Guitar to MIDI: convert one clear guitar phrase locally

Q: Does this convert a full guitar song to MIDI?

No. MIDI Convert outputs one melody line at a time. First prepare the guitar line you want to follow as a monophonic source, then convert it. It does not isolate guitar from a full mix, separate stems, transcribe chords, or build a complete arrangement.

This converter outputs one melody line at a time. First prepare the single guitar line you want to follow, then convert that monophonic source to MIDI and check that its contour still follows the phrase you played.

Short answer: this is a single-line melody converter by design. Isolate or choose one audible guitar line before conversion; it does not split a full song into stems, chords, drums, tab, or separate MIDI tracks.

Choose the right guitar phrase

Start with one note at a time and a clearly audible guitar line. A short clean riff, picked melody, or single-note lead gives the pitch detector one line to follow. Five to fifteen seconds is enough to hear the opening, largest movement, repeated note, and first pause.

Do not use a full band mix as a guitar-isolation test. Backing chords, bass, drums, vocals, effects, and distortion can make the detected line follow another sound instead of the guitar phrase you intended.

One-line design boundary

The detector makes one autocorrelation pitch estimate per analysis frame and groups those estimates into one note line. Its alternate Bass line setting only changes the analyzed frequency range; it is not a polyphonic or multi-note mode. Prepare the line you want to convert before using this page.

The shared controlled-source check uses 10 generated mono 44.1 kHz, 16-bit PCM WAV repetitions per condition; Balanced Melody / solo instrument mode; a 2048-sample window; a 1024-sample hop; and median reporting. A target is retained only when exactly one output overlaps it by at least 50% and is within 50 cents. Detector version SHA-256: DDA185AC8FB6A179A4FCFA73FD4197ACC95B8B6F59B233F5D3E330F596309F9F.

These are controlled synthetic source checks, not a general guitar-transcription accuracy promise. They measure this single-line mode under the listed conditions only.

Check the MIDI before you edit it

Choose a short local MP3, WAV, M4A, FLAC, OGG, or another browser-decodable file containing the guitar phrase.
Keep the converter in Melody / solo instrument mode and download the generated .mid file.
Open it in a piano roll and compare the opening, largest movement, repeated note, and first pause against the recording.

Keep a result when the broad note shape follows the guitar. Correct a local timing, octave, or pitch mistake in a MIDI editor. Retry with a clearer phrase when the MIDI follows chords, noise, or a different instrument.

Can I convert guitar to MIDI online?

Yes, for a short local recording with one clear guitar note line. The converter above processes the file in your browser and produces an editable MIDI sketch you can inspect before deciding whether it is worth editing.

Does this convert a full guitar song to MIDI?

No. MIDI Convert outputs one melody line at a time. Prepare the guitar line you want to follow as a monophonic source first. It does not isolate guitar from a full mix, separate stems, transcribe chords, generate tablature, or build a complete arrangement.

What guitar recording works best for MIDI conversion?

Use a short dry phrase with one note at a time and a clearly audible guitar line. Avoid backing chords, drums, vocals, heavy distortion, and effects that compete with the intended pitch.
