QuestionsQuestions
What can I bring in?
Audio files, and videos from the Photos app. Songs must be 10 minutes or shorter. There is no way to bring in a song directly from a music streaming service.
Is the harmony separated perfectly?
Results vary from song to song. Some lead vocals or instruments may remain, and parts of the harmony may come out faint.
How long does separation take?
Several minutes or more. It depends on the device, the length of the song and how warm the device is. You can practise songs you have already saved while you wait.
Do I need an internet connection?
The data used for separation is built into the app. Adding, separating and playing all work without an internet connection. That makes the app large, so Wi-Fi is recommended when you download it. A connection is used only for showing the price, buying, restoring a purchase, and opening pages such as support.
Is my audio sent to a server?
Separation runs on your device, and your audio is never uploaded to the developer's server for it. Songs and settings you have saved may be backed up according to your OS settings.
