Hello there. Well, universidade, uni-ver-si-da-de and noite, noi-te. The Brazil is very big and there are sundries accents. Try say like this: Univer and cidade(city), now fast speak univercidade(it's written worng, but the song is right). Noite: When "e" is last letter of word and previous letter "d" or "t" the song of "e" become "I", but it's not grammar rule only regional manneirism, for example in the South of Brazil, they speak: noite, leite, cidade, maldade, chocolate. While here in São Paulo we speak: noiti, leiti, cidadi, maldadi, chocolati.
