Echo cancellation eliminates echo in a two-way voice transmission. Picus Tech implementation of AEC uses subband filter approach compensating echo in each sub band. The approach allows for superior cancellation. The echo cancellation as well as adaptation continues during double talk greatly enhancing the user experience.
