About this app

Separate vocals, instruments, and center-channel audio directly on your Android device. Import a song, inspect its waveform, choose a separation mode, and move from processing to playback, remixing, and export in one streamlined workflow.

AI separation modes

- 2-stem separation: split a mix into Vocals and Instrumental.
- 5-stem separation: create Vocals, Drums, Bass, Piano, and Other tracks.
- Center-channel extraction: isolate or reduce center content in stereo recordings, useful for vocals and accompaniment.
- Hardware acceleration: use compatible GPU acceleration when available, with automatic CPU fallback.

Import and analysis

- Choose audio from the in-app music library or your phone.
- Extract audio from video files.
- Import audio from a direct network link.
- Receive audio shared from other Android apps.
- View detailed waveforms, drag to seek, preview audio, and adjust input gain before separation.

Playback, results, and export

- Preview individual separated tracks with waveform-based seeking.
- Select exactly which stems you want to save.
- Export as M4A, AAC, MP3, WAV, AIF, or FLAC.
- Keep projects in Recent Extractions and reopen them without running separation again.
- Organize imported audio, separated tracks, and remixes in the built-in music library.
- Rename, preview, and delete saved audio.

Multitrack remixing

- Open 2-stem or 5-stem results in the remix workspace.
- Adjust each track's gain or mute individual tracks.
- Seek directly on the waveform while previewing the mix.
- Export a new mixed audio file to the music library.

Sharing and usability

- Share saved audio through Android.
- Download music library files to a computer through Wi-Fi sharing.
- Use light or dark appearance.
- Keep playback working when the screen orientation changes.

Core separation and audio processing run on the device. Processing speed depends on track length, selected mode, audio format, and device hardware. Separation results may vary with the original recording and mix.
