The ACAM_64 acoustic camera produces real-time moving images showing sound sources in its field of view. It can be used to find, measure, track and record sources of sound.

It 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.

ACAM_64 is an 88 microphone array, and real-time beamformer. It can build a 3232 pixel image of sound sources in real-time, with adjustable frequency response within 20 Hz to 8 kHz.
Its massively parallel beamforming DSP allows the instrument to build each pixel concurrently with no missed sample.
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.
The ACAM_64 presents acoustic images, showing sound sources in the field of view of the instrument. But it does not show an optical image, so it is difficult to match acoustic hot zones with the actual pieces of equipment creating the noise. The optical camera kit captures the scene in parallel to ACAM_64, and Instrument Manager presents the optical image superimposed onto the acoustic image. The videos below show how that optical image facilitates the interpretation of the acoustic image.
A complete Windows application is provided to operate the camera, view and record images of the sound source.
