Next door neighbor calls the cops. Options

[Sentinel23]

So I have this ~28 yr old lady for a neighbor. She's a post-grad student studying Biology and I thought she would be leaving the apartment since the lease ended last night (i.e. Aug 15th). She had told me that she would not be renewing the lease.

I try not to be loud at all since the walls at Honeycomb are paper-thin.

The first weekend I moved into the Apartment, I got a note on my door from her. I watched an episode of LOST at around 1 AM on a Saturday. Okay, fine. I started using my headset and rarely unplug it unless I'm playing music during the day. I also left a note on her door telling her I was sorry and if she felt I was loud she could always just knock on my door. I knocked on her door on two different occasions when she was at home to talk to her personally but she wouldn't open it.

The second weekend, I stayed up again on Saturday playing some BF2142 (PC game). I was on Ventrillo but I had barely spoken anything and I'm 100 percent sure I did not yell. I barely uttered words like "thanks for the ammo", "Good one" or "Faaaaaawk" just loud enough to be heard on a headset. Yet I got a note on my door on Sunday morning saying that she would notify the apartment management etc etc. I again wrote a note, tried knocking - no response.

Then for more than two whole months, I was silent at night including weekends. I stayed up but it was mostly studying, I never played music through speakers or uttered a word till last night when her lease was up my best friends in Austin were back home from Germany on Thursday so we decided to play L4D from 2 AM to 4 AM. I walked outside her apartment the AC wasn't on and the windows were shut. So I assumed no one was at home.

Then at 4 AM cops are at my door telling me there was a noise complaint. I apologized to the cops. I asked them if I was loud and they said "not right now". I was still talking freely till the cops knocked on my door so not like I silenced myself. I even told them that both my immediate neighbors were gone and that was the only reason I chose to play PC games. After they left I went outside and saw that her light was on. Oops?

Okay, this time I'll admit that I was kinda loud, but not yelling. I was just talking. I wasn't even that loud since the conversation was kinda one-way (I was the only one using a headphone). But call the cops>!? There were other options (like knocking on the door)...

Anyways, I need some ideas on how I should tackle this situation. I know that the first time the cops give me a warning that is in effect for a year. The second time I get a citation.

I just (6 AM) put a note outside her door saying "Ouch! I thought you wouldn't be staying after the lease term. That really sucks for me. I was hoping I would get a new neighbor that wouldn't be such a psycho and call the cops on me for one Saturday night of in-game chat while playing on my PC. Do you think you will be leaving soon? You can leave a note on my door when I fall asleep tonight (IF I fall asleep) -308A + smiley face with boom-box"

LPD doesn't issue written warnings, just verbal.
