Precursor on Audio with FPGA and SoC

bdSound was pioneer in introducing FPGA on professional audio applications. Over the years a full set of IPs and architecture has been developed and available to customers.

A flexible solution that includes a wide set of IPs for interfacing, processing, acquiring, reproducing, routing and mixing audio signals. bdSound’s proaudio architecture boosts the development of innovative products.

Thanks to the fast interface it is possible to combine the benefits of programmable logic and powerfull processors like ARM® Cortex® A in SoC and MCSoC like Xilinx® Zynq® and Ultrascale+®.

bdSound is a Xilinx partner.

bdSound can support your product development from the idea to the manufacturing

From scratch to the final product

Our experienced team provides complete product design support, from technical specifications definition to production ramp-up support, throughout any phase of the product development.

A comprehensive support include hardware and software design, integration, customization. A rich set of IPs and technologies completes the offer to shorten product time-to-market.

We also provide electroacoustic design support for testing and measurements in our anechoic chamber.

S2C - A complete solution for Speech Quality Enhancement

Echo Cancellation and Speech Processing

Since the beginning of its story, bdSound has provided top-grade speech quality enhancement solutions to customers in several markets. One of the globally recognized IP is the bdSound’s proprietary Acoustic Echo Canceller.

A true full-duplex, full band, high quality, robust and reliable echo cancellation processing. As a part of a more global speech quality enhancement solution, Noise Reduction, Speech Processing, Dynamic Control, and more, are included.

bdSound’s AEC set the reference in speech processing and help turning any communication application into a top-grade one.

S2C - A complete solution for Speech Quality Enhancement

VoIP SIP Integrated Client

Integrating communication channels, both VoIP and traditional phone line, is straighforward.

bdSound can provide a fully compliant SIP client on several platforms, from ARM Cortex A even down to ARM Cortex M, with limited features. bdSound also support integration with widely used SIP stack like PjSip.

And, of course, all the solutions include the proprietary Acoustic Echo Canceller, the optional Line Echo Canceller – if required -, noise reduction and all the speech enhancement tools for perfect hands-free calls in any environment, even the most noisy and reverberant.

Smart clock management, drift control and asynchronous sample rate converters to manage different clock domains with no hassle

Easily manage different clock domains

Modern audio applications involve hundreds, even thousands, of audio channels, from different sources at different rates under different clock domains.

Relying on bdSound’s configurable (performance/channels/rates) Asynchronous Sample Rate Converter up to 146dB of Dynamic Range and on specific technologies, managing several clock domains in the same product, with no loss in quality, is easy.
