I am a Masters Student and one of those who find it very difficult to concentrate in the class. During my last semester, I started using recorded(by the University) lectures for exam preparation and found this way to be way more effective (in terms of marks obtained in exams) and time efficient as compared to actually attending the lecture. During this semester, I am enrolled in a subject where lectures are not recorded. I specifically want to do well in this subject and therefore want to have audio recordings of the lecture. But I am afraid that if I seek the Professor's permission, my gut feeling says that I might not get it(I don't want to dot down my reasons here as I want the discussion to be focused) and of course lose my chance to record lectures in the future. This is a public university in the State of New York.
Can anyone tell me if I were to record his lecture without seeking his permission, will I be breaking the law?
