Sound treated room VS Untreated room, what's the difference?

 Finding a recording space can be difficult if you rent. Today I am doing a demonstration between a closet space and how it sounds without any sound dampening materials vs adding foam wedges and moving blankets.

I recorded several mics in the room including the on-boarb mic if the camera. I then filmed each one and put it side by side to hear the difference.

In this video I test Yi 4k plus camera. Sony lapel Mic, Zoom red recorder, Tascam DR05, AKG mic and Sony Mini shotgun mic.

In the room I have two moving blankets, about eight foam squares, two bass wedges that you can't see in the room while I was filming.

There is still much work to be done and this is only an example. I will provide more details later.
