Field Synthesis creates Ambisonics channels without encoders. Every component is created as an individual signal, focusing on slightly correlated signals. Variations in phase and amplitude When passed to a decoder, their interaction

Example: A 3rd Order Composition

The fixed media composition Villeurbanne is entirely based on Ambisonics field synthesis:

Different layers are generated with different Ambisonics orders: first order for the analog synths, third order for the high-frequency hisses.

Synth Part

Instead of using digitally created signals, multiple analog synth layers are used to create a constantly cnanging FOA sound filed. With only slight detuned oscillators.
