IMO - According to the court clerk, the case was recorded. There may be a way to listen to the audio or at least print a copy. It may be expensive.
You need to go to http://www.pacer.gov for Delaware and register for a Pacer account. Once you sign up and agree to the terms, you can print the pages at a cost. I'm not sure if the recording can be listened to, but I'm trying to determine that.
