Is it actually possible to create electricity with soundwaves?

if you somehow convert the air pressure into electricity.
fire the soundwave at a piezoelectric material and then sure.

Pretty sure this is more or less what microphones do. My high school EM knowledge tells me that a vibrating magnetic field should induce a current in a properly-located coil.

Congratulations! You've invented the microphone

why dont we just generate power by having people shout into microphones at the power factory?

Why don't we wire people to the power to make them shout instead at the shouting farm.

Omg even better idea lets just get all the people from the mental asylum and put them into the sound power plant

Dayshift: AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

Nightshift: AAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!

We can even shock them with some of the electricity they generate to make them shout louder.

Things want to resist change in flux. So if you start to move a coil that is next to a magnet from vibration it changes the flux of the coil thus induces current.

I should say vibrations move the coil which changes the flux by moving it. Thus inducing emf. Better way to say it. Everything actually has this happen just emf is too low for high resistance things to matter.

Yes. eg piezoelectricity.
