## Frequently asked questions

### Can these tools restore audio perfectly?

No. They reduce defects, but missing detail and severe clipping may not be recoverable; strong processing can add artifacts.

### Should I remove hum or denoise first?

Start with hum removal or a notch for a steady 50/60 Hz tone; use denoise for broadband or changing background noise.

### Which click tool should I choose?

Use Click/Pop Fix for isolated events and Click Removal for repeated, especially vinyl-like clicks.
