What audio2guitar is
audio2guitar is a web app that turns audio recordings into guitar tablature, chord diagrams, and lyrics synchronized with the tabs. It separates guitar from a recording, identifies notes and chords, maps notes to fret positions, and produces notation. The maker says it detects more than 170 chord types and marks techniques such as slides, bends, vibrato, hammer-ons, pull-offs, and palm mutes. Free users can upload MP3 files; Pro also accepts WAV, FLAC, M4A, OGG, and AAC. Pro adds MIDI and PDF exports, separated vocal and instrument stems, per-stem MIDI, and playback speed adjustment from 25% to 100% while tabs stay synced and pitch remains correct. A valid Google account is required. The homepage reports 97.8% string assignment accuracy on the GuitarSet benchmark and says clean recordings with prominent guitar yield the best results. Most songs take 3 to 6 minutes to process, though longer or denser tracks may take more time. Pro use is subject to a rolling limit of 35 new songs per 7 days.
