If you mean soundbites, then, yes, you could translate O-Ton/O-Töne like that. But O-Ton is not necessarily a soundbite, but can also refer to a (written or spoken) quote. A soundbite is an audio-only recording, e.g. from a speech.

O-Ton is an abbreviation of "Originalton", and that would simply mean the original soundtrack.

"O-Ton Person XY" bedeutet umgangssprachlich einfach, dass man die Person XY zitiert
