ACAM_64 is an 8×8 microphone array, and real-time beamformer.
It can build a 32×32 pixel image of sound sources in real-time, with adjustable frequency response within 20 Hz to 8 kHz.
An acoustic camera produces an image where the intensity of each pixel represents the amplitude of
acoustic waves coming from the corresponding direction.
This is akin to an optical camera producing an image where each pixel
represents the intensity of light coming from the corresponding direction.
The instrument can be controlled, and the images can be retrieved using an open protocol based on virtual Com port.
That open protocol can be used on any platform that has a generic USB CDC driver.
That includes Windows, Linux and Mac-OS.
The instrument can stream audio to the host platform through a USB-Audio interface.
Through that interface the instrument is seen by the host as a USB microphone. That audio signal is the output of the beamformer
and can be steered digitally to any azimuth and elevation in the field of view of the camera.
Using the provided Windows application, the beamformer can even track any acoustic source in the field of view.
That USB-Audio interface works on any platform that has a generic USB-Audio driver. That includes Windows, Linux and Mac-OS.
A complete Windows application is provided to operate the camera, view and record images of the sound source.
