Intercom & IoT

Smart solutions for better communications.

Echo Canceller and Noise Reduction

Field-proven, full duplex, up to 48kHz complete solution for any communication application, removing echo and noise without artifacts.

Solution to improve ASR Speech Recognition performance

Through bdSound microphone array technology and high quality processing, hot words and speech recognition success rate is improved. The best solution for smart devices.

Reference Design for a SIP Intercom on a Cortex M4/M7

Using a single ARM Cortex M4 or M7 processor, it is possible to integrate top-quality AEC and Noise Reduction, a full SIP client. A reference design and demo board are available.

Acoustic and Electroacoustic Design Support

A good design starts from the beginning: the electroacoustics design has a strong impact on speech processing algorithms effectivness. We provide complete electroacoustics and acoustics design support to take the first step in the right direction.

A full featured SIP intercom, with stunning audio quality and lots of features. Ready in a while.

MSA: more than a simple SIP intercom

MSA is more than a SIP intercom unit with a stunning full-duplex wideband audio quality, based on ARM Cortex M7. It is a small (55x55mm) PCB with lots of features, fully programmable through a GUI and POE enabled. It embeds a stereo 2x3W audio amplifier and two MEMS microphones, even though it is possible to connect an external amplifier and an external microphone. It has a relay on board, programmable outputs and a multilevel input. It can store prerecorded audio that can be played through a remote command. And many other features…

Our technology is used in different critical and harsh environments, like hospitals.

Robust technologies for Healthcare Intercoms

Hospitals requires clear and reliable communication systems to ensure safety for their patients and efficiency of medical staff. bdSound technology is successfully used in healthcare applications, hospital intercom devices, to enhance quality of hands-free communication between patients, nurses and doctors. Clear audio also with far and weak talker ensure robust communications and safe operations.

Clear and loud also from far and weak talkers


Where reliability is a must

Air, train and maritime communications

Thanks to the expertize in the FPGA field, bdSound solutions are used in Air Traffic Control, Train and Maritime Transportation and other Critical Communications areas

FPGA based communications

There are applications were reliability is a must. These include, for example, any transportation application, like trains, maritime and air. Thanks to the robust solutions combined to the support of several processors, including FPGA, bdSound has been chosen for Air Traffic Control, satellite communications on airplanes, naval and train communication systems.
