Help & support

Use the add button in the song list to select an audio file or a Music library track. You can edit the title and estimated BPM. Use audio you are entitled to process.

Open a song, select a part, then tap Extract or Remove. Lupli supports vocals, drums, bass and other instruments. Other includes guitar and keyboards together, not as separate parts.

Time and quality depend on the audio and your device. Keep Lupli in the foreground. Locking the screen or switching apps may interrupt processing. You can cancel during separation.

Move playback to a position and use the A or B placement button. Once both are placed, the section repeats. Drag A and B on the timeline to adjust them. Add a marker at the current position and edit its name or note. See the timeline help in the app for illustrations.

Protected or non-exportable tracks use Apple’s player with limited playback. AI separation, speed changes and recording alongside playback are unavailable, and A/B looping is restricted. Lupli does not bypass DRM.

Check Lupli’s microphone permission in your device Settings. Recording starts only when you choose to start it. Speaker audio and surrounding conversations may also enter the microphone.

The selected data is removed from Lupli. Original source files, shared copies and OS backups are managed separately.
