Audioscenic (UK) approached me to design and build a custom 4-axis CNC motion platform for evaluating their spacial audio technologies. 

The project drew on my 10+ years of expertise in motion platform design, signal processing and robotics for research applications. 

The resulting system enabled automated, repeatable 4D positioning of measurement microphones, mounted in a dummy head, across the X, Y, and Z axes, with an additional rotational axis for head orientation.

Audioscenic developed Amphi, their spatial audio system which large electronics manufactures (including Dell, Acer and Razor) incorporate into everyday devices—like laptops, soundbars, and monitors to create a 3D soundfield without rear speakers or headphones.

They use a custom AI position sensing system to track the listener then use advanced audio techniques like beam-forming and cross-talk cancellation to create an immersive 3D sound-field which surrounds the listener.

I designed a platform to precisely position measurement microphones mounted in a dummy head in all linear axis (X, Y & Z) and an angle axis for turning the head. The equipment was designed to be silent when static to allow audio measurements and featured laser guidance to make aligning test items easy when setting up experiments. I also developed a Python API to control the hardware to make it easy and fast for Audioscenic’s development team to integrate the equipment into their measurement workflows.
