What would be good alternatives that could replace the word "audience?" Also, what does the prefix "audi-" mean?

Some good replacements for "audience" are "spectators," "viewers," and "crowd." Also, the prefix "audi-" means hearing, listening, or sound. Ex: The audio range of the car is quite extensive. Ex: The movie's viewers seemed to have good reviews of it. Ex: Many spectators of the show were upset by the ending. Ex: The crowd was huge at the concert!
