Live audio streaming over wifi network

What I would like to know, is it possible to stream live audio over a wifi network.

PC A records a stream from a mic and then simultaneously broadcasts that same stream live over the entire wifi network, sorta like a radio station only on a much smaller and simpler scale.

Is this possible?

Yeah you can use pulseaudio for that but I'm guessing it might saturate your wifi link.
Or you can use mpd and stream it using icecast.

mpd also has a built in http output now, no icecast needed.  if you decide to go that route...

Re: Live audio streaming over wifi network

Sorry for the barrage of questions, but I'm a n00b when it comes to this.

What client can one then use on a Windows 7 netbook to receive the broadcast?

Sorry, should have mentioned I'm looking at using icecast.

Re: Live audio streaming over wifi network

Maybe you should try searching some? I did a search for icecast windows and found this site:
http://www.icecast.org/3rdparty.php

I'd use Foobar2000 as my Windows client, although I have never used Icecast so I'm not sure how it works. Foobar2000 is a great application in any case, so give it a try.

I was at that exact link looking at Source clients, must have had eye patches on not seeing the next group was media players to use....

Thanks.

Re: Live audio streaming over wifi network

i use evil player when i connect from windows (not sure if there's a version for 7 yet though).  it's insanely light, runs in tray, opens instantly, and i only use it to load my stream.  it plays great whether i encode the stream with vorbis or lame.

Re: Live audio streaming over wifi network

It seems like I'm missing something with icecast. If I understand it correctly then you can only play an existing media file, no real time live broadcasting?

I have finished setting it up and can listen in over the network, but I need real time broadcasting. Is there a way to do this in icecast or should I look at something else.

SYNOPSIS:
While someone is talking over the mic the server records the stream with Audacity for editing later on. The problem is that I want this stream to be simultaneously streamed live to another PC so that people next door to the meeting can hear it real time, no delays. A few seconds delay is not critical, but I cannot record and hour long session and then broadcast it, it has to be real time.

To complicate things, there is no internet available, we are in the middle of nowhere on a secluded convention centre, so that is why it seemed to me like the easiest would be to broadcast via WIFI.

Re: Live audio streaming over wifi network

maybe record into a fifo and play the fifo via icecast? a socket may work as well.

though, with this approach you might even want to look into netcat.

edit, forget netcat... dumb windows clients...

Re: Live audio streaming over wifi network

It seems ices2 can do what I want, but I have a bit of trouble configuring the config since there are very little documentation on it. If someone here are proficient with ices2, give me a shout or please post you config so that I can have a look at it please.

I get ices2 to run without any erros but I get no sound on the other PC.
