Let's Unmix -AI Stem Splitter

About this app

Effortlessly isolate and control your music—now with guitar separation! Separate any song into up to 6 individual tracks—vocals, drums, bass, piano, guitar, and other instruments—right on your device. No uploads, works fully offline. Turn any part into MIDI. Convert vocals, bass, piano, and now guitar to MIDI, then export it to your DAW or other music apps. Once separated, you can save and export these tracks to other apps, including your favorite DAWs (Digital Audio Workstations). Customize your playback by adjusting the volume and panning for each track independently, or even change the playback speed to suit your needs. With the waveform editor, it's easy to select specific regions for playback or export, giving you full control over your audio. Import your music directly from the Media Library, other apps, or cloud services like iCloud, Dropbox, Google Drive, and more. We support a wide range of audio formats, including mp3, m4a, ALAC, AIFF, FLAC, and WAV. Export your edited tracks in m4a, ALAC, AIFF, MIDI, or WAV formats. For the best experience, we recommend using music files with a 44.1kHz sample rate (CD quality). All exports are set to 44.1kHz to ensure consistent, high-quality audio output. One purchase unlocks all features forever. No subscriptions.
