In 2011 Ralph Hoyte, Marc Yeats, Phill Phelps founded the artistic partnership Satsymph LLP (Limited Liability Partnership). Satsymph work together, separately or with invited collaborators to create, produce and distribute 'interactive mobile immersive media soundscapes': sound you experience in specific realworld locations - not in a concert hall, not streamed or online: in specifically designated locations.


Imagine 'a parallel soundworld' normally invisible and unhearable stretching out all around, above and below you, and the only way to access it is through that magic device we all nowadays carry: your smartphone.


What strange creations inhabit 'the soundpools' in this parallel universe? Perhaps a contemporary classical music/contemporary poetry fusion The Temple of Hermes. Perhaps a series of walks along the South Dorset Ridgeway ('ware the Ooser!). Perhaps you may care to eavesdrop on the conversations of the Romantic poets as they stroll, argue, discuss, eat and drink and create Romantic poetry across the Quantock Hills of Somerset in 1798? Or, in darker mood, wouldst thou care to 'Romance the Gibbet'? Your smartphone is the portal to all these experiences created, produced and published by Satsymph.

Satsymph The Temple of Hermes (Marc Yeats, contemporary classical music, Ralph Hoyte, poetry, Phill Phelps, coding and audio-engineering) interactive spatial audio soundscape on a theme of Hermes, Greek messenger of the gods and all-round rascal (trickster god) created for Hamworthy Park, Poole, Dorset. NOTE: film only; not yet released, waiting on BCP Council say-so due to Covid19


Romancing the Gibbet: a located app produced with the University of the West of England Regional History Centre placing authentic historical content about the notorious crime-scene executions (hangings and gibbettings) of the 18th/19th century in the places these executions took place.


Immersive Avebury: not actually 'mobile immersive media': this is a VR simulation of Avebury 3,500 years ago. Satsymph developed the sound environment. A partnership between Bournemouth University, Daden Ltd & Satsymph (AHRC: Arts & Humanities Research Council, EPSRC: Engineering and Physical Sciences Research Council):


1831 RIOT! The ReMake: 1831 Riot! was the world's first immersive audio-play. Set on Queen Square, Bristol, this ground-breaking work re-imagines the three days of the 1831 Bristol Reform Riots when the people rose up against authority and for reform.


Land Bone and Stone : We have produced three soundscape apps (LBS1, LBS2, and LBS3) set in the stunning South Dorset Ridgeway area, cited as one of Europe’s finest ancient ceremonial landscapes with its thousands of prehistoric monuments. The landscape is full of stories and sounds. These apps help you discover them.


The House on the Strand - experimental GPS trail based on Daphne Du Maurier's novel



Apologies for the mouthful! This simply means Satsymph layer audio over realworld locations and you get to hear the audio by downloading an app to your smartphone, then going 'on location' and moving around in this augmented soundworld.


Imagine a landscape layered over with 'soundpools' you can't see - but your phone can! The 'soundpools' look like the colourful 'blobs' or shapes above: they can be any shape, not just round. You download the app for that specific experience, go to the designated location, then you - you are the blue arrow - can see where the soundpools are on your screen. Go find! Go find out what happens when you find one!


Spoiler: what you hear in a soundpool depends on what you do: face one way, get one sonic experience; face the other, get another. Hold your phone up to the sky, hear the spheres sublime; hold it down, Dante's inferno. Walk slowly, get one sonic response; walk fast, get another: these are just some of interactivity Satsymph can build.


It's a new sonic experience: you change the experience by what you DO!
