improves the sound quality of an automixer, for example, by preventing it from bring-
ing the noise level up and down when microphones are gated on and off. By cancel-
ling the noise picked up by each microphone, the overall signal to noise ratio (SNR) is
preserved. The result is crystal clear speech over a greater decibel range than any
other echo canceller. That means reduced listener fatigue and a higher quality audio
conference.
