audio2guitar vs Ivory

audio2guitar is a web app that converts uploaded audio into guitar tablature, chord diagrams and lyrics synchronized to the tabs. Its process isolates guitar, detects notes and chords, maps notes to fret positions and creates the notation. Free users upload MP3 files; Pro also accepts WAV, FLAC, M4A, OGG and AAC. The maker says it detects more than 170 chord types and annotates hammer-ons, pull-offs, slides, bends, vibrato and palm mutes. Pro adds MIDI and PDF export, separated vocals, bass, drums, guitar and piano stems as MP3, per-stem MIDI, and playback from 25% to 100% speed while preserving sync and pitch. A valid Google account is required. The homepage reports 97.8% string-assignment accuracy on GuitarSet and says clean recordings with prominent guitar work best. Most songs process in 3–6 minutes. Plans include Free at free, Pro Monthly at $8.99 a month, Pro Annual at $59.99 a year, and One-time at $9.99, paid once.

Ivory uses AI to transcribe piano audio into editable sheet music and MIDI. Its model is trained specifically for polyphonic piano solos. The web app accepts MP3, WAV, MP4, and standard MIDI files up to 15MB, as well as YouTube links. Users can edit notes by moving, resizing, or deleting them and apply smart quantization; synchronized score and piano-roll views, chord detection, hand separation, tempo control, and looping support review. Exports are available as PDF, MusicXML, and MIDI, and notation files can be imported into Sibelius, Finale, and MuseScore. Ivory lists workflows for Logic Pro, Ableton Live, FL Studio, Cubase, and Reaper, while its audio-to-MIDI DAW plugin integration is coming soon. The free plan costs nothing and includes unlimited transcriptions, but Performance MIDI previews are limited to 30 seconds. The yearly plan costs €59 a year and adds full-length Performance MIDI, advanced editing, and the premium AI model. The iOS app requires iOS 16 or later; videos exported without a subscription have an Ivory watermark.
