Vocal Remover Karaoke - oolala

oolala: AI Vocal Remover, Karaoke Maker & Stem Splitter (100% Offline)
Remove vocals, split music into stems, extract acapella, and build karaoke tracks from any song or video, all offline and powered by on-device AI. No uploads, no internet, no account required.

oolala uses multiple on-device AI models, including Meta's Hybrid Demucs v4, HTDemucs FT, SCNet, and several other MDX-Net models, giving you studio-grade vocal separation and instrumental extraction directly on your phone. Whether you're a singer who wants an instrumental backing track, a producer isolating stems for a remix, or you just want to sing along without the original vocals, oolala handles it in minutes.
