Microphone Arrays
One of the most important parts of an Acoustic Camera is the microphone array. It determines the spatial distribution of the acoustic microphones and therefore measurement performance of the whole system. In order to achieve the maximum possible performance in any given application, we offer a wide variety of microphone arrays. No matter if the measurement is beamforming, intensity or holography ... we have the right microphone array. For special applications we can design and build custom made microphone arrays according to the requirements of the application.

Linear Acoustic
Audio over IP (AoIP) has been embraced by the radio side of broadcasting for many years where the myriad advantages of networked audio via the Livewire+ AES67 standard is well known. Now, AoIP is available for television audio thanks to Linear Acoustic AERO.soft™. The Linear Acoustic SDI xNode de-embeds two separate HD/SD-SDI inputs, converts it to up to 16 channels of Livewire+ AES67 audio, makes it available for processing, upmixing, and encoding in the brand-new AERO.soft Processing Engine, and then re-embeds the audio into two independent SDI outputs. This provides unmatched flexibility, scalability and channel density.

Long Baseline (LBL) Systems
Teledyne Benthos offers a full line of subsea acoustic communication based products that can be configured in many different ways, including into Long Baseline (LBL) positioning systems.Benthos modems and acoustic releases can be set up as transponder nodes, either fixed or mobile, that can be used to calculate range between any one node and the others. The distance between the transponders is usually hundreds, if not thousands, of meters, hence the name Long Baseline. With the inclusion of telemetry, a network can adapt to changing transponder positions to provide greater operational flexibility.
