# StepAudio 3 Music Studio

Uses the original app.html studio interface, including song creation, instrumental generation, vocal arrangement, music covers, and playback.

Set `STEPFUN_API_KEY` in Space Settings → Secrets. The browser calls the Space backend; the key is never included in frontend assets. No local model or GPU is needed.

Optional variable: `SUBMITS_PER_MINUTE` (default 6), a global submission limit within the running process. This resets on restart. Use a private Space for initial testing of shared API credits.

Generation and history storage follow the original studio's browser storage behavior. Upstream requests use the existing project's `step-music` model and submit/query protocol.

Deployment: upload this directory as a Gradio ZeroGPU Space. Check `/healthz`, then submit a real song and verify playback once the Secret is configured.
