If you are facing any criminal charges, I suggest that you consult a criminal defense lawyer. You may share your recordings with your lawyer, and see if your lawyer agrees with you about their content.

It would be sensible for you to refrain from any contact with any person who has accused you of harassment, and especially the former landlord who accused you of assault.

I suggest consulting a psychiatrist for an evaluation, as should anything come of this your mental health will become an issue.
