With a strong focus on providing optimum voice quality, Adaptive Digital developed an echo canceller unparalleled in quality and efficiency. The “carrier-grade” echo canceller carries with it the robustness that comes from the combination of careful design, relentless testing, and widespread deployment.

The G.168 Plus™ packet EC has the distinctive ability to handle round-trip delays of up to 512 msec. This ability coupled with a built-in awareness and handling of packet-loss makes G.168 Plus uniquely suitable for VoIP applications.

Adaptive Digital’s G.168 EC features, enhanced beyond ITU recommendation include tandem free operation, dynamic NLP, rapid convergence, convergence monitor, stationary signal detector, split pre and post processing, and the ability to cancels multiple reflectors.

G.168 EC Highlights

  • Superior Voice Quality
  • Rapid, deep convergence
  • Low MIPS
  • No divergence due to doubletalk
  • Matched Comfort Noise Generator
  • Tone Disabler

ACOUSTIC ECHO CANCELLATION

Adaptive Digital’s acoustic echo canceller (AEC) enables true full-duplex hands-free telephony in mobile phones, speakerphones, and hands-free intercoms.

AEC Highlights
AEC G4 – Designed for high-end speakerphones and conferencing endpoints. Supports HD Voice, integrated noise reduction and AGC, supports tail length up to 256 msec, superior double-talk performance. C6000™, ARM, and x86 platforms

AEC G2 – Designed for traditional speakerphones, with enhancements specifically designed for mobile handsets. C6000, C5000™, ARM, and x86 platforms
