Is it possible to have several audio streams? (for example different languages)
OnSync is not designed for this particular purpose but you could broadcast via two different audio streams simultaneously and your audience would then be able to mute the one they don’t want to listen to. You can invite the second speaker as a moderator. It is possible to have multiple moderators in a meeting. Alternatively you could open separate accounts, one for each language, and then send your customers to the particular language room they are interested in. Whichever method you choose, you would have to use a separate computer for each mic and of course this does not have to be limited to two streams, it can be as many as you want.
