Sonic Drift is a workshop and action about exploring a city through
sound and live audio streaming. We appropriate psychogeography and the
Situationists Dérive actions as a starting point, and combine these
tools with the contemporary tools of locative art; geolocation, mobile
networks and ubiquitous computing.
We will make live collaborative soundscapes by streaming audio from
the muliple "agents" engaging in their individual psychogeoacoustic
city survey, back to a central location. These audio streams
or "streamscapes" shall combine to create a portrait of the city at
one time from multiple perspectives.
Sonic Drifts is a project of the Locative Music Ensemble and the
workshop is led by composer and network artist Rob Canning.
The workshop will be in two parts. In the first part we will look at
the technological tools we will use in the drift and in the second
part we will discuss and devise stragies for the drift.
workshop: part one
Experience with computers, coding, streaming is not essential, this is
more of a taster demo session.
This will be an overview of tools you need to make live audio streams, both from a fixed location and from mobile locations using 3G/HSPA mobile networks.
There will be a short introduction to some streaming server and client software such as Icecast, VLC and Liquidsoap followed by a look at battery powered portable setups using the embedded linux Raspberry Pi computer along side batterypacks, high quality audio interfaces and tethered data links.
workshop: preparing to drift
Having learnt how to assemble the mobile streaming rig, we will as a
group embark on a sonic exploration of the city, each with our own
streaming rig broadcasting the sounds we create/encounter live back to
the "base". The base shall comprise a multispeaker surround setup with
a pair of speakers relaying the sounds from the outside back
inside. Four "sonic drifters" each will transmit stereo singals
resulting in an 8-channel surround sound soundscape, each stream
hearing the same city at the same time but from the different
perspectives of the drifters.
In the second part of the workshop we can discuss how we
may want to execute the drift and devise a course of action.
The exact time of the drift is TBC but perhaps somwhere around
~7.30PM. We shall drift for as long as the batteries will allow
~1.5hrs or a timescale we decide on together in the workshop
discussion. We may doing two shorter drifts, one to make a live
8-channel streamscape and maybe another to record and document the
After the drift we will return to the contemporary music centre where
we can informally continue to disucss a mixture of the technological,
social and aesthic aspects of the sonic drift. This part will also be
open to the public to engage with as part of CMC's culture night 2013.
It will be very informal however with the public themselves drifting
between rooms where different composers will be working on and
presenting different projects. It is not a formal concert or
performance but more like an open studio... with some wine.
We can also use this time to gather recordings and project a
mutichannel version of what we did during the day to project through
the multichannel speaker system.
what to bring
If you have a mobile phone with a data plan, bring that, and a cable
to plug it into the USB of a computer. Bring a laptop if you have
one. Bring a zoom audio recorder if you have one. I have a few spare
bits and pieces. So dont worry about this if you dont have any of the
