[Ralph Hoyte posts] I am a Bristol-based poet, writer and producer of GPS-triggered locative media. I deal in the live voice – mine, or multi-voice set-ups, set, er, somewhere, somehow. I write, sometimes, ‘poetry’ (whatever that is), more often, ‘poem-scripts’, often heavily research/historically/cultural-historically-based. I deliver them live, or through ‘locative media for the smartphone’, or through any other means to hand (such as Raspberry Pi powered sculptures responding to user input through touch or light). I often work closely with Phill Phelps, coder and audio-engineer, on the technical aspects of such projects.
For step in stone I am working on a triptych of sound interventions which all feed off the same poemscript; SYNCLINE , ANTICLINE, AND PROCLINE.
SYNCLINE

come in numero 82 your time is up: the different bits of the autonomous megaphone assemblage
The poemscript is recorded (2 or 3 voices, probably my voice and 1 or 2 synthesized voices), placed on an SD card inserted into a mini-mp3 player circuit board, played back through a megaphone (it’s waterproof), whole thing driven by, essentially, a motorbike battery. There are 5 or 6 such autonomous assemblages. They are hung off the edges of the cliffs in ‘The Amphitheatre’. Each unit has a different ‘personality’. The SD card is loaded with poemtext, possibly ambient, and … silence. At any one time you get poemtext, ambient, or silence. Six of these doing that, each with its different personality, creates the soundwalk as you perambulate around the floor of the Amphitheatre (keeping well away from the walls!). I like serendipity. There will also be a nightwalk.

‘The Amphitheatre’ at Fairy Cave Quarry
ANTICLINE
A GPS-triggered soundwalk for the smartphone: ‘pools of sound’ are virtually placed along the ‘figure-of-eight’ walk around Westdown Quarry (think that man on the TV add who stumbled across a red circle on the ground: when he stepped into it, he heard music, when he stepped out of it, it stopped. Remove the red circle. That’s it) You download the app, go to Westdown and turn it on. When your phone encounters a pool of sound you’ll hear the audio for that ‘virtual red circle’ (and, no, it doesn’t need a network signal). Of course, it’s more elaborate than that ‘red circle’ scenario: you can make the audio in the soundpools do different things; you can also, interestingly, ‘stack-up’ the soundpools, or overlap them. Who knows what happens when you overlayer 3 zones?
PROCLINE

‘A haptic audio-device’ for the Canal & Rivers Trust
For starters, the word ‘procline’ doesn’t really exist (see, WordPress underlined it in red. It doesn’t exist), and, if it did, it’s not, unlike ‘syncline’ and ‘anticline’, a geological word. Never mind. Maybe I’ll rename them ‘syncline’, ‘synform’ and ‘syntax’. Whatever it’s called, PROCLINE is going to be a gallery-piece consisting of (probably) a geological specimen drawer thing with 3 drawers. When you pull out Drawer 1, audio channel 1 is activated; ditto 2, ditto 3. What you hear of the common poemscript depends on how many drawers you’ve pulled out/pushed back in, and in what order. To add another layer of serendipity,we may programme it so the audio-files associated with each drawer are chosen by the mini-computer driving the whole thing. In the drawers may be … stuff, resonating with the quarries. So it’s visual and tactile and user-directed.
