Step-Audio-EditX

Step-Audio-EditX treats editing as constrained generation over stable timestamps. You can replace words, shift cadence, remove noise, translate voices while preserving style, and synthesize fills that match room tone and mix. Region masks keep changes local, reference clips lock timbre, and exports include aligned transcripts and cue markers so DAWs can ingest results directly. The system balances fidelity and speed for podcasts, dubbing, support agents, and rapid sound design.
