This is a set of Audio Units including Loopback, Vocoder, Pitch Shifter, and Noise Suppression. A host application that can handle Audio Units is required for use. Loopback (In/Out/MIDI/Mixer): Connects to each other and transfers audio between host applications. MIDI signals can also be transferred. Please note that you might not do the recording inter app. Vocoder: This effect processes the sound of a synthesizer or other carrier with the input sound (modulator) and outputs it. It creates a so-called robot voice by inputting a voice or other sound. By default, Saw (sawtooth wave) is specified as the carrier, but it can also be input from a sidechain or Vocoder Input Audio Unit. Pitch Shifter: An effect that changes the pitch of the sound. Noise Suppression: A noise removal filter using RNNoise. This machine learning filter is optimized for voices. Gainer: An effect for adjusting the volume.

Stemify AI splits any song into 6 separate instrument tracks -- drums, bass, vocals, guitar, piano, and other -- right on your device. No internet required, no files ever leave your phone. HOW IT WORKS Import any mp3, m4a, or wav file from your library. On-device AI (no server, no upload) separates it into 6 clean stems in minutes. PRACTICE & MIX - Mute or solo any instrument to isolate what you want to hear or practice along with - Adjust playback speed using the automatically detected tempo, without changing pitch - Shift pitch up or down by semitones - Set A-B loop points to repeat a tricky section - Built-in metronome locks to the song's actual beat, not just a fixed click - Download your custom mix (e.g. the song minus guitar) as a single audio file to practice with anywhere PRIVACY FIRST Separation runs entirely on your device using Core ML. Your music is never uploaded anywhere. FREE TO USE Separate your first 2 songs for free. Need more? Watch a short ad to earn additional separation credits -- no subscription, no in-app purchase required. Perfect for musicians learning a song part by part, singers wanting an instant karaoke track, producers studying a mix, or anyone curious what a song sounds like without the vocals. Note: Please only use Stemify AI with audio you own or have rights to use. Separated stems are intended for personal practice, learning, and rehearsal.
