buzzing noise

Everytime I accelerate I hear a buzzing noise and its mainly when i start stepping on the accelerator. from stop to go is when I hear it

 

What do you mean from stop to go? Like you don't hear it unless you come to a complete stop? So if you slow down to 1mph then mash the gas no buzz, but if you slow to 0 mph and mash the gas buzzing?

How long does it buzz?

Have you been under and checked all exhaust shields are snug? Could be a faulty catalytic converter or muffler, insides can be detached and buzz around, but typically you would hear that on acceleration regardless of whether you came to a stop or not.

I'd record a video and post it to be honest.
