My first thought is oil pressure buzzer.

But.... it's pretty quiet in the file you posted, so maybe a relay going hinky?

I would check if it's happening at stand still at idle or higher rpm.
If no, maybe something in speedo is buzzing. If yes, I'd look toward
electrical. Try driving with the cluster cover off. See if that
doesn't help pinpoint where it's coming from.
