Hello. Can you help me to increase only a voice audio? I work with Premiere Pro and Audio Audition.

This is impossible as far as I’m aware due to the fact that loud vocal music blocks out any chance of hearing what was being said. Voices were clear at the start of the clip but it got worse over time. My guess is it’s a mic mounted on top of the camera?

An ideal way to capture voices in future would be using wireless lav mics. This would pick up the voice and then some basic noise reduction can be performed. In this case it’s not possible to restore what cannot be heard unfortunately.

Yes, the microphone is on the camera! I didn’t think to give the speaker a microphone. In the future i don’t make this mistake.
