2-mic, turnkey solution for smart TVs, soundbars and set-top boxes. Delivers far-field voice capture with close range precision.

The Interference Canceller nulls point noise to cancel out typical noise in the soundscape, Stereo Acoustic Echo Cancellation suppresses unwanted speaker echo and enables barge-in across audio playing from the device, while noise suppression removes background noise from other devices. Our Automatic Delay Estimator adjusts audio reference signal latency dynamically, ensuring the Acoustic Echo Cancellation algorithms deliver a smooth, real-time barge-in experience.
