Sound Map

During the Sound Spaces (Liverpool) project, Eashan and Pinky Raychaudhuri produced an iPad composition (titled “A Bundle of Laughs”) from field recordings they had made around the city. Working with Stefan Kazassoglou, they then relocated their manipulated recordings by giving them the sonic character of the places we had visited. This was achieved by convolving the manipulated recordings using the IRs of the sites we had visited, playing them back through the Kinicho’s ambisonic sound system (COSMOS), and recording the result onto personalisable audio greetings cards. Further, photographs Eashan and Simon had taken of the sites were used as images on the cards. Alongside this, Simon and John had experimented with visualisations of the city through layers of maps and using the locations visited to plot imaginary sound lines across the city. We presented these ideas together as a SoundMap initially as a map projected onto a table with the greetings cards placed on the relevant locations, and then at a public exhibition using using a printed map mounted onto a wooden board and placed onto a stand. Audio transducers were placed underneath various relevant locations of the map playing back sound relating to that place. Some of the sounds were also processed through the relevant IRs to create a convolution reverb effect.

SoundLines

An original inspiration for the Sound Spaces (Liverpool) project, was my proposal to explore the city’s ‘sound lines’ (“one part song-line, one part ley line”) – imagined sonic ley lines between different locations, and how they might create virtual connections between seemingly disparate places. During the course of the August SoundLines workshop, I devoted much attention to making a piece that embodied a ‘sound line’. The sonic component of this piece involved cross-fading between recordings made at one site in the city to recordings made at another. As the cross-fade took place the recordings were transformed by algorithms coded in Pure Data into more noisy, drone-like, pulsing or crackling forms of themselves. In this way, as the piece unfolded the listener was ‘transported’ between locations and in and out of more sonically abstracted forms. In this creative conceit, these more abstracted forms were imaginings of the hidden ‘sound lines’ connecting the two locations. A visual projection showed the relative locations of the sites, the lines connecting them, and the current position of the cross-fade against a background created by collaging historical maps of the city. For the public exhibition, I further developed the piece to work over a multi-channel loudspeaker system and five HD monitors.

GPS Traces

GPS tracker

During the Sound Spaces (Liverpool) project, as well as recording audio and visual material from our field visits, I collected GPS data using the iPhone application ‘Track’. Taking inspiration from the self-archivist Jacek Smolicki each day was ‘tracked’ and at the end of the day these traces were distilled into minimal lines, keeping only positioning data and ridding it of all other metadata. Each day was shown as a different image and simply presented as a black line on a white background. An ANS style synthesiser was built in Pure Data and used as a way of generating sound from the images. In this construction each pixel line related to a different oscillator. The gain of each oscillator was controlled by the grey value of each pixel. The image was scanned vertically and then changed to another day’s image at random.
