Acoustic Measurement Microphone Array and Robot (AMMAR)

The Acoustic Measurement Microphone Array and Robot (AMMAR) is a specially-designed 72-element audio sampling system with two distinct array structures:

Emission elements may be mounted on a numerically control rotary stage. The rotary stage may turn infinitely with a resolution of 7 arc minutes.

All 72 elements may be sampled simultaneously at 48 kHz. The array can be extended to 128 elements by simply adding additional mics, pre-amps, and digital converters.

Emitters can be driven with computer-generated signals for closed-loop measurements, or independently for open-loop measurements.
