Broadcast Audiostream To Multiple Devices

I am using android AudioStream to communicate between 2 android devices on wifi, both ways. Is there any way to broadcast an audio message on multiple devices, in the same time ?

Solution 1:

I think the simplest way is to stream all devices using AudioGroup, you just need to create separate AudioStream for each clients and join them to one AudioGroup. That is it.

AudioGroup audio = new AudioGroup();
audio.setMode(AudioGroup.MODE_NORMAL);

AudioStream stream1 = new AudioStream(yourLocalIP);
stream1.setCodec(AudioCodec.PCMU);
stream1.setMode(RtpStream.MODE_SEND_ONLY);
stream1.associate(firstClientIP, anyport);
stream1.join(audio);

AudioStream stream2 = new AudioStream(yourLocalIP);
stream2.setCodec(AudioCodec.PCMU);
stream2.setMode(RtpStream.MODE_SEND_ONLY);
stream2.associate(secondClientIP, anyport);
stream2.join(audio);
