Text-driven editing of existing music, including filling a gap. Conditions. Meta research model on a 48 kHz stereo VAE latent with flow matching. Method. The paper lists editing tasks as inpainting/outpainting, looping, instrument or genre swapping, vocals removal, lyrics editing, tempo control and recording-condition changes, claims no prior approach showed high-fidelity generic style transfer across them, and evaluates with FAD, KL, CLAP similarity, edit-distance metrics and listening tests. Measured result. 64 inference steps; table latency 1.8 s (small) and 2.3 s (medium) vs 18.1 s for AudioLDM 2 (hardware not stated in the sections read).
