Adaptive Digital releases HD acoustic echo cancellation for TI Sitara AM335x processors

Adaptive Digital Technologies said its high definition acoustic echo canceller handles extraordinary echoic challenges and delivers exceptional voice quality.

Adaptive Digital´s latest challenge: hospital intercom Nurse Call Systems. Under this most arduous of circumstance, hospital acoustics, Adaptive Digital´s proprietary HD AEC algorithm was able to provide exceptional voice quality while achieving full-duplex performance. Adaptive Digital´s robust HD AEC enabled clear voice communication path between the patient/nursing staff communicator unit and the nurse station console in an acoustically challenging hospital environment.

Adaptive Digital´s HD AEC is well suited to address all of the environmental issues required. HD AEC is a complex algorithm which includes noise reduction (NR), as well as anti-howling, adaptive filtering, nonlinear processing, microphone selection, gain and microphone equalization and double-talk detection.

Adaptive Digital is an industry-leading provider of voice technology. Adaptive Digital´s products include high definition acoustic echo cancellation (HD AEC), HD stereo acoustic echo cancellation (HD SAECâ„¢), Packet, line and Network Echo Cancellation, Voice Engine with SIP, high-density conference engines, speech compression, telephony, and voice-quality algorithms across many platforms.

Adaptive Digital uses a proprietary fast converging adaptive filter and non-linear processor to deliver robust double talk performance even in harsh conditions.

The full featured HD AEC Solution runs on a Texas Instruments TMS320C6748 fixed- and floating-point digital signal processor (DSP). The TMS320C6748 DSP enables original-equipment manufacturers (OEMs) and original-design manufacturers (ODMs) to quickly bring to market devices with robust operating systems, rich user interfaces, and high processor performance through the maximum flexibility of a fully integrated, mixed processor solution. The solution supports up to five microphones, and up to 400 millisecond room echo tail length.
