Jorge, In freeswitch you can set the resolution of a conference with different profiles in conference , 8k,16k,32k etc.. I have noticed the delay increases as you increase rate which makes sense as more data is sampled. <param name="rate" value="8000"/> In /autoload_configs/conference.conf.xml Regards, Stephen From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Jorge Núñez Sent: Wednesday, August 14, 2013 1:20 PM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] Mod_shout using with icecast Big delay Sorry but I am very new with freeswitch!!! what do you mean with 16K or how can I know with how can I configure that?

So Can anybody tell any other solution instead of webrtc and icecast to broadcast a conference in realtime without delay or maybe just a little bit of delay 1s or 2s? Thank you very much for your help Jorge 2013/8/15 Jeff Leung <jleung@v10networks.ca>

Icecast is known to have a relatively high latency for audio.

Anthony and just for test how can I reduce the latency? and thanks Michael for use webrtc Do I need to use Sipml5 or JSSIP o are there any othe way to use because I was trying to find some information about mod_html5 but I didn´t find

thanks

The alternative if you want in sync audio would be to use webrtc endpoints to listen.

Icecast is not designed for low-latency and realtime audio. Its designed for higher quality reliable audio. The servers and the client libs both use latency and buffering to guarantee this. There are some techniques to reduce the buffering on at least the FS side but then you will start getting skips and resets if you miss any packets.

This comes up all the time when people first try doing this. Either you need to just accept the delay since most people will not even know its there or use some other method.

You have to keep in mind that icecast itself has a fair bit of buffering involved with it and theres not a lot you can do about that

Yes it is!! because I have a live chat and other stuff working in real time. So the voice wont have a big delay respect the other stuff. I am using node,js and websockets for the html5 client thats why I want to use the audio tag instead a flash player or something else Thanks Jorge 2013/8/19 Anthony Minessale <anthony.minessale@gmail.com>

Is there a a real significance to it being 12 seconds of delay? The people listening will not know it. I am just wondering if there is a tangible problem with it or if its just obsession when listening to it in a test env.

Hi I am using mod_shout to send a conference call to icecast and hear it from a tag audio in html5 in realtime, but it has a big delay like 12 seconds. How can I reduce the latency of the audio sent from freeswitch or what can I do to improve this.

Regards
