1. xlr - first real audio experiments
2. xchange open channel
3. mobile broadcasting (from train and boat)


In 1997 the internet was moving to a new dimension as its capacity was rapidly expanding. It was possible now better to explore the advantages of Real Audio technology 
(emerged in 1995) and to experiment with real-time net audio streams.

* (first) experiments with live streaming - XLR project/1997

One of the first and most interesting experiments with live real time audio on the net was the project "XLR" (Xtended Live Radio) initiated by media artists and independent 
radio people from Berlin and Ljubljana, in summer 1997. 

XLR - XTENDED LIVE RADIO (project) (borut's report+archive) (moni & ulf's text)

XLR was a 14 days after-the-midnight net & fm (broad)casting project, from August 24th to September 5th 1997. 
There were two main concerns: live-web-radio and live-fm-radio. The first week of fm-live-radio was broadcasted from a studio at Radio Student, the second week from a 
public space, Kapelica Gallery, both in Ljubljana.

Initiators and organisers of XLR project:
Berlin: Ulf Freyhoff, Monika Glahn INTERFLUGS HdK and Dagmar Gabler 
Ljubljana: Marko Kosnik, EGON MARCH INSTITUTE, Borut Savski MINISTRY OF EXPERIMENT @ Radio Student Ljubljana

"Main subject of the XLR experimental radio & internet broadcast is the investigation into different ways of eXtending Live Radio. 
The basis of this investigation is the establishment of a temporary network between various independent production contexts in the area of former Yugoslavia as well as in 
different cities in Germany and hopefully throughout the world."
(from XLR concept)

>Monika Glahn & Ulf Freyhoff, media artists from Berlin, initiators of the project, wrote:

"We invited people from all over the world to participate and contribute, it took some days till contacts to other places started to work, so the first days we were doing the 
whole program ourselves. So we focused and improvised on subjects which were about what we were doing there, for example one day it was about feedback (this was the 
day when finally the line to berlin worked and we could work and play with a lot of internet-audio-feedbacks that night...)
Other subjects were real-time; machine and human languages; nothing, something, anything; sun ra .. and (of course) cyberpunk, cyberspace and cybereverything.
 During the two weeks we managed to successfully combine communication techniques of all available kinds (low-power fm-links, high-power radio-broadcast, telephone 
lines, one-way and two-way web casting on Internet).

General shape of the program was a kind of monologues, lectures or readings, discussions, music and experimental live-mix, interviews. The structure was a main program 
between midnight and 2 am, which we called 'main content area', then from 2 till 4 am mix/improvisation and from 4 am till 5.30 music (recreation). We then faded out with 
Dagmars Wusch, an ongoing story about the 'cyborgs' that she wrote during the time of the project and reflected the things that were happening during the broadcasts.

In parallel chat was running all the time, and people, who were not able to send sound, gave comments or participated that way and we read parts of this communication 
during the program too. There were even people from Australia, Tokio and New York participating."

XLR project was one of the first experiences in building up an open platform on the net for communication and collaborative broadcasts, connecting virtual and physical 
spaces, exchanging the ideas on-line via irc chat channels, creating the programme and audio content together with physically remote located participants. 

>From a call for participation for a special night's program:

"We are offering the platform we built on this evening to special projects and persons whose work in different ways does connect positions and ideas and puts strong 
efforts in opening and establishing spaces for creativity, exchange and discussion."


Half a year later after XLR project the other project on building up a platform for real-time audio experiments started. The project Xchange Open Channel is initiative of 
E-LAB and OZOne from Riga; it is still on going and open for everybody to join in. 

X-Open Channel is on-line every Tuesday night starting 21.00 CET during OZOne live net sessions or any other time when someone initiates it.
Meeting and co-ordination (of who, how, what and when will stream, or how will pick up what stream in order to create the loop) mostly is used IRC chat 
#xchange channel (or web java browser at

X-Open Channel started in the beginning of 1998 due to Xchange mailinglist that was established in December 1997 in order to exchange and distribute the information 
among alternative net-broadcasters. 
(Xchange mailinglist archive
X-Open Channel was initiated by Riga OZOne. The idea was to explore co-broadcasting possibilities. 
During X-Open Channel mostly of many interesting experiments we did without any preplanning - immediate realising of ideas together with other remote broadcasters was 
the way how we were trying to explore the acoustic cyberspace. 
The loop - created often by more then 3 remote net-casters from different parts of the world which do their different sound inputs - makes an inexperienced noise. Because 
of delays - up to 2-4 seconds, which real audio stream needs for buffering - audio inputs in such loops are creating multiple layers of looping sounds. The noise is reminding 
the chaos - but in the same time you can experience how it is creating the virtual space - the 'real' multi-dimensional acoustic environment.

3. MOBILE NET.BROADCASTINGS (form train and boat)

KITKAT - mobile broadcrasting from train
- broadcasting 'in' and 'from' (via mobile phone) the train 
(co-project by Radio Kit-Kat and radio OZOne/E-LAB and)

broadcasting via mobile phone to the internet:

'local' radio KitKat within the train:

Radio KitKat:
The project was intended and created as the sound intervention into the closed public space - the VTT train as well as a live netcast. It was carried out by the three 
collaborative partners Radio Kit-Kat (Peteris Kimelis, Kaspars Vanags, Sergejs Timofejevs) on board the train, mobile phone line (Baltcom GSM) +Internet connection 
provided by Radio Ozone and E-l@b (Rasa Smite & Raitis Smits, Janis Garancs). The broadcasting was an independent and self organised activity within VTT. 

REBOOT - mobile broadcasting from boat
a floating media art experiment & telematic club event, october 1999, 
boat with media artists traveled from Cologne to Amserdam
