Norah Studio
Stem Separation, Reimagined
Free · In‑App Purchases
Separate any song into vocals, drums and instrumental on your iPhone or iPad. Loop it, slow it down, change its key and play along.
Norah Studio takes a song apart, right on your iPhone or iPad. Open a song you have, from Files or any app that shares audio, and Norah Studio separates it into vocals, drums and instrumental while you listen. The start is ready almost at once, and the rest fills in as you play.
Play along with the band, sing over the instrumental, learn a drum part or build a practice loop:
- Solo or mute any track, and set each one's level.
- Change the tempo without changing the pitch, or transpose by semitones.
- Loop any passage by bars.
- See the chords of the song as it plays.
- Scratch the song like a turntable: drag across the tracks while it plays.
Shape every track with a full effects rack: an equalizer on every track, plus Reverb, Delay, Saturation, Filter and Tape. On the vocal: Melody Synth, which plays the vocal line as a synth, grand piano, electric guitar, trumpet, accordion, harmonica or music box; Harmonize, which sings backing voices over the chords Norah Studio detects; Pitch Corrector, Gate, Vocoder and Vocal Chop. On the drums: Beat Swap, which replaces the beat with Techno, House, Drum & Bass, Jersey Club, Trap, Reggaeton, Afrobeats and more, plus Beat Repeat, Halftime, Slice Shuffle and Tuned 808. On the instrumental: Resonator, Bassline, Trance Gate, Reverse, Tape Stop, Spectral Freeze, Granular Cloud and Sidechain Pump, which also works on the vocal. Four visualizers, Pitch Trail, Ridgeline, Horizon and Eclipse, draw a track as it plays.
Every song you open becomes a project that reopens exactly where you left it. Songs opened from Files are read where they are, never copied. Save each track, or all of them at once, to Files with your effects, tempo and key applied, or export the melody and chords as a MIDI file. On iPhone, share your mix as a vertical video for your stories. Map any control to a MIDI controller with MIDI Learn.
Made for touch: tap to jump, drag to scrub, pinch to zoom. On iPhone the desk folds into one column, and the song keeps playing with the screen locked. On iPad, hold a chord to see how to play it on guitar and piano; with a keyboard, Space plays and 1 to 3 pick a track.
Your music stays on your device. Everything runs on your iPhone or iPad: no uploads, no account, no data collected.
Norah Studio Pro unlocks unlimited songs. It is available as Norah Studio Pro Monthly, an auto-renewing subscription of one month, or as Norah Studio Pro Lifetime, a one-time purchase that never renews. The first five songs are free. One purchase works on iPhone, iPad and Mac with the same Apple Account. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. To manage or cancel it, open Settings, tap your name, then Subscriptions.

A big update.
• Melody Synth: the vocal line played as a lead synth, grand piano, electric guitar, trumpet, accordion, harmonica or music box.
• Harmonize, rebuilt: a choir of backing voices that follows the song's chords.
• Vocal Chop, rebuilt: the voice cut into syllables and replayed in eight patterns.
• Tape, rebuilt: the small, honest sound of a phone on speaker.
• Four visualizers: Pitch Trail, Ridgeline, Horizon and Eclipse draw a track on the beat.
• Export MIDI: the melody, the chords and the tempo of a song, as a MIDI file.
• Save video on iPhone: a vertical video of your mix, ready for your stories.
• Changing the key keeps the three tracks perfectly together.
• Three tracks on every device: vocals, drums and instrumental.
• A new effect stack on iPhone and a new purchase screen.
• Compressor, De-esser and Groove Shift have been retired.
• Fixes: a project now reopens with its loop playing, and errors show as a small notice instead of an alert.
