Engine sounds like prop propeller engine

Howdy. I’m annoyingly back to ask a question I should probably direct to my local mechanic. My 2011 Tacoma has been running fine, never had an issue. Suddenly upon cranking this morning the engine sounded almost like a growl. I promptly turned it off and checked the oil. Oil was a little low so I topped it off, yet the issue persists. Can anyone make out or diagnose what happened? No check engine or oil pressure light on my dash. Link below to video of sound.

You are correct. Thanks for pointing me in the right direction. What a pain.

 

Sorry that happen to you.
