Manage audio source of parallel conference

Hi to all. I wanted to ask if it was possible to manage the audio source of x conferences in parallel into one (which are obviously on the same server), here is an example:
there is a room in which a topic is discussed in a certain language in this url:
In the same time there are 3 conference that are running in parallel in the same domain but in different room :

    in which a translator speaks in his own language and is the only partecipant of this room.
    Is possible to redirect only the audio_source of these rooms inside one room ( in this case in ) and gives to the user the chance to choose what language listen by using buttons?

Thanks to the availability, best regards.
