How would an audio recording most likely convey the characters emotions during the scene

I used to listen to drama or a romantic story on the radio, usually, the character will say what they are feeling. Sometimes they will have a dialogue with themselves to portray a internal conversation.

Character emotions during the scene will be conveyed not only by their dialogue but also by the tone they used in the audio recording.

For example,

when you watch a horror movie, you'll notice a dark room with eerie lighting. On the other hand, in an audio recording, the character will say "the room is so dark, it's so eerie ... I"m scared".
