decoded audio track; pictures are ignored |
Two real acoustic-guitar tests
Both inputs were recorded acoustic-guitar performances, not synthesized fixtures. We converted the files with the same browser component shown above, downloaded each MIDI file, and parsed every note event.
Both intended pitch classes appeared, but ringing strings and harmonics expanded the result to 30 events.
All four chord segments contained their expected pitch classes. The result contained 40 events.
The selected recordings and generated MIDI files stayed on the device running the test.
| test | input | MIDI output | what matched | what needed cleanup |
|---|---|---|---|---|
| Separated notes | Acoustic guitar playing E and A over 4.000 seconds | 30 events · 3.936 seconds | E and A both appeared | B, G♯, C♯, D, octave duplicates, and short fragments also appeared |
| Strummed chords | Acoustic guitar playing C, G, Am, and Em over 9.366 seconds | 40 events · 8.922 seconds | Each chord segment contained its required pitch classes in order | Repeated short attacks appeared, plus one extra A1 at the tail after Em |
These are results from two specific recordings in the tested browser build. They are not an accuracy rate and do not predict the result for another guitar, room, microphone, performance, or effects chain.
How to clean the detected guitar notes
Start with the very short events around each pick or strum. Listen before deleting: some are real string attacks, while others are harmonics or repeated fragments of a sustained note. Then check octave duplicates, compare the bass note with the chord you played, and join fragments only when they belong to one sustained pitch.
For a melody, mute every event except the line you intended and check the pitches one phrase at a time. For chords, keep the notes that define the voicing you want rather than expecting the converter to identify chord names or separate the six strings.
Guitar to MIDI questions
Can Miditap convert guitar chords to MIDI?
It can detect overlapping pitches, but a chord is a harder input than a single-note line. In the four-chord test, the expected chord pitch classes appeared in sequence, while short repeated attacks and one extra tail note still needed cleanup. Miditap does not label chord names or separate strings.
Why did one guitar note become several MIDI notes?
A plucked string produces a fundamental pitch, harmonics, pick noise, and resonance from other strings. The single-note test found both intended pitch classes but also created octave copies, neighboring harmonic pitches, and short fragments.
Can I record guitar on my phone?
Yes. Record the part with the phone microphone, save it in one of the accepted formats, then open this page and choose the recording. A quiet room and one exposed guitar part give the detector less competing sound.
Will my guitar recording be uploaded?
No. The file is decoded, analyzed, and turned into MIDI in the browser tab on this device. This page does not send the recording to an upload endpoint.
Does this split chords or create multiple tracks?
No. The result is one detected-note track. Miditap does not separate strings, identify chord names, split instruments, or create a multitrack arrangement.
