Arphield Recordings is a project documenting impromptu arphid sound performance produced by people scanning their oysters cards in the daily routine of access control to the london tube stations.

The methodology of field recordings (documentation of site-specific soundscapes through audio recording equipment) is, in this case, focused on the sampling of sounds produced by the use of arphid (rfid) technology (cards and readers) complemented by digital processing involving sampling and synthesis from the source, speculating on the ad infinitum convergence of arphid tags and readers into an endless symphony of sound surveillance and compliance.

The project started with the idea for an arphid mob, inviting friends to join me at a designated tube station for a semi-coreographed sound jam using our oyster cards. The main question was ‘when and where’ as a major impediment would always be the heavy security at all the gates. It was decided I would do some observation and this would eventually indicate the best timing and location for our arphid mob. Observing the familiar tube’s access control gates, initially with no equipment and later with a camcorder, I realised that people were already engaging in impromptu sound performances. My documentation led me to discern varied patterns and even participatory scores, with mass arphid soundscapes punctuated by silences, glitches and cracks in the system, all warped up in a circadian rhythm of work-rush hours.

The first arphield recordings – documenting the impromptu sound performance of people moving through the London tube access control gates were done in Brixton, Kings Cross and Caledonian Road tube stations during march 2006 for the TAGGED one day event at SPACE Media Arts (NodeLondon March 2006), when cds with the tracks and locational tags were distributed.

The second arphield recordings- the stockwell sound/jam memorial happened on Saturday 10th of June 2006 when people in london were invited to gather in the Stokwell tube station and scan their oyster card for 30second sync periods accompanied by a podcast of pre-recorded oyster beep tracks.

The project remains open to contributions. One way of doing this is downloading the arphield recordings and visiting the station gates with the sounds on a portable music player to experience a mix of live and prerecorded oyster beeps.

Another way of participating is by contributing arphield recordings from a tube station access control gate. You can do this by opening an odeo.com account and uploading your recordings , tagging them as arphieldRecording followed by the number unique to your oyster card (as in arphieldRecordings-0503266130-03)
