Stem separation
Separate vocals from instrumentals, or isolate stems such as drums, bass, guitar, piano, synthesizer, strings, and wind instruments from songs or videos.
Overview
LALAL.AI is an AI audio separation platform for removing vocals, isolating instruments, cleaning spoken audio, and generating voice transformations. It started as a vocal remover and now includes stem splitting, voice cleanup, voice changing, voice cloning, echo and reverb reduction, and enterprise API access.
The service is designed for both casual and professional use. Users can upload audio or video files, preview the extracted stem, and download results in supported output formats. The pricing page shows a Starter plan, paid Lite and Pro plans, unlimited Relaxed Queue minutes on paid tiers, and Fast Queue minutes that vary by plan.
