About Norah Studio

Norah Studio, at norahstudio.app, is an app for iPhone, iPad and Mac that separates a song into vocals, drums and instrumental on the device. It is made by Oriol O'Callaghan. The models that do the separation ship inside the app, so nothing is uploaded, there is no account, and it works offline.

Open an audio file and three lanes appear. The song starts playing while the rest is still being separated. The site measures first sound at 1.1 seconds on a Mac and 1.5 seconds on an iPhone 16, using a song of 2 minutes 18 seconds in October 2026.

You can loop by bars, change the tempo without changing the pitch, transpose the key, and see the chords above the vocal. Each lane has an EQ and effects in the order you choose. Melody Synth plays the vocal melody on 19 instruments, and Harmonize adds a choir that follows the chords. You can export the three stems with their effects and the melody as MIDI, and MIDI Learn maps any control to a knob on a controller. Recent songs reopen as you left them.

It opens audio files the system can decode, including MP3, M4A and AAC, WAV, AIFF, FLAC and CAF, up to ten minutes long. It cannot open songs from streaming services. The maker says no separation is perfect, and that on a dense mix a little of the voice can stay in the instrumental. Tempo, key and chords are estimates and the app labels them that way.

Norah Studio needs a Mac with Apple silicon on macOS 15 or later, an iPad on iPadOS 26 or later, or an iPhone on iOS 26 or later.

Pricing: Free for the first five songs, with every feature included. Norah Studio Pro unlocks unlimited songs as a monthly or annual subscription or a one-time lifetime purchase, and one purchase covers iPhone, iPad and Mac on the same Apple Account. The US App Store lists Pro Monthly at $6.99, Pro Annual at $53.99 and Pro Lifetime at $95.99, and prices vary by country. Reopening a song you already separated is always free.
