Technologies

Innovation at your fingertips

Acoustic Echo Canceller (AEC)

Full duplex Acoustic Echo Cancellation integrated with Noise Reduction and Speech Quality Enhancement, up to 48kHz of sample frequency.

Line Echo Canceller (LEC)

Light-weight, fast and reactive, full-duplex Line Echo Canceller for traditional communication equipment with 2-wires to 4-wires electrical interface.

Noise Reduction (NR)

Noise reduction removes unwanted noise from audio, without additional distortion, for a comfortable communication.

Beamforming

Multiple microphones arrays with selective beamforming, to improve audio quality in communications and in speech recognition.

Multichannel Barge-In

Interact naturally with voice assistant with the possibility to interrupt it or call it during music reproduction.

ASR Enhancer

Improve success rate of voice commands recognition with a dedicated processing, with less false activation and better understanding.

In-car Communication (ICC)

Safe and comforable communication in-car between front and rear passengers thanks to BdSound ICC solution.

Audio Quality Enhancement

A complete set of standard filters, DRC, AGC and other processing blocks, to fine tune audio quality and optimize loudspeakers’ and microphones’ performance.

SIP/VoIP Stack for Embedded Systems

Integrated SIP stack for VoIP communication also in a small ARM Cortex M, seamlessly integrated within S2C.

Asynchronous Sample Rate Converter

A scalable asynchronous sample rate converter, up to 145dB of Dynamic Range, with a special module to align drifting clocks, easy to be integrated in any design with multiple clock domains needing to be synchronized.
