Embodiments relate to enhancing echo cancellation in a transceiver integrated circuit (IC) for full-duplex communication by providing a signal path connected to a dummy driver that replicates a signal path between a main driver and a counterpart transceiver IC to cause a duplicated signal generated ...

The integrated Sync Control feature eliminates clock jitter by synchronizing the ADC to the playback clock domain, a critical advantage for systems running acoustic echo cancellation algorithms. CONEXANT SYTEMS UNVEILS 4-CHANNEL USB VOICE CAPTURE IC Highlights include all-new streaming capability, the ne...
ACOUSTIC ECHO AND NOISE REMOVAL Sebastian Braun, Maria Luis Valero Microsoft Corporation, USA {sebastian.braun, maria.luis}@microsoft.com ABSTRACT Neural networks have led to tremendous performance gains for single-task speech enhancement, such as noise suppression and acoustic echo cancellation (AEC)....
i am usign PCM2912A ic for audio module mic and speaker voice are best but some time noise add and create echo in output side so please give me solution. Ronak, The PCM2912a does not have any Echo cancellation, This would need to be done on the software side if it is needed. ...
One of the main difficulties in echo cancellation is the fact that the learning rate needs to vary according to conditions such as double-talk and echo path change. In this paper we propose a new method of varying the learning rate of a frequency-domain echo canceller. This method is based...
