There are multiple ways broadcasting from remote locations (with or without somebody being in the studio).
In any case preparation in advance and good timing is very necessary. Do not underestimate the amount of testing, coordination and communication during a live production. You can save yourself, your guests and the people doing the previous broadcast a lot of nerves if everything is well prepared and tested.
While establishing the remote connection and during your live broadcast please call into the studio using a (separate) cellphone to +49 (0)421 9595 1213 (this is our studio desk phone, not the on-air number.)
Remember that method 1 and 2 have a 5 – 30 seconds delay. That is alright in most situations, and makes sure the stream does not cut off. Communicate with your correspondent in the studio to agree on how the handover to the remote location and back to the studio is happening. (e.g. counting in form 10 to 1 works well, announcing "back to the studio" or similar on air, and agreeing on a precise clock-time for the cast to end.)
Enjoy the ride!
The easiest way to broadcast (form anywhere) on Angrezi is to do establish a direct stream to our server. All you need is a good internet connection (wired if possible), a computer and possibly an external sound card. (You can also use the mobile studio or another hardware streamer / encoder if you have it.)
You can use the free and open-source software Butt ("broadcast using this tool") on Windows, Mac or Linux to connect, stream and record. You can also use other software that supports the Icecast protocol (and works with Liquidsoap).
Settings▸ in Butt to set up the server connection (main tab) and sound input (audio tab).
Add a new server and Connect to our streaming server with the following settings in Butt:
Name: choose a name for this connection (e.g.
Angrezi Live Show)
8002 (Alternative port if your firewall is blocking
no SSL (nothing to do)
IceCast User: <your username> (or
Passwort: <your password>
As soon as you have your settings saved you can start streaming using the Play Button **
▸ in the main window. The status should switch to
connecting... and then to
stream time XX:XX:XX. Use the red recording button
● to also do a local recording**. (You can enable automatic recording in the settings window.)
You can select your audio input (soundcard or virtual soundcard) as Audio Device in the audio tab. The samplerate must match your soundcard. Some cards support multiple sample rates. Select 44110 Hz if you can, that is what the Angrezi stream uses as well. Please stream with MP3 320 kbit/s (Stereo). Remember that you have to record locally: 320 kbit/s MP3 or uncompressed WAV is recommenced.
This is the almost same setup (and use case) as before. The signal does not go directly to the stream though, but is routed into an analog-in on the studio mixer. (Note: Nonetheless you will have a 5-15 second delay.)
We did add a custom Icecast-like harbor with
Liquidsoap, which outputs directly to the studio mixer. Remote locations can easily be integrated into a live programme broadcasted (primarily) form the studio.
Connect to our Icecast server with the following settings using Butt (see above):
Passwort: (ask the producer or engineer or tech crew)
Name: choose a name for this connection (e.g.
Please stream with 192 kbit/s. Remember that you have to record locally: 320 kbit/s MP3 or uncompressed WAV is recommenced.
You can only connect if this harbor is currently not in use.
As always: Please test your setup in advance! Soundcards, hardware, sampling rates and internet connections might be different and can (or will) cause trouble. Preferably do a test run at least a day before you want to go on air.
We use a IP-based – yes, no more ISDN, wow! ;) - voice bridge to connect remote guests to the studio / stream. This setup can be used to do productions from multiple locations with two or more participants / locations.
We have used two protocols / providers so far:
__Now __by Source Elements (not used in production so far)
Both protocols use peer-to-peer Audio over IP (e.g. SIP with Opus), and require only a decent internet connection.
Download and install Studio Link on your computer. The software will run as a service (in the background when started) and controlled through your web browser. Your web browser will open automatically when you start the service.
You will find a step-by-step overview (in German) and further on Studio Links website. This explanation is referring to the standalone version of Studio Link. A DAW plug-in version available as well.
As soon as the service is running you can select your audio interface and start a connection ("call"). You need a partner ID to call to. Ask the engineer to give you Angrezi's partner ID in advance. (We currently don't have a fixed / named parent ID.)
Studio Link might be running on the studio mac already. You can access the web interface at http://127.0.0.1:58736/. Otherwise start it.
Usually studio link is routed on the same channels as the telephone system is. (If your show want to take regular phone call-ins as well, this must be changed.)
Send your partner ID to the partners. (We currently don't have a fixed / named parent ID.)
Requirements: Windows, Mac or Linux PC, a good internet connection (1 mbit/s up and down is plenty), and the Chrome or Chromium browser (not Firefox, Safari, or otherwise, sorry!)
Connect at to Source Elements at https://now.source-elements.com/#!/guest
ACCOUNT TO CONNECT WITH: radioangrezi
PASSKEY provided by our producer / host in advance.
You should be good to go! (Please test everything before you are on air!)
Visit Source Elements in the Browser (see controller / bookmarks bar). Everything should be preconfigured.
