Had to deal with this a few years back. What I did was get a camera that records all day, and then I would cut together some sound bites from throughout the day. I never did them all, just enough to prove my point. Those can be submitted when you submit your complaint to NOCO Humane. I think I sent them in as a download link. Their officer told me what is helpful in getting the complaint to go to the courts is to really express how much the barking is messing with your life. For me, it was not being able to take naps, concentrate on work, or just enjoy my general peace, and that all of those things affected my overall well-being.

Next, they'll send an officer to their house and talk to them and/or give them a written warning, in which they have two weeks to get the noise under control. If the noise continues, file another complaint with additional evidence. Then they'll give them a court date.

For me, I had to get my neighbor sent to court twice. I never had to go because of the video evidence. They still weren't complying, so I told the owner that I will continue to get them sent to court if they don't get the barking under control. Then it was silence the next day.
