Low Level Background noise

I am a new user, and need some help! I have made a voice recording, but in the background is the noise of a lorry. I have tried sound removal, but i have no sound example to give because the voice is over all of it!!!

How can I ‘seperate’ the voice from the background sound so I can delete it?

Any ideas

You probably don’t. The only noises that the Noise Removal Tools work with are continuous noises like hiss or air conditioner or fan noises. The only other tools need a stereo show. Or multiple microphones. The lorry is now a performer in your show.

Recording a live performance is much more difficult than people think. Just finding a quiet room can take you a long time.
