bx - bROADCAST BOx

so, as announced, here's the first result from recent bricolage works... : the bx!
it's a mobile radio device for entering, exploring and playing with different media spaces more or less simultaneously, at almost any location.

some facts and figures:

• a 0-15W stereo FM transmitter can enter the whole FM radio band, 88-108MHz
• the sender is connected to a small USB 5channel mixer/soundcard connected to an eee pc, equipped with various audio and streaming software.
• the main mix (2 stereo lines, 1 mic line, and computer's audio sum) can be broadcasted to FM and a (e.g. radio aporee) streaming server at the same time (wifi or 3G network given).
• optionally, the telephone network and radio aporee mobile interfaces (app etc.) can mix into the stream/broadcast too. things to do here...
• the unit is powered by a 10Ah battery (+ netbook accu) at 5V/USB and 12V, optionally supported by a 10W solar charching unit if weather conditions are fine. that should give some hours of independant outdoor operation...
• the only thing that doesn't fit into the box for now is the FM antenna. working on...

next step is to fine tune the box, set audio and signal levels, and test its range in various conditions (antenna on the roof, in the field, on a hill, etc.). a set of wireless microphones would fit the concept perfectly... more to come, stay tuned...

radio activity

I've recently focussed again on the radio aspects of radio aporee. within the last years, it has continuously played recordings from its global soundmap project. however, it has now turned into an adaptive/reactive/sensorial stream that may (or may not...) recognise and react to events and acivity, e.g. new sound uploads, listeners tuning in, mobile app activity, live input, phone calls, emails etc. it's an ongoing experiment to explore extended concepts and practises related to sound/art and radio, tune in with your favourite player or open on the web.

not everything is working yet, but while listening for many hours during recent weeks, i quite often had the exciting experience of what i'd call radio space:  ephemeral sonic narratives formed by chance and whatever activities, a connectivity cross media and geography, and an intriguing sense of presence and place. of course, all that wouldn't be possible without the many great contributions to the aporee soundmap.

Further, within these radio acticities, i've started working on a piece called bx, broadcast box. it's a portable box containing an 15W FM stereo transmitter, a small 5-channel USB mixer/soundcard, optionally a computer with WIFI and 3G networking, and an energy unit consisting of a 10 or 20W solar panel, control unit and a 12V/10Ah battery for powering the whole thing. the bx will be able to
send, receive and mix between the internet and FM airwaves from any location where a network is available. currently i'm sorting the parts, more on that soon, stay tuned...

radio aporee ::: mariborMaps

Within the last months, Patrick McGinley and I have worked on an soundmap of Maribor, Slovenia, during the European Capital of Culture 2012 events, in the frame of the project AS WE SPEAK, by Goethe Institut Ljubljana. The results are quite nice, also thanks to the participation of local artists Petra Kapš, Ana Pečar and Andrej Hrvatin.  Listen to the recordings on the radio aporee ::: maps website.

One of my favourite spots is the flour mill near main station. When in action, its hypnotic sounds can be heard all over the place, for example in Mestni park (recordings taken during a soccer match in the nearby stadium). Surprisingly, most of the Maribor people have never recognized it.

Patrick, Petra and Andrej at work at a small chapel in St.Urban, in the hills near Maribor. Patrick recorded rain in the gutter with his great DIY contact mics.


During the MariborMaps project development, nearly 200 recordings (and still growing) have been gathered from the city and its surroundings. The sound installation MariborMaps for mobiles is a projection of the overall soundmap into an area located around Trg Leona Stuklja. Relative directions are kept as much as possible, so listeners may explore a selection of sounds from Maribor within a comfortable walking distance, from Vinarje to Tezno, and from Mariborski Otok to Melje. The installation is accessible via the radio aporee app for Android phones and will be available at least until the end of 2012. See also MariborMaps for mobiles.

Global 4'33"

We've recently received an invitation from the World Listening Project, to join a special birthday party.

So, here at radio aporee Berlin, we've celebrated John Cage's 100th birthday with a small performance of 4'33" for 2 players (Henrik Schröder, Udo Noll), 2 cymbals and 2 tuning forks, along with a screening of the film "4 american composers. vol. 1: John Cage" directed by Peter Greenaway in 1983.

Listen to a recording of the performance

In order to extend our audience, i've set up my mobile pirate radio station. the event was broadcasted on the frequency of a pretty shitty station here in Berlin... so we've probably reached quite a lot of listeners...). Here you see the DIY antenna hooked up outside of the space.

Henrik Schröder did a recording of the broadcast as it could be heard with a transistor radio out in the streets, along with some surounding sounds.

D-Radio-Ortung ::: 50 Aktenkilometer ::: a walk-in Stasi radio play

the cooperation of Deutschlandradio Kultur and radio aporee continues with a project of german artist collective RIMINI PROTOKOLL. the project starts on May 17, 2011.

Rimini Protokoll haul the Stasi files out of the archives and into the
city's present: About a hundred people in Berlin's Mitte district are
surveyed and for the microphone recollect or reconstruct observations of
the sites where the misdeeds were perpetrated. A strange picture-puzzle
is created for the users, who have the everyday life familiar to us now
in view and original recordings from that time in their ears.

Tuned City Tallinn - Sonic Landmarks: a sonic path through Tallinn

The radio aporee workshop in Tallinn, April 2011, introduces the new project miniatures for mobiles, a platform for the creation of space-based audio works. The
workshop consists of lectures about the conceptual and technical background, and practical exercises as well as sonic explorations within the Tallinn area. The workshop aims to instruct participants in how to use the authoring tools provided by radio aporee, and ideally would result in an audible miniature for mobile media, to experience by listeners now and in future.
