Audio for Communications IPs and products to transmit speech signals over different media: from single pair of cheap wires, to ethernet cables for VoIP/SIP calls. A reliable USB Bidirectional Stereo Audio stack for STM32 microprocessors family completes the offer.
bdSound has successfully integrated a full SIP client endpoint, including also its technology for Speech Quality Enhancement S2C, into a single ARM® Cortex® M4 or ARM® Cortex® M7 microprocessor. An example of application of this IPs is the MSA reference design.
bdSound can provide a ready to use SIP endpoint client, also with the Speech Quality Enhancement technology S2C embedded, into any ARM® Cortex® A, including MSoC and MPSoC. Versions for x86/x64 processors are available too. Different options are available according to the target application, like intercom, video collaboration PC application, custom embedded communication modules and mobile applications for smartphones. An example of application of this IPs is the MSA+ reference design.
Compared with the SIP Client on ARM Cortex M, the version for ARM Cortex A and x86/x64 family is full-featured and oriented to an high-grade SIP application, from intercom to videocollaboration PC application, from embedded to mobile.
Currently we support the following operating systems: Microsoft Windows, Apple OSX, Linux, Android and Apple iOS.
A complete, low size, library to embed into any STM32F4 o STM32F7 processor, with USB port, a bidirectional audio USB protocol.
The USB audio library is a ready-to-use and field-proven solution to create USB audio devices with advanced audio and speech processing options, or just to capture and render audio; from intercom panels to sound card design; from professional audio to consumer audio application.
In many legacy intercom installations, wires were walled, leading to a big work and cost when you wanted to change intercom system.
bdSound 2WBD is a robust and reliable solution that can be used to carry audio and data on a single pair of wires, up to 500m, on a single bus, with digital audio quality. With support for wideband audio, broadcast mode for music and alert distribution, conference mode and up to four two-ways full-duplex concurrent calls, 2WBD is a flexible and easy to implement technology.
Finally, 2WBD is short circuit protected, can carry power supply and is polarity safe.
