## What is Akbo?

Sing, hum or play one instrument — Akbo turns it into a staff score right away.

■ Great for
• Saving a melody before you forget it
• Seeing the notes of a song you sing
• Getting the vocal melody out of a band rehearsal or demo mix
• Writing down a tune to practise on your instrument

■ Features
• Three modes: Voice only (singing or one instrument) / With band (songs and band takes) / Vocal track (an exported vocal stem)
• Import audio files: m4a, mp3, wav, aiff (up to 5 minutes)
• With band: on-device AI separates the voice from the accompaniment before transcribing
• Detects tempo, meter (4/4, 3/4, 6/8, 12/8), triplets, key and key changes, and pickup bars
• Edit notes: tap a note to move it a semitone up or down, make it longer or shorter, delete it, or undo
• Add a title and lyrics
• Save as an image to Photos or share as PDF

■ Private by design
All audio analysis happens on your iPhone. Recordings and files are never uploaded.

■ Free to use
Recordings up to 15 seconds convert right away. Longer ones show a short ad while converting. Buy "Remove Ads" once to convert any length with no ads.

Note: depending on the recording and the song, some notes may be recognised differently — fix them in a few taps with Edit notes.
