Echo from two mics

Hello I have been recording a podcast with another person in the same room. The problem is that my voice is being picked up by both mics and I have an echo. also when I try to monitor the recording there is a slight delay and it is distracting and hard to focus. so any suggestions preferably free ones would be a!
I have Audio-Technica ATR-1100 Unidirectional Dynamic Vocal/Instrument Microphone
and a CAD U1 USB Dynamic Recording Microphone
as well as two headset
a laptop and 4 desktops and 2 android tablets

The echo comes from the guest microphone picking up your voice from the wall behind the guest — assuming you two are facing each other across a table. The two microphone backs are properly facing each other, but multi-microphone setups only work in a quiet, echo-free room.

There are only two solutions: kill the room echoes or kill the separation between the microphone and the voice. The first can be helped along with sound proofing such as commercial foam panels or other efforts.

The second is usually done with headsets featuring highly directional microphones.

You can’t suppress echoes in software.

You could also change the room. I discovered by accident that storage rooms are not awful studios. The cardboard boxes break up the acoustics of the walls. Same with a garage/carpark assuming you have a normal garage full of trash. Again, any room with something to break up the bare walls.

One of our old buildings had a “sound room” with purpose-built non-parallel walls. It looked like a regular room until you measured it. It was remarkably successful in suppressing echoes with little or no actual padding.
