c# – AudioUnit IOS Play A number of audiobuffers in similar time

Can we play a couple of sound on the similar time by the output audiounit?
I’m engaged on a voice chat software and nearly reached the final stage, however I’m on the lookout for a option to hear a couple of individual on the similar time, however I have no idea the place to look… any assist to listen to extra then one at similar time,
i exploit udp ship array bytes convert to AudioBuffer..
and making an attempt to resize audiobuffers so as to add extra knowledge uncooked from 2 array bytes acquired from server however did not work as effectively, one thing robotic nostril occur…
