## Frequently asked questions

### When should I use Audio Mix instead of Audio Overlay?

Use Audio Mix for the ongoing balance of several tracks. Use Audio Overlay when one source must start over a base at a defined time while the base remains present.

### Does a crossfade replace a level check?

No. A crossfade smooths a handoff between two files, but it does not prove that the complete mix is balanced or that its peaks are safe.

### How can I avoid clipping after adding an overlay?

Leave headroom, listen to the combined passage, and inspect the output peaks. If it clips, lower the contributing track levels and check the revised mix.

### Does this workflow split clips or remove noise?

No. It covers balance, mixing, timed overlay, and crossfade only. Segmentation and noise restoration belong to separate workflows.
