The Fletcher Machine is being developed by musicians and sound engineers with a high degree of knowledge and concern for the needs in real life situations. It benefits from a genuine development where sound spatialization relies on both amplitude and delay differences. Signals that are send to the loudspeakers are calculated from the objects point of view, ensuring the best spatial coherence for the listeners. The Fletcher Machine offers a complete set of OSC (Open Sound Control) and MIDI integrations, so it can be externally controlled by a mixing desk using a dedicated plugin (under development), Real Time Tracking System, or any other interface using these protocols.
