Methods, products, apparatuses, and systems may provide at least multiplexed audio for a plurality of conferences. A conference attendee may simultaneously listen to the plurality of conferences via the multiplexed audio. Audio corresponding only to a respective conference of the plurality of conferences may be provided to another conference attendee having access to the respective conference. The multiplexed audio may be blocked from one or more other attendees. In addition, a conference operation may be implemented at any time to add a conference, delete a conference, select a subset of conferences, and/or rejoin conferences.
