Consejos Útiles y Definicione
Adaptive Filter: This process uses the Finite Impulse Reponse (FIR) Filter created from the Room Impulse Response by applying it to the Far-End to predict what it will sound like after traveling through the room
Adaptive Algorithm: This process analyzes the result of the subtraction operation and adjusts the Adaptive Filter accordingly.
Double-Talk Detector (DTD): This detector only lets the Adaptive Algorithm do its job when the Far-End is speaking and the Near-End is not.
Non-Linear Processor (NLP): This process analyzes the audio for any remaining residual Far End echoes and attenuates the appropriate sections.
Noise Reduction (NR): This process eliminates steady background noises in the Near-End.
Comfort Noise (CN): This process reintroduces soft white noise to prevent the line from sounding like a disconnection.
