Udio offers a remix feature that lets users upload their own audio or use a generated track as a starting point and have the AI produce a new version that matches a different style or extends the original composition.

Users can upload reference audio or take a previously generated track and apply remix, style transfer, or extension operations. The 'Remix' mode generates something similar to the uploaded audio; 'Style' creates a song matching the uploaded audio's vibe; 'Inpaint' lets users edit specific sections; and 'Session' opens a waveform-based timeline editor. Users must confirm ownership of any uploaded audio. This feature builds on the core generative AI model and is available to all registered users, with some advanced modes restricted to paid tiers.
