 - Reference clips: clean single-speaker speech, up to ~20 s each — the more the better (any sample rate; mono or stereo).
 - You don't have to follow a strict turn-taking pattern; see the [demo page](https://finmickey.github.io/scena/) for more varied examples.
 - 60 inference steps, guidance ~7, and output durations up to ~20 s work best (the model was trained on ≤20 s scenes).
