I got an interesting phone call enquiry tonight. Protest meeting...but the organisers want the speech relayed from the centre of the town down to a gathering area approximately 0.75 miles away. Rather than running a cable (which would involve crossing a four lane road, and a river, I am thinking of using an internet link for the audio. Its speech only, so it doesnt need to be the upmost quality.

Could you do this using JACK? or Shoutcast. I know it can be done....but looking some pointers on how to do this?

[RYAN LOUDMUSIC JENKINS]

Ships ahoy matey!  Pull out the eye patch and wooden leg and see if you can figure out the easiest way to get the audio there.

[Bob Leonard]

Done all the time. Look to Microsoft my son and be saved.

I use Shoutcast all the time for radio remotes, but you need to set up an account with someone hosting Shoutcast servers.  They are not expensive, but it does take time to set up.

On the other hand, Nicecast for Mac allows you to use your Mac as its own server.  You can just log in to the Mac itself as "local host".
I do not often do this, but it is theoretically possible depending on how clever and persistent you are with Macs.

[Ned Ward]

A Danley Jericho JH90 would get the sound there...

Yea I have been trying Nicecast...seem a simple enough piece of kit. Can get it to work fine when I'm on the same network...having a small bit of bother when the two devices are on different networks though...we will work through it

haha i don't think the residents of the town would appreciate 150dB-SPL been blasted at them

If you know anyone who's running a server and has space, they can set up to host for you on Shoutcast.  I use my Shoutcast server and feed it from Nicecast/Icecast on a Mac.  It works better than the PC setup (for me, anyhow) and is more flexible.  Little things like setting the frequency can be done on the Mac but not on the free setup available for PC.

Good luck.

Just out of curiosity, how does your shoutcast setup audio quality compare to an ISDN line?

This, and won't ISDN be more stable... We got crappy broadband here in South Africa so if you want something like this ISDN is the only option...

[Mike Sullivan]

You have a variety of internet-based options...Shoutcast works, but there may be a delay, something like 30-60 seconds.  You could use VoIP such as Skype, or a voice chat software such as Teamspeak or Ventrilo.  All of them are free.  Skype just needs two accounts on the same call to work, while Ventrilo and Teamspeak require a separate "server" software to run (free up to a certain amount of users, so won't cost you anything), however if the internet connection is slow or bad, you may have dropouts.  Just my two cents.

I have got it working using a shoutcast server....streaming from nicecast on my mac as Dick suggested. About 20 second delay so its not too bad. Hoping to use wifi so it should be pretty stable. If the wifi doesnt work out I can use 3g dongles

[Lyle Williams]

Watch out if you build a system for a protest based on 3G data as a link.  Something that works well in a test run may not work so well when 1000 people show up at the site with their smartphones.

Something based on a mobile phone call is safer, but still not 100% reliable.  Get the call open some time before you need it, and don't hang up until the event is over.

This might also work, line in for the phone should be a possibility and then line out on the other side, could make for interesting wiring but most phones can accept a mic/line input these days, line output is simple enough...

[Riley Casey]

Telephone hybrid, the old stand by.  Telos Model One or equivalent, easily rented, safe and reliable.

You'll find the latency varies for myriad "whatever" reasons.  I've experienced near zero to slightly upward of 15 seconds.  Funny thing is I can have two computers side-by-side logged in to the same server, each experiencing different latency.

You can "back up" your stream by logging in to the Shoutcast server using two or more different players.  Mute the ones you're not using and if you have any trouble with, say, WMP, you can just un-mute WinAmp or QT...or whatever you're using to get the stream.

Beware of Saturday nights, though.  What will work flawlessly the rest of the week can go to pot instantly if you have a nearby high-rise or project housing all watching movies, Skyping with the "homeland" or downloading porn.  Packet loss will start to give you fits.  But for voice only (where latency is not critical) you can increase your buffer size

THIS. The park I work at has a Verizon tower literally 50 feet off the property line, works great most of the time, no dead zones on the park, etc... But any day there's a concert (20,000-30,000 people there instead of 5,000 to 10,000) your chances of getting a 3G/4G OR voice connection drop amazingly. And that was with a tower specifically designed to handle high volume at the location, not a standard cell site in the middle of a city where cells are usually closer together and have to hold fewer connections at a time.

Point is, don't rely on the mobile connections unless you can test them under the same conditions they'll be operating under, and even then don't think it is foolproof. I personally would go the landline hybrid route, honestly.

[Tim McCulloch]

Yes, yes, yes.  Lyle, Dick, Riley and Chris speak the truth.

[Lyle Williams]

... Of course is does depend on event details.  If you are expecting 100 people don't go overboard.  :-)
