Google/Bing/Yahoo is your friend.
I found this in under three minutes:
§ 15A‑287. Interception and disclosure of wire, oral, or electronic communications prohibited.
(a) Except as otherwise specifically provided in this Article, a person is guilty of a Class H felony if, without the consent of at least one party to the communication, the person:
(1) Willfully intercepts, endeavors to intercept, or procures any other person to intercept or endeavor to intercept, any wire, oral, or electronic communication... (emphasis added by Citizen).
Looks like NC is what is called a "one-party consent" state. Generally, this means that if one party to the conversation consents, then it is legal to record. Generally, that one party can be you.
Wait a bit for others to chime in just in case the statute changed or there is some court interpretation of the statute that skews things.
Also, over the last year and half, federal courts have been finding that recording public officials is protected by the First Amendment. Cops were arresting people for video-ing them in public, citing wiretapping laws and pretending the First Amendment didn't exist. A few federal courts have ruled in favor of the arrestee's. I don't know the opinion of the federal court with jurisdiction over NC or whether that court has even ruled on such a case.
Best to wait until you get a few more answers that cite the law or court opinion, and then check out those citations yourself. You can also google reporters and videography of public officials in NC--professions that record frequently.
