Normalize quiet speech audio
Low-volume recordings are harder to review and can reduce transcript quality. Normalization raises the overall level without changing the spoken content.
Use with trimming and cleanup
Normalize after trimming silence or irrelevant sections so the exported file focuses on the speech you need.

Can I make quiet audio louder?
Yes. The volume normalizer raises the peak level and exports a WAV copy.
Will this fix clipped audio?
No. If the original recording is clipped or distorted, normalization cannot restore lost detail.
