  • Fast engine tracks immediately any change in acoustic path
  • Handle echo paths with negative ERL (gain from speaker to microphone)
  • Always stable
  • Double Talk Detector
  • Voice Activity Detector
  • Adaptive residual echo canceller
  • Very low CPU consuming

Supported Operating Systems

  • Android
  • iOS
  • Linux Embedded

Scalable Solution
