Voices that surround the listener

It is our goal with On a Theme of Hermes to give the impression of an immersive aural experience. Part of our technique for achieving this is to apply simple spatialisation to the audio 'modules' that are seeded in the GPS landscape. 

A sound source heard in a space such as a simple room (see diagram below) emits sound energy in all directions. Surfaces in the room (walls, ceiling, furniture, etc) reflect the sound energy but they also absorb a little energy too. The air between source and listener absorbs sound energy too: when the listener is located far from a source, they will hear less of the direct sound and more of the reflected sound.

All of the raw material for the Hermes audio modules were recorded in an extremely 'dry' acoustic environment - with the microphone placed in a room with plenty of sound absorbing materials surrounding the performers (voice artists and instrumentalist). This enables us to simulate reflected sound with reverberation plugins - allowing us almost complete control over the acoustic quality of the final modules (i.e. the blend between direct and simulated reflections).

For some of the voice audio modules, we have experimented with the idea of moving sound sources - three voices moving around the listener in 'orbits' (see diagram below). 

As I said before, the three voice artists were recorded statically - but with careful processing the illusion of three moving speakers can be created.

I am running short of time so I will edit this post with more details shortly - in the mean time; here are the screenshots I have taken to show my technique for processing three voices to simulate 'orbits'.
