StemScriber
Slow songs down to learn them
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Learn any song the way you actually practice it.
StemScriber pulls a song apart into its separate instruments so you can hear exactly what you're trying to play — then slows it down so you can keep up.
What it does:
• Isolate any instrument — mute the vocals and band, solo just the guitar (or bass, drums, piano, vocals). Finally hear the part that was buried in the mix.
• Slow it down — drop the tempo without the pitch turning to chipmunks. Sit with a fast riff at half speed until it's under your fingers.
• See the chords — a chord chart is generated for the song so you can follow the changes while you play.
• Tuner + fretboard — built-in, free, no sign-up.
Made for the way musicians really learn — by ear, slowed down, one part at a time. Whether you're working up a cover, learning a solo, or figuring out a bass line, StemScriber gets you from hearing it to playing it faster.
Use it with music you own or have the rights to.
Chord detection is a strong starting point, not a perfect transcription — it gets you playing fast, and you can trust your ears for the rest.
