[Freeswitch-users] How to mix audio in FreeSWITCH

Tue Oct 30 20:39:15 MSK 2012

Dude, look very hard at your code. All the API commands you are using are Async. You start the file playing, and right away you stop it, and then hangup the channel "sesison.hangup()".   

Why are you stopping the displace right away. If you want the whole thing to keep going, till it's done, then don't stop it, and don't hangup the channel. Maybe you should change the "session.hangup" to "session.execute("park")?

Hi Michael,  

I create a js script as follow:  
session.answer()  
while (session.ready())  
{    
apiExecute("uuid_displace", session.uuid + " start /opt/freeswitch/sounds/welcome.wav 60 mux");  
apiExecute("uuid_displae", session.uuid + " stop /opt/freeswitch/sounds/welcome.wav");  
session.hangup()  
}  
When I make a new call, script run normal but I do not see anything (the call hangup immediately) and I don't know How I can save "mux audio" to new file? Please guide me.  

Brs,  
Khue

  You might also try uuid_displace API with the "mux" option, although I kind of like the idea of getting a group of uninhibited users all in a conference room singing "Love Shack" by the B52's.

  Hi,  

You should try using "sox" if there is nothing you've found in freeswitch. Execute a system sox command and input the two recordings. Later the mixed audio can be played back to user.  

Another approach can be to use a conference bridge in which a local channel and the incoming caller are bridged and the conference is recorded. The recorded conference can be played back or used as well.
